    2016-01-01

    The paper studies the influence of Gordon Tullock (1967) and the rent-seeking literature more generally on the study of corruption. The theoretical corruption literature with its emphasis on principal-agent relationships within government and rent creation by corruption politicians has largely, but not entirely, overlooked that contestable rents encourage unproductive use of real resources in seeking these rents. As a consequence, the literature underestimates the value of corruption control ...

  4. Stochastic Control Model on Rent Seeking

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    A continuous-time stochastic model is constructed to analyze how to control rent seeking behaviors. Using the stochastic optimization methods based on the modern risky theory, a unique positive solution to the dynamic model is derived. The effects of preference-related parameters on the optimal control level of rent seeking are discussed, and some policy measures are given. The results show that there exists a unique solution to the stochastic dynamic model under some macroeconomic assumptions, and that raising public expenditure may have reverse effects on rent seeking in an underdeveloped or developed economic environment.

If agents can choose between acting asrent-seekers and engaging in productive activities, and only productive skills are exportable,a positive probability of migration (to a more secure economy) reduces therelative expected returns from rent-seeking, thus decreasing the proportion of skilledworkers who opt for ”parasitic” activities.

    This paper explores the asymmetric adjustment speed of gasoline price in twelve European Union (EU) countries transmitted directly in a single stage formulation. The empirical results shed new light on the taxation effect and its role to the price asymmetry nexus, pointing that in many EU countries a crude oil price increase is passed through more forcefully than a price decrease revealing a rent-seeking oligopolistic behaviour by the marketers.

    Full Text Available Rent seeking behavior has been amongst noticeable obstacles in path of economic growth and development for developing communities. Due to this the study aims at testing the hypothesis that the Rent seeking behavior among bureaucracy is being influenced by the openness of economy as well as inflows of foreign investment significantly. Model estimations imply that reforms may have an insignificant impact upon impact upon curtailing the rent seeking behavior among bureaucracy in a time series setting therefore this research will use two statistical econometric models to show the effect of corruption on the foreign direct inflow received in Pakistan. In order to pretest the impact of all the mentioned variables on rent seeking behavior generalized least square was used because its results were unbiased, consistent and the problem of Serial correlation was solved by using it. In order to quantify rent seeking behavior among bureaucracy different aspects of misuse of public offices appearing in form of petty and grand corruption were used using the variables informal sector, tax evasion, judicial outlay, G.D.P and F.D.I as percentage of G.D.P. All of the variables had proper signs aligned with the theory and all of the variables appeared to be significant except judicial outlay proving that the judiciary has been incompetent and ineffective. The robust regression showed all the same signs except in it every variable was appearing to be significant. Rent seeking corruption has been highly affecting Pakistan in adverse ways and this paper will show how many factors like judiciary is not playing effective role in limiting corruption and also how the economy is being affected by rent seeking behavior.

    CERN Document Server

    Dompere, Kofi Kissi

    2014-01-01

    This volume presents an analysis of the problems and solutions of the market mockery of the democratic collective decision-choice system with imperfect information structure composed of defective and deceptive structures using methods of fuzzy rationality. The book is devoted to the political economy of rent-seeking, rent-protection and rent-harvesting to enhance profits under democratic collective decision-choice systems. The toolbox used in the monograph consists of methods of fuzzy decision, approximate reasoning, negotiation games and fuzzy mathematics. The monograph further discusses the rent-seeking phenomenon in the Schumpeterian and Marxian political economies where the rent-seeking activities transform the qualitative character of the general capitalism into oligarchic socialism and making the democratic collective decision-choice system as an ideology rather than social calculus for resolving conflicts in preferences in the collective decision-choice space without violence.

    We analyze an institutionalized rent-seeking game in which groups can endogenously choose the prize at stake, e.g. a common-pool resource. In the first stage, groups determine how much of the resource to protect and equally share. In the second stage, the unprotected fraction is competed for in a rent-seeking game. We consider two institutions varying in the extent by which subjects participate: majority voting (i.e. "unrestrained participation" where all group members participate in the prot...

  16. The welfare costs of rent-seeking: a methodologically individualist and subjectivist revision

    Directory of Open Access Journals (Sweden)

    Michael Makovi

    2015-11-01

    Full Text Available Gordon Tullock is acknowledged for being the first to recognize the true costs of rent-seeking as including not only the Harberger triangle but also the Tullock rectangle. This rectangle does not constitute merely a lossless transfer of wealth, but it causes a misallocation of resources as rent-seekers invest resources in lobbying. However, a close reading of Tullock’s writings shows that his arguments are formulated in a holistic fashion, speaking of what is efficient or inefficient for society. Rent-seeking is inefficient because it reduces societal welfare. But according to a methodologically individualist and subjectivist economics, such a claim is invalid. We must distinguish between positive economic fact and normative moral philosophy. We call for a reconstruction of utility and welfare economics based on methodological individualism and subjectivism with implications for the theories of monopoly and competition: practices which Neoclassical perfect-competition theory considers to be evidence of rent-seeking should instead be deemed as indications of genuine competition Political economy should be concerned with ascertaining which institutions will best enable individuals to pursue their individually subjective ends – or else economists should be explicit about their normative preferences and political philosophies.

    2005-01-01

    The rent-seeking theory has its unique explanatory power, but it is not spared with limitations. The author used a case in the treasury transportation industry to discuss the limitations of the rent-seeking theory and, on the basis of the capital asset combination theory as well as the neo-institutional economy, proposed dynamic combination of institutional factors as a new perspective. It was contended that, any institution being an important factor, such factors combined would impact the profit or risk outcomes of business activities. Therefore, enterprises would be motivated to apply the method of combining factors in production to the institutional sector, i.e., trying to dynamically combine institutional factors in order to enhance profits and reduce risks associated with their activities.

    In library there are some rent-seeking phenomenon which are dominant, recessive rent-seeking and rent-seeking in the process. The behaviors of rent-seeking come from the attribute paradox of the literature information, the value choice of libraries and librarians and the defects of library management system.

    In recent years, both financial accounting and tax researchers focus increasingly on accounting for income taxes (AFIT), so much so that AFIT has become the most active area of accounting research in taxation which is one of the more complex areas of financial reporting. Graham et al. (2012) comprehensively reviews the Accounting for Income Taxes literature from top 3 journals (Accounting Review, Journal of Accounting and Economics and Journal of Accounting Research). Almost all of the studies have been empirical, primarily testing the incremental information content of the tax accounts and their role in earningsmanagement. The findings can be condensed into a broad generalizations. Managers use the tax accounts to manage earnings to meet or beat analysts' forecasts, but not for other objectives, such as to smooth earnings, increase a big bath, avoid losses, meet/beat prior earnings, or other opportunism incentives. The government (federal, state, and local) takes a greater than one-third share of a firms' pre-tax profits. Given the significance of this tax cost to the firms and shareholders, it might be expected that tax aggressiveness is desired by shareholders. However, this argument ignores potential non- tax costs that can accompany tax aggressiveness, especially those arising from agency problems. Tax is only regarded as one of the market frictions in previous literature. Agency relationship and agency conflict exist between shareholders and managers. The nature and extent of agency conflicts, such as the costs arising from hidden actions of managers can affect the level of tax aggressiveness. Desai and Dharmapala(2008 ), Desai et al. (2007) argue that the critical characteristics of tax aggressive activities are complexity and obfuscation. Such complexity could be used for managers to mask rent extraction, such as earnings management, related-partytransactions, and other perquisite consumption behavior. This agency perspective on

Then it takes rent-seeking as an example to build the game model and makes the analysis to find that,as long as the rent-seeking cost is less than the penalty cost,food producers are likely to seek rent from regulators. Therefore,government regulation behavior itself must be supervised by publics to solve problems of food safety better.%对我国食品安全问题的政府监管进行研究,认为政府监管也存在效率不高和政府失灵的问题,然后以寻租为例建立博弈模型进行分析,发现只要寻租成本低于处罚成本,食品生产者就有可能向监管者寻租,因此政府监管行为本身也要受到社会监督,才能更好地解决食品安全问题。

    Full Text Available The urgent task for the effective functioning of the national economy is the need to reflect income from the use of forest resources in accounting, which will allow management personnel to prove the effectiveness of environmental protection measures, to assess the amount of expenses taken during restoration and protection of forest resources. The study aims at identifying characteristics of forest rent to determine the amount and its reflection in the accounting for its management. The author understands a forest rent as the income received from the owner of forest resources. The above procedure for determining the amount of forest rent can be used to display it in the accounting. A forest rent is a type of business income, so for its reflection in the accounting it is proposed to open the analytical accounts to account 79 named «Financial results». To determine the amount of forest rent and its reflection in the accounting the author suggests the calculation form of a forest rent. In order to manage the size of a forest rent and expenses incurred to obtain it the author proposes to use the information from the developed report about the forest rent formation. The displaying forest rents in accounting will provide accurate and deep information to the management about the revenue and assets of a company. The rational use of forest resources and accounting reflection of a forest rent will strengthen control over the influence of human activity on natural resources and keep the conception of sustainable development.

    Full Text Available Lease of agricultural land is a form of the land use. It enables to create or increase a farm, without having to pay capital-expenditure related to the purchase of land. In exchange for the land lease, the tenant agrees to pay a rent, which is a constant burden on its budget and can affect the economic situation of the farm. Changes in the value of rent result in, to a large extent, deficit of land in some areas of Poland, increase of prices and demand for agricultural land. The aim of the study was to analyse the determinants and dynamics of changes in the rates of agricultural rents. The source material for the study were data on the agricultural land market in Poland in 2000-2011 published by the IERiGŻ and GUS.

    make efforts to affect the dimension and the strength of administrative license in alteration of chartered real right. Once the rent-seeking behaviors take place successfully, the legal alternation path of natural resources would be distorted and the overall social welfare would be decreased. The rent-seeking behaviors in the alternation of chartered real right could be divided into two types,including exclusive rent-seeking and competitive rent-seeking , which have the common derivation path. The special derivation causes of rent-seeking behaviors in the alteration of chartered real right of natural resources can be divined by tracking the derivation path of the rent-seeking behavior, and as a result, the rent-seeking causes can be effectively inhibited by means of the measures such as the structural rationalization of the chartered real right, the normalization of alternation order of chartered real right and the enhancement of restriction strength of administrative license right and the like.

    The purposes of this research were to examine the characteristics of those who look for physical activity-related information, where they find it, and to examine what types of physical activity-related advertisements are recalled (i.e., publicly funded or commercial). These purposes were tested using secondary data analyses from two population health surveys. Results from the first survey (n=1211) showed gender, age, education, and activity-level differences in who is more likely to search for physical activity-related information. Adding the goal of being active into the model made age and activity level no longer significant but gender and education remained significant factors. The Internet was the most often cited source of physical activity information. The second survey (n=1600) showed that adults 55 years of age or older and participants with the least amount of education were more than twice as likely to name commercial advertisements than were participants aged 18-54 years or those with more education. These results help further our understanding of how publicly funded promotional campaigns fare against commercial advertising and also highlight the need to understand physical activity information-seeking behavior on the Internet and its implications for health promotion.

So, our government encourages returned rural migrant workers to start businesses in their hometowns and expands channels for seeking employment and starting businesses. Relevant domestic departments and research institutes have also carried out extensive studies and discussions. Faced with the subsidies from the governments, migrant workers who have the priority of the private information, whether or not obtain the subsidies through legal means? Do they will misstate their information or subsidize that are even belonging to them? At the same time, do the executive departments of the government, who have the power of the allocation of resources, will accept the rent-seeking from the migrant workers? In addition, what measures will the government regulatory agencies that are on the behalf of the fair take? Therefore, three game models are built and the authors fulfill a survey to perfect conclusions. Finally, this paper also gives some recommendations to standardize the order of distribution of subsidies. The main results of this paper are as following: ( 1 ) If there will be a number of subsidies from the government, migrant workers who are very rational must be thinking of comparing their cost and benefits, then they will lie or seek rents. If two independent of migrant workers play the game which is called First-Price-Sealed Bid Auction, both of them will subsidize. (2) We suppose that there are only two parties : the migrant workers and the executive departments of the government participate in the game. The conclusions are: no matter how many migrant workers subsidize, the executive departments of the government will be agreed. Especially the more migrant workers subsidize, the more benefits are gained by the executive departments of the government. (3) Lastly, there have been three parties are playing the game, which is called The

  6. Rents in property rights creation and implementation

    Directory of Open Access Journals (Sweden)

    Žarković Jelena

    2006-01-01

    Full Text Available The institution of property rights is increasingly being recognized as an essential building block of an economically prosperous society. The question that remains unanswered however, is how do we develop effective property rights institutions? The literature dealing with the development of property rights tends to be, in general, overly optimistic since there is a tendency to view the design of property rights institutions as optimizing decisions to economize on transaction costs and to facilitate new economic activities. On the other hand, since property rights define the distribution of wealth and political power in a society changes in property rights structures are likely to be influenced by more than pure efficiency considerations. Therefore, in order to achieve a balanced analysis of the evolution of property rights institutions our article introduces the state in the whole process. Following the propositions of the interest group theory of government we show an important relationship between rent seeking and state involvement in property rights creation. The state with a coercive power to establish and enforce property rights can also use that power, through the process of economic regulation, to redistribute property rights to politically influential interest groups. Herein lies the state failure in property rights creation.

    Full Text Available There is the urgent necessity of the transition to a higher level of economic relations in the system of environmental management in the present conditions of economy of the country. As a result, the issues like formation of information support for water rent management, determining the ways of its calculation, distribution as well as usage of water rents require urgent solutions. The study focuses on the essence of water rent and forming organizational and methodological provisions of its accounting reflection to ensure sustainable ecological and economic development of the enterprise. As a result of research the classification of water rent, that affects reflection of such rent in accounting has been formed. It is established that the amount of water rent for accounting reflection can be defined as the difference between actual and normal profit of enterprise-water users. A number of analytical accounts of first and second order as well as the typical correspondence of accounts for accounting reflection of water rent have been suggested. The information from the Report on the formation of water rent that contains data on the sources of payback of expenses incurred for the maintenance of water bodies and the impact of ecological condition of water body on the size of water rent has been suggested to be used in order to manage the size of water rent and expenses incurred to obtain it. Thus, determining the amount of water rent will allow management personnel to adjust the activity of the company in accordance with the strategic objectives of the company’s development regarding the profitability and compliance with the concept of sustainable development.

    Katz, Abigail Sherman; Pronk, Nicolaas Petrus

    2014-02-01

    Physical activity is regarded an important health behavior. Routine doctor visits, dentist visits, and willingness to seek phone advice from a nurse are considered important care-seeking behaviors (ie, behaviors that reflect the way in which people seek and access health care delivery resources available to them). Employers promote physical activity as well as care-seeking behavior to protect and promote health, optimize productivity, and manage health care costs. The purpose of this study was to investigate the association between physical activity and 3 care-seeking behaviors among a sample of 5500 employed adults. Data were obtained from employee health assessments. Logistic regression was used to test the relationship between physical activity and care-seeking behavior. Physical activity was positively associated with all 3 measures of care-seeking behavior: doctor visits (P employees with and without chronic conditions.

  14. Neural Networks Modelling of Municipal Real Estate Market Rent Rates

    Directory of Open Access Journals (Sweden)

    Muczyński Andrzej

    2016-12-01

    Full Text Available This paper presents the results of research on the application of neural networks modelling of municipal real estate market rent rates. The test procedure was based on selected networks trained on the local real estate market data and transformation of the detected dependencies – through established models – to estimate the potential market rent rates of municipal premises. On this basis, the assessment of the adequacy of the actual market rent rates of municipal properties was made. Empirical research was conducted on the local real estate market of the city of Olsztyn in Poland. In order to describe the phenomenon of market rent rates formation an unidirectional three-layer network and a network of radial base was selected. Analyses showed a relatively low degree of convergence of the actual municipal rent rents with potential market rent rates. This degree was strongly varied depending on the type of business ran on the property and its’ social and economic impact. The applied research methodology and the obtained results can be used in order to rationalize municipal property management, including the activation of rental policy.

  18. Frontal lobe activation mediates the relation between sensation seeking and cortisol increases.

    Science.gov (United States)

    Freeman, Hani D; Beer, Jennifer S

    2010-10-01

    Low sensation seekers are theorized to avoid risk more often because risk is emotionally more costly for them (in comparison to high sensation seekers). Therefore, individual differences in sensation seeking should predict differences in risk task-induced cortisol changes. Furthermore, the neural mediation that accounts for the relation between sensation seeking and cortisol changes has not been studied. The current study tested whether individual differences in sensation seeking predicted cortisol changes in relation to a risk task and whether this relation was mediated by frontal lobe activation. Participants (N=17) who varied in sensation seeking completed an fMRI study in which they rated the likelihood they would take various risks. Cortisol was measured from saliva samples collected prior to and after the fMRI procedure. The findings show that low sensation seekers showed the greatest rise in cortisol after the risk procedure, and this relation was partially mediated by increased orbitofrontal cortex activity.

  2. LIFE STYLE OF RENTED LAND OWNERS IN UBUD SUBDISTRICT

    Directory of Open Access Journals (Sweden)

    2015-02-01

    Full Text Available This present study was intended to analyze the Life Style of the Rented Land Owners at Ubud Subdistrict. The problems of the study are formulated as follows: (1 what is the characteristic of the rented land owners at Ubud Subdistrict like? (2 How has the process of life style of the rented land owners at Ubud Subdistrict  taken place? And (3 what is the implication of the life style of the rented land owners on their lives? Qualitative method was employed in the study. The data were processed using observation, interview and documentary techniques. The workability of the law regulating the demand for land at Ubud Subdistrict motivated the land owners to rent out their land to investors. Apart from that, the internal dimension, which is made up of the economical capital, was the most important element as it could activate small, medium and big enterprises. Another aspect was image which was reflected through perception, cognition, motivation, and attitude of individuals as consumers. As an illustration, they built luxurious houses and showed off luxurious cars to show the image that they were new wealthy people. On the other hand, there was external dimension, namely, the highly rapid development of tourism, which could positively and negatively contribute to the life style of the people living at Ubud Subdistrict. Such an implication could not be avoided. The other aspect was consumerism; the consumers were around the symbol and sign. Mass media were the miracles of the object liturgy; pleasure was defined as the realization of freedom, and the human body was the main object of consumers. The last aspect was the government’s policy which determined that Ubud Subdistrict was a tourist destination. As a result, the local people had the opportunity to rent out their land which was used to expand the industry of tourism and to activate the other economic enterprises.

  3. The Capitalism, Rent and Democracy

    Directory of Open Access Journals (Sweden)

    Victor S. Martyanov

    2017-03-01

    Full Text Available By inertia, which derives from Adam Smith, modern capitalism is described as a free-market competition. This historical model has worked while the market expands and the availability of resources increases. It provided the opportunity to maintain the political order of the welfare state as a form of non-economic egalitarian distribution of resources, which mitigates inequality and class antagonisms generated by market. However, once capitalism has engulfed the whole world, it is more prone to crises: competition intensifies, markets of demand and market outlets do not expand, technological progress creates a growing structural unemployment, economic growth due to the completion of the global village-city transition stagnates, the resources of all the peripheries are almost exhausted. As a result, nationalism and protectionism arise, the polarization between the global center and the periphery increases, and there comes the image of undemocratic and non-egalitarian labor less society on the horizon of the future, with the precariat and the unemployed growing in numbers and demanding large amounts of rent to maintain their livelihoods. Due to this, the market model of capitalism is gradually transforming into a rental one, where the pursuit of profit, the main motivational factor intrinsic to the market, is removed by the pursuit of rent and the redistribution of markets by non-economic ways. In this context, the state becomes the key economic actor, which distributes resources by extra-market means within the hierarchy of rental groups that form the framework of a new structure of the political community.

    Reviews historical concept of ground rents with reference to works of Adam Smith and David Ricardo and to 19th century capitalism and Marxism-Leninism. Asks whether mine rents can exist under a socialist system and examines theoretical basis for mine rents, which includes socio-economic aspects, geological conditions, proximity to markets and environmental considerations. Compares mine rents with agricultural land rents and analyzes value of end product (coal) and effect of pricing method on it. Explains pricing system in Czechoslovakia, which involves 3 groupings: coking coal, coke and energy coal (including briquets), the price of each of which is set according to average costs and geological conditions. Surplus revenue (or positive mine rent) only arises therefore at mines where the production costs are lower than fixed trade prices. Discusses in general terms application of new economic system (perestroika) to concept of mine rent and assessment of mine profitability and concludes that method of pricing solid fuels will play a decisive role. 4 refs.

  9. Science teachers' online strategies for seeking inquiry-based lesson activities

    Science.gov (United States)

    Lenell, Elizabeth Ann

    This paper reports the findings of a mixed methods study that examines how 9th grade science teachers engage in online searches for inquiry-based activities in two different search engines---Google and the Digital Library for Earth System Education. The goal of this dissertation was two-fold: (a) to detail science teacher search behaviors during a realistic online search task related to their teaching, and (b) the effect of search engine affordances on those search practices. At the center of the dissertation activities were an experimental task and talk-aloud protocols of the teachers engaged in the task. The task itself asked teacher participants to search for earth science activities linking the concept of volcanism to plate tectonics. In addition to the experiment and talk-aloud protocol, a demographic survey, content knowledge evaluation, inquiry-based activity evaluation, and post-task structured interview were conducted. Because substantial prior research in non-educational areas has shown that task domain influences search behaviors, it was expected that the science teaching domain would have its own particular influence on teachers' online information seeking. The concept of task domain was developed in terms of an information seeking framework developed by Marchionini (1995). The Marchionini (1995) model of information seeking was used as a guiding framework for the dissertation investigations. The objectives of this dissertation were to characterize the behaviors and products of real-world online information seeking by 9th grade science teachers, and to inform the work of educational software designers.

  10. Relationship between oscillatory neuronal activity during reward processing and trait impulsivity and sensation seeking.

    Directory of Open Access Journals (Sweden)

    Gregor Leicht

    Full Text Available BACKGROUND: The processing of reward and punishment stimuli in humans appears to involve brain oscillatory activity of several frequencies, probably each with a distinct function. The exact nature of associations of these electrophysiological measures with impulsive or risk-seeking personality traits is not completely clear. Thus, the aim of the present study was to investigate event-related oscillatory activity during reward processing across a wide spectrum of frequencies, and its associations with impulsivity and sensation seeking in healthy subjects. METHODS: During recording of a 32-channel EEG 22 healthy volunteers were characterized with the Barratt Impulsiveness and the Sensation Seeking Scale and performed a computerized two-choice gambling task comprising different feedback options with positive vs. negative valence (gain or loss and high or low magnitude (5 vs. 25 points. RESULTS: We observed greater increases of amplitudes of the feedback-related negativity and of activity in the theta, alpha and low-beta frequency range following loss feedback and, in contrast, greater increase of activity in the high-beta frequency range following gain feedback. Significant magnitude effects were observed for theta and delta oscillations, indicating greater amplitudes upon feedback concerning large stakes. The theta amplitude changes during loss were negatively correlated with motor impulsivity scores, whereas alpha and low-beta increase upon loss and high-beta increase upon gain were positively correlated with various dimensions of sensation seeking. CONCLUSIONS: The findings suggest that the processing of feedback information involves several distinct processes, which are subserved by oscillations of different frequencies and are associated with different personality traits.

    Schnyder, Nina; Panczak, Radoslaw; Groth, Nicola; Schultze-Lutter, Frauke

    2017-04-01

    BackgroundMental disorders create high individual and societal costs and burden, partly because help-seeking is often delayed or completely avoided. Stigma related to mental disorders or mental health services is regarded as a main reason for insufficient help-seeking.AimsTo estimate the impact of four stigma types (help-seeking attitudes and personal, self and perceived public stigma) on active help-seeking in the general population.MethodA systematic review of three electronic databases was followed by random effect meta-analyses according to the stigma types.ResultsTwenty-seven studies fulfilled eligibility criteria. Participants' own negative attitudes towards mental health help-seeking (OR = 0.80, 95% CI 0.73-0.88) and their stigmatising attitudes towards people with a mental illness (OR = 0.82, 95% CI 0.69-0.98) were associated with less active help-seeking. Self-stigma showed insignificant association (OR = 0.88, 95% CI 0.76-1.03), whereas perceived public stigma was not associated.ConclusionsPersonal attitudes towards mental illness or help-seeking are associated with active help-seeking for mental problems. Campaigns promoting help-seeking and fighting mental illness-related stigma should target these personal attitudes rather than broad public opinion. © The Royal College of Psychiatrists 2017.

  12. Are physicians profit or rent seekers? Some evidence from state economic growth rates.

    Science.gov (United States)

    Reilly, Mary; Santerre, Rexford E

    2013-01-01

    Previous research has debated whether physicians act as profit- or rent-seekers. We argue that these two models of physician behavior can be tested by observing empirically the relationship between physician density and economic growth rates. A direct (inverse) relationship provides evidence for the profit-seeking (rent-seeking) theory of physician behavior. We empirically examine the impact of physician density on the economic growth of all US states over the period from 1973 to 2009. The empirical analysis generally finds a statistically significant and direct relationship between physician density and the growth of gross state product. The results are robust with respect to state- and time-fixed effects, individual state time trends, and 2SLS (two-stage least squares) estimation. Thus, in support of the profit-seeking theory of physician behavior, the findings reveal that physicians generally have a positive impact on the growth of the US economy.

  18. Celestial marriage and earthly rents: interests and the prohibition of polygamy.

    Anderson, G M; Tollison, R D

    1998-01-01

    Just prior to the Civil War, the US government set out on a relentless campaign to eliminate polygamy within the Mormon Church. This paper offers evidence that the political restrictions on the practice of polygamy were the result of rent seeking by potential beneficiaries of such laws (the Edmonds Act of 1882). Polygamy created benefits for women, but reduced the welfare of most men, in a time period when only adult males had the franchise.

    Infralimbic cortex (IL) is proposed to suppress cocaine seeking after extinction, but whether the IL regulates the extinction and reinstatement of heroin-seeking behavior is unknown. To address this issue, the male SD rats were trained to self-administer heroin under a FR1 schedule for consecutive 14 days, then the rats underwent 7 daily 2h extinction session in the operant chamber. The activation of IL by microinjection PEPA, an allosteric AMPA receptor potentiator into IL before each of extinction session facilitated the extinction responding after heroin self-administration, but did not alter the locomotor activity in an open field testing environment. Other rats were first trained under a FR1 schedule for heroin self-administration for 14 days, followed by 14 days of extinction training, and reinstatement of heroin-seeking induced by cues was measured for 2h. Intra-IL microinjecting of PEPA at 15min prior to test inhibited the reinstatement of heroin-seeking induced by cues. Moreover, the expression of GluR1 in the IL and NAc remarkably increased after treatment with PEPA during the reinstatement. These finding suggested that activation of glutamatergic projection from IL to NAc shell may be involved in the extinction and reinstatement of heroin-seeking.

    2016-06-01

    Background and aims Previous analyses have highlighted significant associations between gambling disorder (GD)/subsyndromal GD and increased rates of anxiety symptoms and anxiety disorders relative to the general population. However, less is known about how anxiety symptoms influence the clinical presentation of gambling problems. The objective of this study was to evaluate the association between anxiety symptoms, gambling activity, and neurocognition across the spectrum of gambling behavior. Methods The sample consisted of 143 non-treatment-seeking young adults (aged 18-29 years), in which 63 individuals (44.1%) were classified as recreational gamblers, 47 (32.9%) as having subsyndromal GD, and 33 (23.1%) met criteria for GD. Results The main findings were: (a) there was a positive correlation between anxiety severity and gambling severity measured by the number of DSM-5 GD criteria met; (b) there was a positive correlation between anxiety severity and attentional impulsiveness; (c) subjects with suicidality presented higher levels of anxiety; and (d) the severity of anxiety symptoms was negatively correlated with the quality of life. Discussion and conclusions This study suggests that anxiety may be associated with relevant clinical variables in the broad spectrum of gambling activity. Therefore, proper management of anxiety symptoms might improve the clinical presentation of gamblers in different areas.

  6. The Influence of Health Literacy and Patient Activation on Patient Information Seeking and Sharing.

    Ledford, Christy J W; Cafferty, Lauren A; Russell, Travis C

    2015-01-01

    This study provided an assessment of how patients looked for information to prepare for a clinical appointment and whether they shared those findings with their provider. A cross-sectional survey allowed insight into patient attitudes, motivations, and behavior in clinical real time. At two hospital-based clinics, 243 patients completed surveys before and after clinical appointments. Younger patients with higher communicative and critical health literacy prepared for clinical appointments with information searches. The predicted association of health literacy and patient activation with information sharing was not supported. This study shows that patients with higher patient activation perceived that their providers responded more positively to patient-obtained medical information. The role of critical health literacy may show that individuals choosing to seek information are considering not just their ability to conduct the search but also their ability to synthesize and critically analyze the results of the information search. An implication for providers is to become skilled in directly asking or passively surveying what outside information sources the patient has engaged with, no matter if the patient does or does not introduce the information.

    Easton, A; Arbuzova, J; Turek, F W

    2003-02-01

    Disturbances of circadian rhythms are associated with many types of mood disorders; however, it is unknown whether a dysfunctional circadian pacemaker can be the primary cause of altered emotional behavior. To test this hypothesis, male and female mice carrying a mutation of the circadian gene, Clock, were compared to wild-type mice in an array of behavioral tests used to measure exploratory activity, anxiety, and behavioral despair. Female Clock mutant mice exhibited significantly greater activity and rearing in an open field and a greater number of total arm entries in the elevated plus maze. In addition, female Clock mutant mice spent significantly more time swimming in the forced swim test than wild-type mice on both days of a 2-day test. Male Clock mutant mice also exhibited increased exploration of the open field and increased swimming in the forced swim test; however, behavioral changes were less robust in Clock mutant males compared to Clock mutant females. These changes in behavior were not dependent on the expression of a lengthened free-running period but were more or less striking depending on the testing conditions. These data indicate that the Clock mutation leads to increased exploratory behavior and increased escape-seeking behavior, and, conversely, does not result in increased anxiety or depressive-like behavior. These results suggest that the Clock gene is involved in regulating behavioral arousal, and that Clock may interact with sex hormones to produce these behavioral changes.

  8. Rents From the Essential Health Benefits Mandate of Health Insurance Reform.

    Science.gov (United States)

    Mendoza, Roger Lee

    2015-01-01

    The essential health benefits mandate constitutes one of the most controversial health care reforms introduced under the U.S. Affordable Care Act of 2010. It bears important theoretical and practical implications for health care risk and insurance management. These essential health benefits are examined in this study from a rent-seeking perspective, particularly in terms of three interrelated questions: Is there an economic rationale for standardized, minimum health care coverage? How is the scope of essential health services and treatments determined? What are the attendant and incidental costs and benefits of such determination/s? Rents offer ample incentives to business interests to expend considerable resources for health care marketing, particularly when policy processes are open to contestation. Welfare losses inevitably arise from these incentives. We rely on five case studies to illustrate why and how rents are created, assigned, extracted, and dissipated in equilibrium. We also demonstrate why rents depend on persuasive marketing and the bargained decisions of regulators and rentiers, as conditioned by the Tullock paradox. Insights on the intertwining issues of consumer choice, health care marketing, and insurance reform are offered by way of conclusion.

    Full Text Available Abstract Background Given that bariatric surgery (BS and lifestyle intervention (LI represent two vastly different approaches to treating severe obesity, there is growing interest in whether individuals who seek BS versus LI also differ on weight-related behaviors. In the present study, we compared BS- and LI-seekers on physical activity (PA and sedentary behaviors (SB, and examined between-group differences in health-related quality of life (HRQoL, while controlling for PA. Findings A sample of 34 LI-seekers were matched with 34 BS-seekers on gender, age, BMI, and PA monitor-daily wear time (age: 42.1±10.0 years; BMI: 45.6±6.5 kg/m2. PA and SB were assessed over a 7-day period via the SenseWear Armband (SWA. HRQoL was measured using the SF-36, with scores standardized to a population normal distribution (M=50, SD=10. Participants wore the SWA for 13.7±1.6 h/day. BS-seekers did not differ from LI-seekers on average min/d over the wear period spent in SB (641±117.1 vs. 638.4±133.4, p=0.62 or light (136.4±76.1 vs. 145.5±72.5, p=0.59 and moderate-to-vigorous (>1-min bouts=36.4±26.2 vs. 40.2±31.3, p=0.59; ≥10-min bouts=5.7±8.3 vs. 10.2±17.0, p=0.17 PA. BS-seekers reported significantly lower SF-36 physical functioning (42.4±10.9 vs. 49.0±6.8, p=0.004 and physical component summary (43.9±10.1 vs. 48.9±7.0 scores versus LI-seekers. BS-seeker group status was related to lower physical functioning (β=0.30, p=0.009, independent of gender, age, BMI, and daily PA. Conclusions Findings suggest that seeking BS versus LI is not related to patterns of PA or SB, and that lower subjective physical functioning is not associated with lower overall PA levels in BS-seekers.

    DEFF Research Database (Denmark)

    Andersen, Torben M.; Sørensen, Allan

    Globalization in the form of product market integration affects labour markets and produces winners and losers. While there are aggregate gains, it is in general ambiguous how inequality is affected. We explore this issue in a Ricardian model and show that it depends on the balance between...... "protection" and "specialization" rents. In particular, wage inequality among similar workers (residual wage inequality) may be U-shaped, at first decreasing and then increasing in the process of product market integration.

  13. It's the rents, stupid. The political economy of the resource curse

    Kolstad, Ivar; Wiig, Arne [Chr. Michelsen Institute, P.O. Box 6033 Postterminalen, N-5892 Bergen (Norway)

    2009-12-15

    A number of studies suggest that natural resources can have a negative impact on the developing prospects of countries. Empirical results suggest that political economy models of patronage and rent-seeking are central to understanding why such a resource curse arises. In other words, the resource curse is created by certain resource rents leading to dysfunctional behaviour. This article introduces the term impartiality enhancing institutions to structure policy debates by distinguishing conditions under which negative effects of resources can be mitigated. Moreover, it is argued that viewing institutions as an equilibrium outcome has implications for the analysis of institutional change. Policy initiatives that do not promote the impartiality of institutions, nor attend to the underlying interests and incentives keeping a bad institutional equilibrium in place, will not help lift the resource curse.

    2016-10-01

    This study investigates the relationships between physical activity (PA), sports participation and sensation seeking or aggression and injury risk in young men. A representative cohort study was conducted with 4686 conscripts for the Swiss army. Risk factors assessed at baseline were PA, the frequency of sports participation, sensation seeking, and aggression. The number of injuries during the past 12 months was reported 16 months after baseline. Exposure to moderate-tovigorous physical activity (MVPA) was estimated based on baseline PA. Among conscripts, 48.5% reported at least 1 injury for the past 12 months. After accounting for exposure to MVPA, the most inactive individuals (reference group) had the highest injury risk and those with high levels of PA and weekly sports participation the lowest (Poisson regression analysis: incidence rate ratio = 0.14 [0.12-0.16]). Independent of activity level, sensation seeking increased cumulative injury incidence significantly (Logistic regression analysis [injured vs. not injured]: odds ratio = 1.29 [1.02-1.63]) and incidence rates marginally. Aggression was marginally associated only with cumulative injury incidence and only in those participating in daily sports. When accounting for exposure to PA, being inactive is a strong injury risk factor in young men, whereas the roles of the personality variables are less clear.

  16. Suppression of activity-regulated cytoskeleton-associated gene expression in the dorsal striatum attenuates extinction of cocaine-seeking.

    Hearing, Matthew C; Schwendt, Marek; McGinty, Jacqueline F

    2011-07-01

    The caudate putamen (CPu) has been implicated in habit learning and neuroadaptive changes that mediate the compulsive nature of drug-seeking following chronic cocaine self-administration. Re-exposure to an operant chamber previously associated with cocaine, but not yoked-saline, increases activity-regulated cytoskeleton-associated (Arc) gene mRNA expression within the dorsolateral (dl) CPu following prolonged abstinence. In this study, we tested the hypothesis that antisense gene knockdown of Arc within the dlCPu would alter cocaine-seeking. Initial studies showed that a single infusion of Arc antisense oligodeoxynucleotide (ODN) into the dlCPu significantly attenuated the induction of Arc mRNA and Arc protein by a single cocaine exposure (20 mg/kg i.p.) compared to scrambled-ODN-infused controls. In cocaine self-administering rats, infusion of Arc antisense ODN into the dlCPu 3 h prior to a test of context-driven drug-seeking significantly attenuated Arc protein induction, but failed to alter responding during testing, suggesting striatal Arc does not facilitate context-induced drug-seeking following prolonged abstinence. However, Arc antisense ODN infusion blunted the decrease in responding during subsequent 1-h extinction tests 24 and 48 h later. Following re-exposure to a cocaine-paired context, surface expression of the AMPA-type glutamate receptor GluR1 was significantly reduced whereas GluR2 was significantly increased in the dlCPu, independent of Arc antisense ODN infusion. Together, these findings indicate an important role for Arc in neuroadaptations within brain regions responsible for drug-seeking after abstinence and direct attention to changes occurring within striatal circuitry that are necessary to break down the habitual behaviour that leads to relapse.

  17. Cue-elicited reward-seeking requires extracellular signal-regulated kinase activation in the nucleus accumbens.

    The motivation to seek out rewards can come under the control of stimuli associated with reward delivery. The ability of cues to motivate reward-seeking behavior depends on the nucleus accumbens (NAcc). The molecular mechanisms in the NAcc that underlie the ability of a cue to motivate reward-seeking are not well understood. We examined whether extracellular signal-regulated kinase (ERK), an important intracellular signaling pathway in learning and memory, has a role in these motivational processes. We first examined p42 ERK (ERK2) activation in the NAcc after rats were trained to associate an auditory stimulus with food delivery and found that, as a consequence of training, presentation of the auditory cue itself was sufficient to increase ERK2 activation in the NAcc. To examine whether inhibition of ERK in the NAcc prevents cue-induced reward-seeking, we infused an inhibitor of ERK, U0126, into the NAcc before assessing rats' instrumental responding in the presence versus absence of the conditioned cue. We found that, whereas vehicle-infused rats showed increased instrumental responding during cue presentation, rats infused with U0126 showed a profound impairment in cue-induced instrumental responding. In contrast, intra-NAcc U0126 infusion had no effect on rats' food-reinforced instrumental responding or their ability to execute conditioned approach behavior. Our results demonstrate learning-related changes in ERK signaling in the NAcc, and that disruption of ERK activation in this structure interferes with the incentive-motivational effects of conditioned stimuli. The molecular mechanisms described here may have implications for cue-elicited drug craving after repeated exposure to drugs of abuse.

    There is growing public interest in alternative approaches to addiction treatment and scientific interest in elucidating the neurobiological underpinnings of acupuncture. Our previous studies showed that acupuncture at a specific Shenmen (HT7) points reduced dopamine (DA) release in the nucleus accumbens (NAc) induced by drugs of abuse. The present study was carried out to evaluate the effects of HT7 acupuncture on γ-aminobutyric acid (GABA) neuronal activity in the ventral tegmental area (VTA) and the reinstatement of cocaine-seeking behavior. Using microdialysis and in vivo single-unit electrophysiology, we evaluated the effects of HT7 acupuncture on VTA GABA and NAc DA release and VTA GABA neuronal activity in rats. Using a within-session reinstatement paradigm in rats self-administering cocaine, we evaluated the effects of HT7 stimulation on cocaine-primed reinstatement. Acupuncture at HT7 significantly reduced cocaine suppression of GABA release and GABA neuron firing rates in the VTA. HT7 acupuncture attenuated cocaine-primed reinstatement, which was blocked by VTA infusions of the selective GABAB receptor antagonist 2-hydroxysaclofen. HT7 stimulation significantly decreased acute cocaine-induced DA release in the NAc, which was also blocked by 2-hydroxysaclofen. HT7 acupuncture also attenuated cocaine-induced sensitization of extracellular DA levels in the NAc. Moreover, HT7 acupuncture reduced both locomotor activity and neuronal activation in the NAc induced by acute cocaine in a needle-penetration depth-dependent fashion. These results suggest that acupuncture may suppress cocaine-induced DA release in the NAc and cocaine-seeking behavior through activation of VTA GABA neurons. Acupuncture may be an effective therapy to reduce cocaine relapse by enhancing GABAergic inhibition in the VTA.

    Directory of Open Access Journals (Sweden)

    Olivier Esteves

    2009-08-01

    Full Text Available The outbreak of World War I in 1914 generated a massive influx of workers into the Clyde area, a hugely strategic region for heavy industry (shipyards, but also ammunition factories. This influx caused rents to rise in a certain number of districts, mostly around the factories and the shipyards. In order to protest against such grossly unfair increases, the women of Glasgow and their families decided to refuse to pay the new rents. They argued that they too contributed actively to the war effort, and that, by imposing rent hikes, the landlords of Glasgow and their factors implicitly sided with the German foe, by weakening a portion of the population so instrumental in supplying the British armed forces on the continent. After several months of actively sustained civil disobedience, Parliament passed a law that fixed rents until the end of the conflict. But in actual fact the Glasgow Rent Strikes generated certain changes that were to go way beyond the peculiar context of the Great War.

  8. A re-examination of information seeking behaviour in the context of activity theory

    Directory of Open Access Journals (Sweden)

    Wilson T.D.

    2006-01-01

    Full Text Available Introduction. Activity theory, developed in the USSR as a Marxist alternative to Western psychology, has been applied widely in educational studies and increasingly in human-computer interaction research. Argument. The key elements of activity theory, Motivation, Goal, Activity, Tools, Object, Outcome, Rules, Community and Division of labour are all directly applicable to the conduct of information behaviour research. An activity-theoretical approach to information behaviour research would provide a sound basis for the elaboration of contextual issues, for the discovering of organizational and other contradictions that affect information behaviour. It may be used to aid the design and analysis of investigations. Elaboration. The basic ideas of activity theory are outlined and an attempt is made to harmonize different perspectives. A contrast is made between an activity system perspective and an activity process perspective and a diagrammatic representation of the process perspective is offered. Conclusion. Activity theory is not a predictive theory but a conceptual framework within which different theoretical perspectives may be employed. Typically, it is suggested that several methods of data collection should be employed and that the time frame for investigation should be long enough for the full range of contextual issues to emerge. Activity theory offers not only a useful conceptual framework, but also a coherent terminology to be shared by researchers, and a rapidly developing body of literature in associated disciplines.

    The European Union Emissions Trading Scheme (EU ETS) has imposed a price on the allowances for CO{sub 2} emissions of electricity companies. Integrating this allowance price into the price of electricity earns a rent for companies who have received these allowances for free. During Phase I, 2005-2007, rents corresponding to the aggregate value of allocated allowances amounted to roughly EUR 13 billion per year. However, due to the specific price-setting mechanism in electricity markets true rents were considerably higher. This is due to the fact that companies also that have not received any allowances gain additional infra-marginal rents to the extent that their variable costs are below the new market price after inclusion of the allowance price. Producers with low carbon emissions and low marginal costs thus also benefit substantially from carbon pricing. This paper develops a methodology to determine the specific interaction of the imposition of such a CO{sub 2} constraint and the price-setting mechanism in the electricity sector under the assumption of marginal cost pricing in a liberalized European electricity market. The article thus provides an empirical estimate of the true total rents of power producers during Phase I of the EU-ETS (2005-2007). The EU ETS generated in Phase I additional rents in excess of EUR 19 billion per year for electricity producers. These transfers are distributed very unevenly between different electricity producers. In a second step, the paper assesses the impact of switching from free allocation to an auctioning of allowances in 2013. We show that such a switch to auctioning will continue to create additional infra-marginal rents for certain producers and will leave the electricity sector as a whole better off than before the introduction of the EU ETS.

    Full Text Available Abstract Background Sensation seeking tendencies tend to manifest during adolescence and are associated with both health-compromising behaviors and health-enhancing behaviors. The purpose of this study is to evaluate the relationship between sensation seeking and physical activity, a health-enhancing behavior, and between sensation seeking and experimenting with cigarettes, a health compromising-behavior, among a cohort of Mexican origin adolescents residing in the United States with different levels of acculturation. Methods In 2009, 1,154 Mexican origin youth (50.5% girls, mean age 14.3 years (SD = 1.04 provided data on smoking behavior, physical activity, linguistic acculturation, and sensation seeking. We conducted Pearson’s χ2 tests to examine the associations between categorical demographic characteristics (i.e. gender, age, country of birth and parental educational attainment and both cigarette experimentation and physical activity and Student’s t-tests to examine mean differences on the continuous variables (i.e. sensation seeking subscale by the behaviors. We examined mean differences in the demographic characteristics, acculturation, and both behaviors for each of the sensation seeking subscales using analysis of variance (ANOVA. To examine relationships between the sensation seeking subscales, gender, and both behaviors, at different levels of acculturation we completed unconditional logistic regression analyses stratified by level of acculturation. Results Overall, 23.3% had experimented with cigarettes and 29.0% reported being physically active for at least 60 minutes/day on at least 5 days/week. Experimenting with cigarettes and being physically active were more prevalent among boys than girls. Among girls, higher levels of sensation seeking tendencies were associated with higher levels of acculturation and experimentation with cigarettes, but not with physical activity. Among boys, higher levels of sensation seeking

  16. Hide and Seek: Radial-velocity searches for planets around active stars

    The ultimate obstacle to determining the masses of small, rocky exoplanets through radial-velocity (RV) monitoring is the intrinsic variability of the host stars themselves. For my PhD, I developed an intuitive and robust data analysis framework in which the activity-induced variations are modelled with a Gaussian process that has the frequency structure of the stellar magnetic activity. This allowed me to determine precise and accurate masses of the planets in the CoRoT-7, Kepler-78 and Kepler-10 systems. In parallel, I explored the physical origin of activity-induced RV variations of our best-known star: the Sun. I conducted the first systematic RV campaign of the Sun seen as an exoplanet host star using the 3.6m/HARPS spectrograph, by observing sunlight reflected off the bright asteroid 4/Vesta. I used images from the Solar Dynamics Observatory to reconstruct the RV signals incurred by individual surface features such as sunspots, faculae and granulation. I found that the activity-induced RV variations are driven by the suppression of convective blueshift arising dominantly from the presence of faculae. I also identified the full-disc magnetic flux as an excellent proxy for activity-induced RV variations.I am now pursuing my solar investigations using Sun-as-a-star RV observations acquired with the new solar telescope feed at HARPS-N. In particular, I am investigating the impact of magnetic surface features on the shapes of the spectral line profiles, rather than on the RVs themselves (which are a single moment of these lines). This work is key to developing physically-driven, better-tailored models for activity-induced RV variations, in preparation for the potentially habitable, Earth-like planets to be discovered and characterised in the coming years with TESS and GMT/G-CLEF.This work was funded by the Science and Technology Facilities Council in the United Kingdom and the John Templeton Foundation.

    Forming and breaking associations between emotionally salient environmental stimuli and rewarding or aversive outcomes is an essential component of learned adaptive behavior. Importantly, when cue-reward contingencies degrade, animals must exhibit behavioral flexibility to extinguish prior learned associations. Understanding the specific neural circuit mechanisms that operate during the formation and extinction of conditioned behaviors is critical because dysregulation of these neural processes is hypothesized to underlie many of the maladaptive and pathological behaviors observed in various neuropsychiatric disorders in humans. The medial prefrontal cortex (mPFC) participates in the behavioral adaptations seen in both appetitive and aversive-cue-mediated responding, but the precise cell types and circuit mechanisms sufficient for driving these complex behavioral states remain largely unspecified. Here, we recorded and manipulated the activity of parvalbumin-positive fast spiking interneurons (PV+ FSIs) in the prelimbic area (PrL) of the mPFC in mice. In vivo photostimulation of PV+ FSIs resulted in a net inhibition of PrL neurons, providing a circuit blueprint for behavioral manipulations. Photostimulation of mPFC PV+ cells did not alter anticipatory or consummatory licking behavior during reinforced training sessions. However, optical activation of these inhibitory interneurons to cues associated with reward significantly accelerated the extinction of behavior during non-reinforced test sessions. These data suggest that suppression of excitatory mPFC networks via increased activity of PV+ FSIs may enhance reward-related behavioral flexibility.

    Since the discovery of the transiting super-Earth CoRoT-7b, several investigations have yielded different results for the number and masses of planets present in the system, mainly owing to the star's high level of activity. We re-observed CoRoT-7 in January 2012 with both HARPS and CoRoT, so that we now have the benefit of simultaneous radial-velocity and photometric data. This allows us to use the off-transit variations in the star's light curve to estimate the radial-velocity variations induced by the suppression of convective blueshift and the flux blocked by starspots. To account for activity-related effects in the radial-velocities which do not have a photometric signature, we also include an additional activity term in the radial-velocity model, which we treat as a Gaussian process with the same covariance properties (and hence the same frequency structure) as the light curve. Our model was incorporated into a Monte Carlo Markov Chain in order to make a precise determination of the orbits of CoRoT-7b a...

    Using a new model of markets in regulated open access resources, we illustrate the evolution of a fishery as demand for the product grows. We show that increased demand for fish in its fresh form shortens the fishing season and leads to the development of a market for processed fish. The model allows us to calculate the rent gains from rationalizing the fishery, and we show that much of the rent gains come on the market side as the season lengthens and more fish can be delivered to the higher...

    To address the severity of erectile dysfunction (ED) in consecutive sexually active men seeking a prostate health screening through a multivariable risk stratification including comorbidities and lower urinary tract symptoms (LUTS). Four hundred and twenty five consecutive subjects with stable sexual relationship with normal testosterone levels were enrolled. The International Index of Erectile Function (IIEF-5) and the International Prostate Symptom Score (IPSS) questionnaires were collected and health-significant comorbidities were scored with the Charlson comorbidity index (CCI). All the independent predictors of ED were combined to form four different risk categories of ED: low (age⩽65 years and IPSS65 years, IPSS⩾8 or CCI⩾1), high (two of the following: age>65 years, IPSS⩾8 or CCI⩾1) and very high (age >65 years, IPSS⩾8 and CCI⩾1). The prevalence of ED increased with increase of CCI (χ(2) likelihood ratio: 40.85, P=0.001). The median of the IIEF-5 significantly reduced with the increase of the CCI (P<0.001) and with the worsening of our risk group stratification (P<0.001). At univariate logistic regression analysis very high risk was significantly associated with of ED (odds ratio: 26.85, P<0.001). Very high-risk group predicted ED with 88% and 56% of specificity and sensitivity, respectively. Combining these risk factors through our risk stratification may be usefulness in revealing an underling ED.

    Relapse to maladaptive eating habits during dieting is often provoked by stress and there is evidence for a role of ovarian hormones in stress responses and feeding. We studied the role of these hormones in stress-induced reinstatement of food seeking and medial prefrontal cortex (mPFC) neuronal activation in c-fos-GFP transgenic female rats, which express GFP in strongly activated neurons. Food-restricted ovariectomized or sham-operated c-fos-GFP rats were trained to lever-press for palatable food pellets. Subsequently, lever-pressing was extinguished and reinstatement of food seeking and mPFC neuronal activation was assessed after injections of the pharmacological stressor yohimbine (0.5-2 mg/kg) or pellet priming (1-4 noncontingent pellets). Estrous cycle effects on reinstatement were also assessed in wild-type rats. Yohimbine- and pellet-priming-induced reinstatement was associated with Fos and GFP induction in mPFC; both reinstatement and neuronal activation were minimally affected by ovarian hormones in both c-fos-GFP and wild-type rats. c-fos-GFP transgenic rats were then used to assess glutamatergic synaptic alterations within activated GFP-positive and nonactivated GFP-negative mPFC neurons following yohimbine-induced reinstatement of food seeking. This reinstatement was associated with reduced AMPA receptor/NMDA receptor current ratios and increased paired-pulse facilitation in activated GFP-positive but not GFP-negative neurons. While ovarian hormones do not appear to play a role in stress-induced relapse of food seeking in our rat model, this reinstatement was associated with unique synaptic alterations in strongly activated mPFC neurons. Our paper introduces the c-fos-GFP transgenic rat as a new tool to study unique synaptic changes in activated neurons during behavior.

    Health information obtained from the Internet has an impact on patient health care outcomes. There is a growing concern over the quality of online health information sources used by diabetic patients because little is known about their health information-seeking behavior and the impact this behavior has on their diabetes-related self-care, in particular in the Middle East setting. The aim of this study was to determine the online health-related information-seeking behavior among adult type 2 diabetic patients in the Middle East and the impact of their online health-related information-seeking behavior on their self-care activities. A cross-sectional survey was conducted on 344 patients with type 2 diabetes attending inpatient and outpatient primary health care clinics at 2 teaching hospitals in Riyadh, Saudi Arabia. The main outcome measures included the ability of patients to access the Internet, their ability to use the Internet to search for health-related information, and their responses to Internet searches in relation to their self-care activities. Further analysis of differences based on age, gender, sociodemographic, and diabetes-related self-care activities among online health-related information seekers and nononline health-related information seekers was conducted. Among the 344 patients, 74.1% (255/344) were male with a mean age of 53.5 (SD 13.8) years. Only 39.0% (134/344) were Internet users; 71.6% (96/134) of them used the Internet for seeking health-related information. Most participants reported that their primary source of health-related information was their physician (216/344, 62.8%) followed by television (155/344, 45.1%), family (113/344, 32.8%), newspapers (100/344, 29.1%), and the Internet (96/344, 27.9%). Primary topics participants searched for were therapeutic diet for diabetes (55/96, 57%) and symptoms of diabetes (52/96, 54%) followed by diabetes treatment (50/96, 52%).

Land rent taxation is high cost mode of financing central administration in a tax incidence sense. Participatory administration by the governed is a lower cost alternative. We speculate why the low cost option has been out-competed by its higher cost alternative throughout history. We also take up constraints on predation on farmers by a landlord at the center.

    Chicago and its suburbs are experiencing an increasing demand for water from a growing population and economy and may experience water scarcity in the near future. The Chicago metropolitan area has nearly depleted its groundwater resources to a point where interstate conflicts with Wisconsin could accompany an increased reliance on those sources. Further, the withdrawals from Lake Michigan is limited by the Supreme Court decree. The growing demand and indications of possible scarcity suggest a need to reexamine the pricing policies and the dynamics of demand. The study analyses the demand for water and develops estimates of scarcity rents for water in Chicago. The price and income elasticities computed at the means are -0.002 and 0.0002 respectively. The estimated scarcity rents ranges from $0.98 to $1.17 per thousand gallons. The results indicate that the current prices do not fully account for the scarcity rents and suggest a current rate with in the range $1.53 to $1.72 per thousand gallons.

    Full Text Available Występowanie rent gruntowych we współczesnym rolnictwie UE potwierdza wieloletni rosnący trend cen ziemi rolniczej. Nasuwa się jednak pytanie, czy są to przede wszystkim renty różniczkowe związane z różną wydajnością gruntów rolnych, czy renty absolutne w klasycznym rozumieniu, czy też renty polityczne w ujęciu teorii wyboru publicznego? Cele artykułu mają przede wszystkim wymiar teoriopoznawczy. Podjęto w nim próbę weryfi kacji koncepcji renty gruntowej, którą sformułowano na podstawie badań przeprowadzonych w Polsce. Tym razem jednak zakres badań obejmuje pełen przekrój struktur agrarnych UE. Według wspomnianej koncepcji źródłem współczesnej renty gruntowej jest wyższa oczekiwana produktywność kapitału w rolnictwie niż w jego otoczeniu rynkowym. Często tłumaczy się to zjawisko wypłacaniem rent politycznych w ramach WPR. Czy tak jest w istocie ? Przeprowadzone badania odpowiadają m.in. na pytanie w jakich krajach i strukturach agrarnych ewentualna różnica wspomnianej produktywności kapitału jest największa i na ile wynika to z rent politycznych, a na ile z innych czynników?

We studied the role of these hormones in stress-induced reinstatement of food seeking and medial prefrontal cortex (mPFC) neuronal activation in c-fos-GFP transgenic female rats, which express green fluorescent protein (GFP) in strongly activated neurons. Food-restricted ovariectomized or sham-operated c-fos-GFP rats were trained...

    Yanase Pharmacy Co., Ltd. actively provides home health care intervention. The present study examined the effects of drug management guidance provided as home-visit-based health care support for elderly patients living in rented housing. The subjects were 117 patients who moved into rented accommodation for the elderly between June 2009 and February 2012, and who received drug administration guidance. The majority of the subjects had intractable diseases: 74(63%)were terminally ill with cancer, 7(6%)had amyotrophic lateral sclerosis, and 2(2%)had muscular dystrophy. Home-visit-based support included accompanying physicians' visits, formulation support, participation in the conference, and the provision of drug information for home-visiting nurses. The following formulation support measures were used: reducing intravenous infusion was proposed to address terminally ill cancer patients with a large amount of sputum; advice was provided on the selection of opioids for patients with renal failure; and drug options were discussed to alleviate the symptoms of gastrointestinal obstruction. All of these measures effectively alleviated symptoms.

  7. Rent, Lease or Buy: Randomized Algorithms for Multislope Ski Rental

    CERN Document Server

    Lotker, Zvi; Rawitz, Dror

    2008-01-01

    In the Multislope Ski Rental problem, the user needs a certain resource for some unknown period of time. To use the resource, the user must subscribe to one of several options, each of which consists of a one-time setup cost (``buying price''), and cost proportional to the duration of the usage (``rental rate''). The larger the price, the smaller the rent. The actual usage time is determined by an adversary, and the goal of an algorithm is to minimize the cost by choosing the best option at any point in time. Multislope Ski Rental is a natural generalization of the classical Ski Rental problem (where the only options are pure rent and pure buy), which is one of the fundamental problems of online computation. The Multislope Ski Rental problem is an abstraction of many problems where online decisions cannot be modeled by just two options, e.g., power management in systems which can be shut down in parts. In this paper we study randomized algorithms for Multislope Ski Rental. Our results include the best possibl...

  8. The land rent category in mainstream economics and its contemporary applications

    Directory of Open Access Journals (Sweden)

    Bazyli Czyżewski

    2009-01-01

    Full Text Available The economic globalisation process makes the economic factors rotate faster. As a result the value added is intercepted by market mechanism and transferred to the economically stronger entities. That process concerns especially agriculture. There exists a crucial question whether an agricultural land factor is still capable to generate economic rents which would be the determinants of comparative advantages? On the one hand, D. Ricardo’s land rents are vanishing, H. George’s rents are provoking financial crisis, monetarists assumptions are becoming unsufficient, on the other, the land factor gains new environmental applications and there is still a hope that land rents have its origins in a real value. This paper aims at presenting the evolution of the land rents theory starting from classical economics. The author makes an attempt to answer the question if the land rent theories are still relevant and how land rent category can be implemented in agricul-tural policy of the UE? One formulates a hypothesis that the neoclassical theory of rent usually presented in economic textbooks is insufficient to describe reality reducing the sources of land rent to a low land supply flexibility and treating that as constant variable in economic models.

    Ecological land rent is the excess profit produced by resource scarcity,and is also an important indicator for measuring the social and economic effects of resource scarcity.This paper,by calculating the respective ecological land rents of all the provinces in China for the years 2002 and 2007,and with the assistance of the software programs ArcGIS and GeoDA,analyzes the spatial differentiation characteristics of ecological land rent; then,the influencing factors of ecological land rent differentiation among the provinces are examined using the methods of traditional regression and spatial correlation analysis.The following results were obtained:First,ecological land rent per unit of output in China shows stable distribution characteristics of being low in the southwestern and northeastern provinces,and high in Hebei and Henan provinces.There is also an increasing tendency in the central and western provinces,and a decreasing one in the eastern provinces.In general,the spatial distribution of ecological land rent per unit of output in China is quite scattered.Second,the total ecological land rent shows significant spatial aggregation characteristics,in particular the provinces in China possessing high total amounts of ecological land rent tend to be adjacent to one another,as do those with low total amounts,and the spatial difference characteristics of the eastern,central and western provinces are distinguished.The Bohai Rim,Yangtze River Delta and Pearl River Delta are shown to be highly clustering regions of total ecological land rent,while the western provinces have very low ecological land rent in terms of total amount.Third,population distribution,economic level and industrial structure were all important influencing factors influencing ecological land rent differentiation among provinces in China.Furthermore,population density,urbanization level,economic density,per capita consumption level and GDP per capita were all shown to be positively related to total

    Full Text Available Empirical evidence has established the association between rent control and crises such as oil and World wars; yet the Jamaican governments have not reintroduced rent control and updated the Rent Restriction Act despite global recession, oil and food crises and increased poverty. The objectives of this work are: 1 To conduct a documentary analysis of prior research on the extent of the problem, and these will provide an understanding and a content for the current work; 2 To identify the issues/concerns of the Rent Restriction Act; 3 To assess the issues/concerns of the Rent Restriction Act, and 4 Drawing on the knowledge of Rent Restriction Act, recommend policies or measures that can be instituted to address changes in the framework in Jamaica. The current work used mixed method approach, phenomenology and survey research. Landlords indicated that they had more right than for tenants; their complaints were the non-payment of rent; were more knowledge of Rent Restriction Act than the tenants and the majority of them did not answer the question on “Have you ever had a case where the Act was referred to?” Two times more males were knowledge about the Rent Restriction Act than that of female; more males indicated that they had rights than that of females, less females’ problem was harassment than that of males; more males gave the Rent Restriction Act a good rating compared to females and 3.5 times more males believed that the Rent Restriction Act was relevant in contemporary Jamaica. The findings provide understanding of the issues, and can be used to aid policy formulation.

  11. International Product Market Integration, Rents and Wage Formation

    DEFF Research Database (Denmark)

    Sørensen, Allan

    International product market integration enhances both export possibilities through easier access to foreign markets, but also the import threat arising from foreign firms penetrating into the domestic market. These mechanisms affect wage formation and employment creation through many channels...... including product market rents and the possibility that jobs may be relocated across national labour markets. Possibilities and threats, however, will not in general be uniformly distributed across firms and therefore groups in the labour market. These issues are explored in a Ricardian trade model...... with imperfect competition, heterogeneity in the labour market, and decentralized wage-bargaining. The Paper analyses how product market integration affects wage formation, and identifies characteristics of winners and losers in the integration process....

  12. Intergenerational equity and the investing of rents from exhaustible resources

    Energy Technology Data Exchange (ETDEWEB)

    Hartwick, J.M.

    1977-12-01

    The present generation's ethical dilemma over shortchanging future generations by overconsuming exhaustible resources could be relieved by a program of converting the capital from these resources into machines and living off the current flow of machines and labor. If the stock of machines is assumed not to depreciate, then the stock of productive capital and resources is not depleted. Cobb-Douglas technology is used to determine what will happen to consumption if only the rents from exhaustible resources are invested in reproducible capital goods. An important feature of Cobb-Douglas technology is that input in the form of minerals from an exhaustible resource is needed to get a positive output of the single produced commodity. Results of the model indicate that a savings investment rule will not provide for the maintenance of per capita consumption constant over time. Further studies have explored the effects of depreciations and intergenerational equity. 7 references.

  20. Is There Rent Sharing in Italy? Evidence from Employer-Employee Data

    Directory of Open Access Journals (Sweden)

    Alessia Matano

    2011-12-01

    Full Text Available Using a unique employer-employee panel database, we investigate the extent of rent sharing in Italy from 1996 to 2003. We derive the following findings. First, after controlling for the national bargaining level, there is robust evidence of rent sharing at firm level. Second, by means of fixed effects estimates we show that the sorting of high-ability workers into high-profit firms appears to play a substantial role, since it captures a significant amount of cross sectional estimates of rent sharing. Third, in accordance to the related literature the endogeneity of profits causes a severe underestimation of rent sharing. Our final IV estimate of the elasticity of wages with respect to profits per employee amounts to 6%, with a "Lester" range of 24%. Moreover, we point out that the impact of rent sharing is not homogeneous across several dimensions (gender, occupation, sector and macroarea.

  2. Host-seeking activity and avian host preferences of mosquitoes associated with West Nile virus transmission in the northeastern U.S.A.

    2010-01-01

    Mosquito host-seeking activity was studied using a custom-designed trap to explore: (1) at which time interval of the night adult mosquito abatement would be most effective, and (2) if there exists an avian-specific host-seeking preference. Overnight trials using traps baited with dry ice showed that Aedes taeniorhynchus (Wiedemann) was most active at dusk and was then captured throughout the night. In contrast, Culex spp. (Cx. pipiens (Linnaeus) and Cx. restuans (Theobald) delayed most activity until about two h after dusk and were then captured through the night. This pattern suggests that management activities directed at adult Culex spp. would be most effective if initiated well after sunset. Mosquito capture rates in traps baited with birds in net bags were significantly greater than those with empty net bags, indicating that mosquitoes were attracted to the birds and not incidentally being sucked in by the custom trap's strong fan motor (Wilcoxon matched-pairs signed-ranks test, n = 24, t = 30, p 2 = 0.21, p = 0.02). Trials with paired traps that contained different native bird species showed that Gray Catbirds, Dumatella carolinensis, attracted more mosquitoes than the heavier Northern Cardinals, Cardinalis cardinalis (paired samples t-test, t = 2.58, df = 7, p = 0.04). However, attractiveness did not differ substantially among bird species, and Gray Catbirds did not attract more mosquitoes than all other birds combined as a group. American Robins, Turdus migratorius (n = 4) were comparable in attractiveness to other bird species, but not enough American Robins were captured for a comprehensive study of mosquito avian preference.

  3. Activation of pyramidal neurons in mouse medial prefrontal cortex enhances food seeking behavior while reducing impulsivity in the absence of an effect on food intake

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available The medial prefrontal cortex (mPFC is involved in a wide range of executive cognitive functions, including reward evaluation, decision-making, memory extinction, mood, and task switching. Manipulation of the mPFC has been shown to alter food intake and food reward valuation, but whether exclusive stimulation of mPFC pyramidal neurons, which form the principle output of the mPFC, is sufficient to mediate food rewarded instrumental behavior is unknown. We sought to determine the behavioral consequences of manipulating mPFC output by exciting pyramidal neurons in mouse mPFC during performance of a panel of behavioral assays, focusing on food reward. We found that increasing mPFC pyramidal cell output using Designer Receptors Exclusively Activated by Designer Drugs (DREADD enhanced performance in instrumental food reward assays that assess food seeking behavior, while sparing effects in affect and food intake. Specifically, activation of mPFC pyramidal neurons enhanced operant responding for food reward, reinstatement of palatable food seeking, and suppression of impulsive responding for food reward. Conversely, activation of mPFC pyramidal neurons had no effect on unconditioned food intake, social interaction, or behavior in an open field. Furthermore, we found that behavioral outcome is influenced by the degree of mPFC activation, with a low drive sufficient to enhance operant responding and a higher drive required to alter impulsivity. Additionally, we provide data demonstrating that DREADD stimulation involves a nitric oxide synthase dependent pathway, similar to endogenous muscarinic M3 receptor stimulation, a finding that provides novel mechanistic insight into an increasingly widespread method of remote neuronal control.

    This study sought to define the attributes and practices of organized fossil groups (e.g., clubs, paleontological societies) as amateur paleontologists, as well as those of professional paleontologists, and explore the potential for these two groups to work collaboratively as a formalized community. Such an investigation is necessary to develop design principles for an online environment that supports this community and encourages communication and shared practice among individuals with different backgrounds in paleontology and who are geographically isolated. A national survey of fossil group representatives and professional paleontologists was used to address the research questions. The results provide a rich description of the attributes and activities of both groups and are discussed in terms of three design principles for supporting the two groups in a form of collaboration and fellowship via a coherent shared practice within an online learning community.

    Directory of Open Access Journals (Sweden)

    Hartmut Elsenhans

    2009-04-01

    Full Text Available Rents are a basic element of the political economy of underdeveloped economies. They hinder and often block the mechanism of social integration through gainful employment and veto the power of labour, which characterizes capitalist societies and the constitution of citizenship. The impact of rent on political structures is, however, ambiguous. Anomie is only one possible result. Hence the link between raw material exports and non-state violence is also ambiguous. Many societies, which are characterized by rents, have developed quite powerful mechanisms of keeping internal peace, possibly with limited participation. The conditions of differential impacts of rent on social structures and political behaviour call for an analysis of internal interest mediation.

    2006-01-01

    Full Text Available Introduction. The article argues for a closer association between information seeking research and the practices of teaching information seeking. Findings are presented from a research project on information seeking, didactics and learning (IDOL investigating librarians' and teachers' experiences of teaching information seeking. Method. Thirteen teachers and five librarians, teaching 12-19 year-old students in three schools, participated. Forty-five interviews were conducted over a period of three years. Analysis. The IDOL project adopted a phenomenographic approach with the purpose of describing patterns of variation in experiences. The findings were also analysed by way of relating them to four competing approaches to the mediation of information literacy. Results. A gap was identified between experiences of teaching content that focused on sources and order, and experiences of assessment criteria applied to students' work that focused on the importance of correct facts and the analysis of information. These findings indicate a highly restricted range of teaching contents when compared with the four theoretical approaches to the mediation of information literacy. Conclusion. Teaching information seeking might be enhanced by a wider repertoire of contents reflecting more varied theoretical understanding developed in information seeking research, particularly as regards the importance of content and context related to user perspectives.

    2015-06-01

    Full Text Available The present paper aims to demonstrate the role that ground rent has in establishing the agricultural land price. In order to be able to prove the connection between the ground rent and the agricultural land price, there are submitted to debate indicators that are part of ground rent such as the positioning of the land, the distance between the land and the access roads and water source, the intrinsic qualities of the land soil, the type of land and the manner of exploitation. The debate is intended to show how and in what manner the indicators part of ground rent may influence the price of an agricultural land. The final purpose of this study is to prove that a justified land price may contribute to encourage the agricultural land transactions and therefore to develop the land market. To fulfil the purpose of this paper it is necessary to understand what land ground means, why it is important the land price and how can the agricultural land price influence the agricultural land market and the development of the agriculture overall. The main methods utilized are collecting, analyze and interpreting data and information from the specialized literature. The conclusions formulated at the end of the study allow seeing the influence of ground rent on agricultural land price, the influence of the agricultural land price on agricultural land market and the influence of agricultural land market on the development of the agriculture.

  20. Rent taxation and its intertemporal effects in a small open economy

    DEFF Research Database (Denmark)

    Köthenbürger, Marko; Poutvaara, Panu

    2009-01-01

    Previous literature concludes that replacing wage taxation by taxes on a fixed factor or its rents benefits future generations. However, the effects of such steady-state gains on the transition generations have been left open. In this paper, we show that taxation of rents may also increase utilit...... of the current generation provided tax revenues are earmarked to reduce wage taxes. In particular, a shift in the tax mix may yield an intergenerational Pareto-improvement when the initially prevailing tax mix is sufficiently skewed toward wage taxation....

  1. Capital switching and the role of ground rent: 2 Switching between circuits and switching between submarkets

    OpenAIRE

    R J King

    1989-01-01

    In the first paper of this series of three, Harvey's 'circuits of capital' argument was discussed, and was linked first to ground rent theory, and second to forms of social change and crisis in advanced, Western-style economies. In the present paper these various theoretical insights are used to reflect upon the urban housing market in Melbourne from the 1930s to the 1980s. It is concluded (1) that average rent (average annual cost relative to wages), and thereby housing-related accumulation,...

  2. The effects of tax competition when politicians create rents to buy political support

    DEFF Research Database (Denmark)

    Eggert, Wolfgang; Sørensen, Peter Birch

    2008-01-01

    We set up a probabilistic voting model to explore the hypothesis that tax competition improves public sector efficiency and social welfare. In the absence of tax base mobility, distortions in the political process induce vote-maximising politicians to create rents to public sector employees....... Allowing tax base mobility may be welfare-enhancing up to a point, because the ensuing tax competition will reduce rents. However, if tax competition is carried too far, it will reduce welfare by causing an underprovision of public goods. Starting from an equilibrium where tax competition has eliminated...

    Full Text Available Researchers have determined that real estate prices vary in continuous ways as a function of spatial characteristics.  In this study we examine whether geographically weighted regression (GWR provides different estimates of price effects around a sports stadium than more traditional regression techniques.  We find that an application of GWR with hedonic prices finds that the stadium has a negative external effect on housing rents that extends outward 560 meters, in contrast to the positive external effect on housing rents found using a conventional estimation technique.

  4. Finding Good Areas for Renting Apartments Using Apartments Information and Users' Trajectories

    Si, R.; Lu, M.; Arikawa, M.; Asami, Y.; Iwasaki, J.

    2014-04-01

    Current apartment renting web sites provide services to search apartments by attribute filters while they lack the services to help find areas that are convenient for living and meet customers' personal preference. In many cases, people not only need attributes of the apartments meeting their requirements, but also need the attributes of the area be satisfied. We propose an IT service that can find appropriate areas for customers to rent apartments while they want to move to new places. The areas are picked according to users' life styles mined from their former moving trajectories and to the attributes of the areas calculated from preferences of present rooms of users.

  5. THE BUBONIC PLAGUE OF 1349, THE WAGE-TO-RENT RATIO, AND THE ENGLISH PEASANT FAMILY

    Directory of Open Access Journals (Sweden)

    Stephanie O. Crofton

    2005-01-01

    Full Text Available The bubonic plague that swept England in 1349 provides an example of how changes in economic conditions can change norms of social behavior. The death of almost 50 percent of the population altered the returns to labor and land. As the demand for land and the supply of labor declined, rents fell and wages rose. This increased wage-to-rent ratio shifted the structure of the economy from household production to market production. In turn, these changes affected migration, family and community ties, women s labor force participation, family size, inheritance customs, the status of landowning widows, and care for the elderly.

    Ease in finding the configuration at the global energy minimum in a symmetric neural network is important for combinatorial optimization problems. We carry out a comprehensive survey of available strategies for seeking global minima by comparing their performances in the binary representation problem. We recall our previous comparison of steepest descent with analog dynamics, genetic hill-climbing, simulated diffusion, simulated annealing, threshold accepting and simulated tunneling. To this, we add comparisons to other strategies including taboo search and one with field-ordered updating.

    Sensation seeking leads to violence—runs an influential hypothesis in the social scientific study of violent behavior. Although studies confirm that violence is sometimes structured by sensation-seeking motives, the literature seldom comments on the limits to this explanation of violence....... The present study examines the scale of violence motivated by sensation seeking and the degree to which there are several distinct forms of sensation seeking motives operative in violence, rather than a sensation-seeking motive in the singular. The study draws on a sample of situations from Copenhagen...... involving street violence, which are coded quantitatively and qualitatively. Our analysis shows that sensation seeking only seldom seems to play a role in the structuring of street violence. Moreover, the data indicate that sensation seeking finds expression in street violence situations in two different...

    2015-01-01

    Full Text Available Nowadays, leasing has become an increasingly important and popular method for equipment acquisition. But, because of the rent pricing difficulties and some risks that affect the lessor and lessee's decision making, there are many people that still tend to buy equipment instead of lease it. In this paper we explore how risk can affect the leasing issue support mathematical model. For this purpose, we consider three types of risk; Credit risk, Transaction risk and Risk based pricing. In particular, our focus was on how to make decision about rent pricing in a leasing problem with different customers, various quality levels and different pricing methods. Finally, the mathematical model has been solved by Genetic Algorithm that is a search heuristic to optimize the problem. This algorithm was coded in MATLAB® R2012a to provide the best set of results.

  3. The NBA’s Maximum Player Salary and the Distribution of Player Rents

    Directory of Open Access Journals (Sweden)

    Kelly M. Hastings

    2015-03-01

    Full Text Available The NBA’s 1999 Collective Bargaining Agreement (CBA included provisions capping individual player pay in addition to team payrolls. This study examines the effect the NBA’s maximum player salary on player rents by comparing player pay from the 1997–1998 and 2003–2004 seasons while controlling for player productivity and other factors related to player pay. The results indicate a large increase in the pay received by teams’ second highest and, to a lesser extent, third highest paid players. We interpret this result as evidence that the adoption of the maximum player salary shifted rents from stars to complementary players. We also show that the 1999 CBA’s rookie contract provisions reduced salaries of early career players.

    2003-01-01

    SUMMARY Understanding the mental health needs of lesbian and bisexual (sexual minority) women is an integral part of designing and providing appropriate mental health services and treatment for them. In an effort to understand the mental health needs of sexual minority women who seek community treatment, a chart review was conducted of the 223 lesbian and bisexual women who presented for services between July 1, 1997 and December 31, 2000 at Fenway Community Health in Boston, MA. Data are based on clients' self-reports and clinician assessments of clients' presenting problem, relevant developmental history, prior mental health and substance abuse treatment, current reports of emotional/psychological symptoms, and areas of impaired functioning. Although substance abuse and suicidal ideation were commonly reported problems, other concerns were more frequently reported. High percentages of lesbians and bisexual women reported relationship concerns and lack of adequate social networks; rates of depression and anxiety based on clinicians' assessments were also high. Overall, lesbians and bisexual women did not differ in the issues they brought to treatment or level or types of impairment. Compared with previous community survey samples, however, study participants appeared to be healthier than general, non-clinical samples of self-identified lesbians, possibly reflecting the special characteristics of sexual minority women who seek treatment in specialized community sites such as the Fenway. Although patients who come to these sites may not represent the more general population of sexual minority women, community health centers known to serve lesbian, gay, bisexual and transgender (LGBT) individuals may be fruitful access points for studying the mental health status and treatment needs of sexual minority women.

    DAI Teqi; WANG Liang; ZHOU Binxue

    2016-01-01

    China is experiencing rapid urbanization and motorization.Urban transport congestion poses a challenge to the cities of China.Policies have been made trying to control the car use and the land use in Chinese cities without sound modelling researches.The existing literature on monocentric city modelling has shown that the parameters are critical for the outcome of the modelling.Following the Alonso-type monocentric model,this paper introduces a bi-modal model to simulate the city size,the distribution of land rent and the modal substitution in Chinese cities.We set the key parameters according to the recent available data of China's cities,and re-explain the hypothesis of the model.Then we make a sensitivity analysis to reveal the impacts of key parameters on the Chinese cities.According to the results,we find that the wage,the price of car use and the agriculture rent have significant impacts on city size.The land supply for the private transport or the public transport has the strongest impacts on car use and the level of transport congestion.The total population of the city and the wage level have strong impacts on land rent.Some results are counter-intuitive,but explainable.We also discuss implication of these results for policy making.

    Science.gov (United States)

    Bleakley, Amy; Hennessy, Michael; Fishbein, Martin

    2011-07-01

    This article reports on the extent to which adolescents report actively seeking sexual content in media, identifies from which media they report seeking, estimates the association between seeking sexual information and romantic and sexual behavior, and shows that active seeking of sexual content in media sources is explained by an intention to seek such content using the Integrative Model of Behavioral Prediction, a reasoned action approach. The data are a national sample of 810 adolescents aged 13 to 18 years. Results show that 50% of adolescents reported actively seeking sexual content in their media choices, which included movies, television, music, Internet pornography sites, and magazines. Males sought sex content more than females, and gender differences were greatest for seeking from Internet pornography sites, movies, and television. Path analysis demonstrate that seeking sexual content is well-predicted by intentions to seek, and intentions are primarily driven by perceived normative pressure to seek sexual content.

  12. Suppressing effect of saikosaponin A, an active ingredient of Bupleurum falcatum, on chocolate self-administration and reinstatement of chocolate seeking in rats.

    2017-01-18

    Recent lines of experimental evidence have indicated that saikosaponin A (SSA) - a bioactive ingredient of the medicinal plant, Bupleurum falcatum L. - suppressed alcohol, morphine, and cocaine self-administration in rats. The present paper was designed to assess whether the protective properties of SSA on addiction-related behaviors generalize to a hyperpalatable food such as a chocolate-flavored beverage (CFB). To this end, rats were initially trained to lever-respond for CFB [5% (w/v) Nesquik(®) powder in water] under fixed ratio (FR) 10 (FR10) schedule of reinforcement. Once lever-responding reached stable levels, rats were treated acutely with two different dose ranges of SSA (0, 0.25, 0.5, and 1mg/kg; 0, 1, 2.5, and 5mg/kg; i.p.) and exposed to the FR10 and progressive ratio (PR) schedules of reinforcement in four independent experiments. The effect of acutely administered SSA (0, 0.25, 0.5, and 1mg/kg; i.p.) on cue-induced reinstatement of seeking behavior for CFB was also assessed. Under the FR and PR schedules of reinforcement, treatment with SSA diminished lever-responding for CFB, amount of self-administered CFB, and breakpoint for CFB. All variables were virtually completely suppressed after treatment with 5mg/kg SSA. Treatment with SSA also suppressed reinstatement of CFB-seeking behavior. No dose of SSA altered rat motor-performance, evaluated exposing all rats to an inverted screen test immediately after the self-administration session. These results demonstrate that acute treatment with SSA potently suppressed several addictive-like behaviors motivated by highly hedonic nourishment. These data extend to a highly rewarding natural stimulus the anti-addictive properties of SSA recently disclosed in rats self-administering alcohol, morphine, and cocaine.

    2010-09-01

    The metabotropic glutamate receptor 7 (mGluR7) has been reported to be involved in cocaine and alcohol self-administration. However, the role of mGluR7 in relapse to drug seeking is unknown. Using a rat relapse model, we found that systemic administration of AMN082, a selective mGluR7 allosteric agonist, dose-dependently inhibits cocaine-induced reinstatement of drug-seeking behavior. Intracranial microinjections of AMN082 into the nucleus accumbens (NAc) or ventral pallidum, but not the dorsal striatum, also inhibited cocaine-primed reinstatement, an effect that was blocked by local co-administration of MMPIP, a selective mGluR7 antagonist. In vivo microdialysis demonstrated that cocaine priming significantly increased extracellular dopamine in the NAc, ventral pallidum and dorsal striatum, while increasing extracellular glutamate in the NAc only. AMN082 alone failed to alter extracellular dopamine, but produced a slow-onset long-lasting increase in extracellular glutamate in the NAc only. Pre-treatment with AMN082 dose-dependently blocked both cocaine-enhanced NAc glutamate and cocaine-induced reinstatement, an effect that was blocked by MMPIP or LY341497 (a selective mGluR2/3 antagonist). These data suggest that mGluR7 activation inhibits cocaine-induced reinstatement of drug-seeking behavior by a glutamate-mGluR2/3 mechanism in the NAc. The present findings support the potential use of mGluR7 agonists for the treatment of cocaine addiction.

    This paper examines the problem of hold-up in the agri-food sector. Production contracts offered to future Danish Broiler producers give rise to specific investments and appropriable quasi rents. Farmers are vulnerable to opportunistic behaviour by poultry processors which materializes in lower......, when building the broiler house, to prepare a viable future change in production from broilers to pigs.

    China’s traditional urban land system is established in highly centralized planned economy. This system negates functions of value law and economic law fundamentally,so it is not favorable for establishment of market mechanism and development of market economy. This study took Marx’s ground rent theory as guidance,combined existing problems of China’s land use system,and made analysis on innovation of China’s urban land system from property right system,land market and land price.

    Full Text Available The study was carried out in an aluminium industry surrounding area on purpose to evaluate dietary aluminium intake level for rent animals originated from fodder and water consumed by them. There were taken feed and water samples in different periods and from increasing distances from industrial platform, determined the aluminium level by atomic spectroscopy and calculated the rations for cattle and poultry. Conclusions: aluminium dietary intake level by ration depends by forage period for studied species, rations structure and distance from industrial platform and didn’t reach toxic level in any case.

  2. ARE THE EUROPEAN UNION CAP’S SUBSIDIES A POLITICAL RENT? AN ATTEMPT AT METHODOLOGY DEVELOPMENT

    Directory of Open Access Journals (Sweden)

    2014-03-01

    Full Text Available According to the “induced innovation model of agricultural development” there exist mechanisms for this sector’s participation in contributing to economic development, as well as in sharing its benefits. Nonetheless, inefficiencies of the market that distort market signals, constitute a barrier of the latter process. Therefore, the so-called “surplus drainage” from agriculture takes place. The authors claim that it is possible to objectively measure a “surplus drainage” from agriculture as a result of market failure. Assuming that rural areas generate public goods (i.e. a landscape, a biodiversity, rural culture and tradition, unique food quality, food safety, food security speculative land investors have lower willingness to contribute to its creation, than family farms. This is why agrarian policy levies more duties on them (institutional barriers and favours farmers. The mentioned premises imply that the CAP’s subsidies should not be perceived as political rents according to its classical definition. Only a part of subsidies left after subtracting a value of “surplus drainage” and a compensation of public goods has a hallmark of the rent. A valuation of these values is an important scientific challenge.

    The rental of housing units by landlords to participants in Housing First (HF) programs is critical to the success of these programs. Therefore, it is important to understand the experiences of landlords with having these individuals as tenants. The paper presents findings of qualitative interviews with 23 landlords who rented to tenants from a HF program located in a small city and adjoining rural area in eastern Canada and in which approximately 75 % of tenants had been housed for at least six consecutive months at 2 years in the program. Findings showed that landlords are motivated to rent to HF tenants for financial and pro-social reasons. They reported holding a range of positive, neutral, and negative perceptions of these tenants. They identified problems encountered with some HF tenants that included disruptive visitors, conflict with other tenants, constant presence in their apartments, and poor upkeep of units. On the other hand, landlords perceived HF tenants as being mostly good tenants who are similar to their other tenants. Implications for practice in the context of HF programs are discussed.

    Full Text Available Abstract Background When measuring neighbourhood effects on health, it is both incorrect to treat individuals as if they were static and tied to their residential neighbourhood and to consider neighbourhoods rigid places whose geographical scales can be delineated a priori. We propose here to investigate the effects of residential medical density on health-seeking behaviours, taking into account the mono/polycentric structure of individual activity space (i.e., the space within which people move in the course of their daily activities and exploring various neighbourhood units based on administrative delineations and regular grids. Methods We used data collected in the SIRS cohort study, which was carried out over a 5-year period (2005–2010 among a representative population living in 50 census blocks in the Paris metropolitan area. In the 662 women who lived in the same census blocks during the follow-up period and who had reported a recent cervical screening at baseline, we studied the association between residential medical density and individual activity space and the incidence of delayed cervical screening (> 3 years in multilevel logistic regression models after adjustment for potential confounders. Results Among the 662 women studied, there were 94 instances of delayed cervical screening in 2010 (14%. The women who indicated that their activity space was concentrated within their neighbourhood of residence were significantly more at risk for an incident delayed cervical screening. No significant association was found between residential medical density and the incidence of delayed cervical screening. However, we observed a significant interaction between individual activity space and residential medical density. Indeed, women living in neighbourhoods with a low medical density had a significantly higher risk of delayed screening, but only if they reported that their daily activities were centred within their neighbourhood of residence

    In many vertebrate species, certain individuals will seek out opportunities for aggression, even in the absence of threat-provoking cues. Although several brain areas have been implicated in the generation of attack in response to social threat, little is known about the neural mechanisms that promote self-initiated or 'voluntary' aggression-seeking when no threat is present. To explore this directly, we utilized an aggression-seeking task in which male mice self-initiated aggression trials to gain brief and repeated access to a weaker male that they could attack. In males that exhibited rapid task learning, we found that the ventrolateral part of the ventromedial hypothalamus (VMHvl), an area with a known role in attack, was essential for aggression-seeking. Using both single-unit electrophysiology and population optical recording, we found that VMHvl neurons became active during aggression-seeking and that their activity tracked changes in task learning and extinction. Inactivation of the VMHvl reduced aggression-seeking behavior, whereas optogenetic stimulation of the VMHvl accelerated moment-to-moment aggression-seeking and intensified future attack. These data demonstrate that the VMHvl can mediate both acute attack and flexible seeking actions that precede attack.

  11. Activation of D1/5 Dopamine Receptors: A Common Mechanism for Enhancing Extinction of Fear and Reward-Seeking Behaviors.

    Abraham, Antony D; Neve, Kim A; Lattal, K Matthew

    2016-07-01

    Dopamine is critical for many processes that drive learning and memory, including motivation, prediction error, incentive salience, memory consolidation, and response output. Theories of dopamine's function in these processes have, for the most part, been developed from behavioral approaches that examine learning mechanisms in appetitive tasks. A parallel and growing literature indicates that dopamine signaling is involved in consolidation of memories into stable representations in aversive tasks such as fear conditioning. Relatively little is known about how dopamine may modulate memories that form during extinction, when organisms learn that the relation between previously associated events is severed. We investigated whether fear and reward extinction share common mechanisms that could be enhanced with dopamine D1/5 receptor activation. Pharmacological activation of dopamine D1/5 receptors (with SKF 81297) enhanced extinction of both cued and contextual fear. These effects also occurred in the extinction of cocaine-induced conditioned place preference, suggesting that the observed effects on extinction were not specific to a particular type of procedure (aversive or appetitive). A cAMP/PKA biased D1 agonist (SKF 83959) did not affect fear extinction, whereas a broadly efficacious D1 agonist (SKF 83822) promoted fear extinction. Together, these findings show that dopamine D1/5 receptor activation is a target for the enhancement of fear or reward extinction.

    Recently battery leasing has been introduced into the market by automobile manufacturers and power suppliers due to its potential to reduce the purchase cost of electric vehicles (EVs). However, the profit prospect of battery leasing is still uncertain. This paper takes the views of both the operators and consumers and calculates the 'win-win' marginal rent, which not only ensures the profitability of operators, but also allows consumers a lower expenditure than using Internal combustion engine vehicles (ICVs) and EVs with embedded batteries. Battery cost, vehicle weight, gasoline and electricity price, and the discount rate have impacts on the rent. Battery cost plays a dominant role and a battery cost >5 Yen /W h fails to enable the survival of battery leasing to all types of EVs. Battery leasing would be more competitive when focusing on heavier EVs. At least one of the three thresholds is required for the existence of rent pricing range for a 1000 kg EV: gasoline retail price >6 Yen /L, electricity price <0.6 Yen /kW h, or the discount rate <7%. Typically, the feasible battery rent range is 0.34-0.38 Yen /W h/year for a 1000 kg EV under the present battery cost 2 Yen /W h and China current gasoline and electricity prices. - Highlights: > Rent pricing for EV battery leasing must obey win-win rule for BLO and consumers. > Rent is affected by battery cost, vehicle weight, energy price and discount rate. > Battery cost plays dominant role for the BLO survival as described in '5-3-2' Law. > Heavier EVs are more suitable for battery leasing when battery cost is high. > The profitability of BLO is sensitive to the price of gasoline and electricity.

    Full Text Available The textile and clothing industry generates much pollution and consumes a large amount of resources. Improper uses and disposal of clothing products make the problems much more severe. Fast fashion products shorten the valid lifecycle and generate more waste than regular clothing products. Considering the features of fashion products, a system of a rent-based closed-loop supply chain is developed to improve the sustainability of fashion products. The supply chain processes (fashion design and manufacturing, laundry, logistics and disposal, the operations management issues (inventory management, closed-loop logistics, human-clothing matching, booking system and the rental pricing and the sustainability promotion aspects (customization, responsive system, culture and policy aspects are investigated by devising sustainable strategies. The rationalities of the developed system and strategies are reviewed and elucidated in detail. The results may contribute to building sustainable closed-loop fashion supply chains, the related information systems and operational and managerial mechanisms.

    2017-04-01

    Given the many different types of professionals working in public health and their diverse roles, it is likely that their information needs, information-seeking behaviors, and problem-solving abilities differ. Although public health professionals often work in interdisciplinary teams, few studies have explored their information needs and behaviors within the context of teamwork. This study explored the relationship between Canadian public health professionals' perceptions of their problem-solving abilities and their information-seeking behaviors with a specific focus on the use of evidence in practice settings. It also explored their perceptions of collaborative information seeking and the work contexts in which they sought information. Key Canadian contacts at public health organizations helped recruit study participants through their list-servs. An electronic survey was used to gather data about (a) individual information-seeking behaviors, (b) collaborative information-seeking behaviors, (c) use of evidence in practice environments, (d) perceived problem-solving abilities, and (e) demographic characteristics. Fifty-eight public health professionals were recruited, with different roles and representing most Canadian provinces and one territory. A significant relationship was found between perceived problem-solving abilities and collaborative information-seeking behavior (r = -.44, p information seeking. The results suggested that when public health professionals take a shared, active approach to problem solving, maintain personal control, and have confidence, they are more likely collaborate with others in seeking information to complete a work task. Administrators of public health organizations should promote collaboration by implementing effective communication and information-seeking strategies, and by providing information resources and retrieval tools. Public health professionals' perceived problem-solving abilities can influence how they collaborate in

    2013-06-01

    The purpose of this study was the exploration of international travel experiences for the purpose of medical or dental care from the perspective of patients from Alaska and to develop insight and understanding of the essence of the phenomenon of medical tourism. The study is conceptually oriented within a model of health-seeking behavior. Using a qualitative design, 15 Alaska medical tourists were individually interviewed. The data were analyzed using a hermeneutic process of inquiry to uncover the meaning of the experience. Six themes reflecting the experiences of Alaska medical tourists emerged: "my motivation," "I did the research," "the medical care I need," "follow-up care," "the advice I give," and "in the future." Subthemes further categorized data for increased understanding of the phenomenon. The thematic analysis provides insight into the experience and reflects a modern approach to health-seeking behavior through international medical tourism. The results of this study provide increased understanding of the experience of obtaining health care internationally from the patient perspective. Improved understanding of medical tourism provides additional information about a contemporary approach to health-seeking behavior. Results of this study will aid nursing professionals in counseling regarding medical tourism options and providing follow-up health care after medical tourism. Nurses will be able to actively participate in global health policy discussions regarding medical tourism trends. © 2013 Sigma Theta Tau International.

    Srivastava Suresh C.

    2002-01-01

    Full Text Available Bone-seeking therapeutic radiopharmaceuticals are utilized on the basis of the radionuclide?s particulate emissions (primarily low to intermediate beta emission. The requirements therefore are different from those of bone imaging agents that consist mainly of short-lived single photon emitters. Lately, the therapeutic bone seeking radiopharmaceuticals have attained increasing importance due to their potential role in alleviating pain from osseous metastases in cancer patients, for the treatment of joint pain resulting from inflamed synovium (radiosynoviorthesis, or radiosynovectomy, or from various other forms of arthritic disease. There is, however, a paucity of published data on the bio-pharmacokinetics of these agents when used following intravenous administration for bone pain palliation. This paper will briefly review and summarize the presently available chemical and biopharmacokinetic information on the various clinically approved as well as experimental bone-localizing therapeutic radiopharmaceuticals, and make projections on their clinical application for the treatment of primary/metastatic cancer in bone.

  15. The failure of introducing market institution in a rent sector into an economy in transition

    Energy Technology Data Exchange (ETDEWEB)

    Locatelli, C.; Finon, D

    2003-07-01

    Privatisation is at the heart of the structural reforms for economies in transition. In theory, the main aim of privatisation is to change the structures of corporate governance in order to improve the efficiency of the enterprises and to assure their long-term future in a competitive environment. The adoption of formal market institutions would be sufficient to secure the new property rights, in particular because the new holders of the rights to control assets would have a great incentive to encourage the definition of new judicial rules that would guarantee their rights of ownership. In Russia that did not happen. The paper discusses the narrowed vision of institutional change, without consideration of the previous environment of formal and informal institutions, and the need to put together the institutional infrastructure that is needed for the market institutions to function. It offers explanations of the 'unexpected' results of the reforms in a capital-intensive natural resource industry, namely the hydrocarbons industry characterized by the opportunity of rent extraction by the exportation. It demonstrates right holders' interest for the weakness of the 'rule of law'. It demonstrates that the incompatibility of these institutions with the initial informal and formal institutions has led to adaptations that are strongly path-dependent, under the need to preserve a minimum of inter-industrial coherence.

    Full Text Available Effects of castration on performance and profitability of finishing beef cattle in feedlot was evaluated and compared to no-castrated animals. Data came from a rent feedlot of beef cattle, conducted from August to November of 2005. Half of 50 animals, randomly chosen, were castrated by knife 18 days before the beginning of feedlot. Averages of initial body weight for castrated and no-castrated animals were 341kg and 347kg, while for final body weight were 437kg and 463kg, respectively. Were considered as expenses arroba value of thin cattle (R$50.00, and R$2.85 daily expenses per animal paid by cattle owner to “boitel”; and were considered as earnings sale of fat cattle at R$56.14 and R$54.14/arroba, respectively for castrated and no-castrated animals. For profitability analysis, CU$TO BOVINO CORTE software was utilized. Was tested the mean differences between castrated and intact groups by Student t test of average daily weight gains (GMPD and total weight gain (GMPT. Was acceptable the minimum level of confidence of 95%. Statistical analysis was performed in SPSS 17.0 program. Effect of castration negatively influenced animals´ performance, evaluated by weight gain, and, consequently profitability of the system, evaluated by net margin. Earnings from sale of additional arrobas of no-castrated animals were enough to compensate penalization practiced by packinghouses for these animals.

    We present a comparative study of conductive form of polyaniline, i.e, polyemeraldine doped with HCl vapor or with HCSA upon m-cresol vapor. UV-Vis.-nir absorption measurements on polyaniline thin films, vs acid vapors time exposure, have been made. In the same way, Raman spectra have been recorded with different excitation lines from the blue and red ranges to the infrared region. Finally, an assignment of Raman bands observed, is proposed and confirmed by vibrational calculations based on valence-force-field. Nous présentons une étude comparative de la forme conductrice de la polyaniline, c'est-à-dire de la polyéméraldine dopée par des vapeurs d'HCl ou dopée par l'acide camphre sulfonique (HCSA) sous vapeurs de m-crésol. Des mesures d'absorption UV-Vis-proche infrarouge sur des films minces de polyaniline, en fonction du temps d'exposition aux vapeurs acides, ont été réalisées. Parallèlement, les spectres Raman ont été obtenus pour différentes longueurs d'onde d'excitation allant du visible jusqu'au proche infrarouge. Finalement, une attribution des bandes Raman observées est proposée et confirmée par des calculs vibrationnels basés sur des champs de force de valence.

    Full Text Available Background: Vietnam has experienced a strong wave of migrants to urban and industrialized areas. This is a challenge for both local and national governments, which need to address the problems of the poor and socially marginalized, including providing housing for rural-to-urban migrants. Poor housing and the economic burden of house renting are increasingly recognized as determinants of both physical and mental health. Objectives: This paper examined the association between renting accommodation and income satisfaction and living conditions of female workers in light manufacturing industries in Vietnam. Methods: A cross-sectional study was implemented with quantitative survey of 2,818 female workers in 10 light manufacturing factories in 3 industrial zones by a self-administered questionnaire. Results: Over 38% of female workers had to rent accommodation. The average expense for accommodation, water and electricity accounted for 30.1% of renters’ income, which is 7.2% (CI 95%, 5.3–9.3% higher than for non-renters. A higher proportion of renters than non-renters considered their income was unstable and insufficient for living costs. In addition, only 7.2% of renters reported that their living conditions were suitable, notably lower than non-renters (22.4%. Conclusion: The study showed the economic burden of renting accommodation on workers’ income satisfaction and living conditions. The findings have implications for an adequate housing access strategy for workers including the integration of housing development in the planning and development of industrial zones and factories.

    Full Text Available The setting mechanism of the remuneration proper to the factors of production is not different from the merchandise price determination, in this case the type of the market pattern being. When the price of the production factors is determined it must be considered both the type of the market where the goods are sold (as output of the manufacture process and the type of the market where the production factors are provided (engaged. Among the incomes determined by using the production factors mix, the rent represents a very important one. Due to its long term existence, the revenue of rent is one of the economical notion, which has the largest application and the most different signification. For a long time, the rent was attached to the use of the natural resources, especially to those of the earth. Nowadays the application area of this notion has been extended over some other factors of production. In Romania, on the ground of the mining branch development, there were not too many reason of the economic efficiency and the theoretical developments with reference to the costs generated by using the factors of production were ignored. The correct substantiation of the decisions with reference to the application of the national mineral potential can’t ignore the costs generated by the remuneration of the production factor in the mining revenue system.

    Reducing information rents is an important task for government agencies wishing to purchase maximal environmental services with limited budgets. This paper reports on several green auction options for reducing information rents and improving the performance of the “Grain for Green” Payments for environmental services (PES) program implemented in northwestern China. In r experimental auctions and investigations, door-to-door interviews were conducted and bidding envelopes and survey questionnaires were used to determine the offers and the foregone profits of the participants. Three scenarios are analyzed in this paper: a uniform price auction, a discriminatory price auction, and an opportunity-cost system. The results show that compared to the uniform price auction system, the other auction systems can increase the cost-effectiveness of conservation contracting. Competitive bidding can reveal true opportunity costs and can reduce information rents extracted from the government by farmers using private information. The demographics and average bids of these auction types were also analyzed. “Perfect information” in the opportunity-cost offer system has the best performance but is very hard to implement in reality. The results of this research show that the auction is a valuable tool for purchasing conservation contracts in northwestern China, but that in the future, the performance of these auctions should be studied with relaxed model assumptions.

    Value can be created through inter-organizational relationships, but not all participants can get benefit or get equal benefit from network cooperation. This paper addresses the issue of what types of rents,generated through network, are extracted by participating firms. We differentiate participant's rents between common rent and private rent and further divided into three sources: appropriated common rent, internal quasi-rent and net inbound spillover rent. All the three rents are related to the partner's resource base and resource nature.Appropriated common rent is created from the shared resourced of all participants and should be distributed among all members; quasi-rent and net inbound spillover rent come from the firm's non-shared resources which is effected by shared resources and partner's non-shared resources.%网络合作虽然可以产生协同协应,但并非所有参与者都能够从中获取均等收益.本文从网络参与者的角度分析了其从网络合作中的获益,认为参与者的租金主要来源于共有租金和私有租金两个方面,具体细分为可占用的共有租金、内部准租金和溢入租金净值三种类型.这三类租金的实现与参与者所拥有的资源基础和资源属性密切相关,可占用的共有租金是网络参与者通过资源交换、联合、共享而创造的共有租金在不同参与者之间分配的结果;内部准租金和溢入租金净值是参与者的私有资源(或非共享资源)产生的独有的、不与其他参与者分享的私有租金,私有租金的实现也与网络合作密不可分.

    2005-01-01

    Full Text Available The results of a qualitative, naturalistic, study of information seeking behaviour are reported in this paper. The study applied the methods recommended by Lincoln and Guba for maximising credibility, transferability, dependability, and confirmability in data collection and analysis. Sampling combined purposive and snowball methods, and led to a final sample of 45 inter-disciplinary researchers from the University of Sheffield. In-depth semi-structured interviews were used to elicit detailed examples of information seeking. Coding of interview transcripts took place in multiple iterations over time and used Atlas-ti software to support the process. The results of the study are represented in a non-linear Model of Information Seeking Behaviour. The model describes three core processes (Opening, Orientation, and Consolidation and three levels of contextual interaction (Internal Context, External Context, and Cognitive Approach, each composed of several individual activities and attributes. The interactivity and shifts described by the model show information seeking to be non-linear, dynamic, holistic, and flowing. The paper concludes by describing the whole model of behaviours as analogous to an artist's palette, in which activities remain available throughout information seeking. A summary of key implications of the model and directions for further research are included.

    Full Text Available Introduction. The aim of this paper is to deal with the information seeking and use problem in a professional context and understand how activity can influence practices, by taking as examples, the research undertaken by economic analysts. We analyse the relationship between the situational approach, described by Cheuk, the work environment complexity (with social, technological and personal aspects, and the information seeking and use strategies, which relied on Ellis and Wilson's model, with Bates's comments. Method. We interviewed eight economists, using a questionnaire and the SICIA (Situation, Complexity and Information Activity method. The SICAI method is a qualitative approach, which underlines the relationship between situations, professional contexts and strategies. Both methods allow better understanding of how investment analysts find out what they need for their job. We can clarify their information sources and practices of information seeking, which are very particular because of their activities. We complete our analysis by interviewing analysts from financial institutions. Analysis. A qualitative mode of analysis was used to interpret the interviewees' comments, within the research framework adopted. Results. We find similarity in information seeking and use strategies used by these two groups and environmental levels meet in most situations. But some differences can be also found, explained by the activity frameworks and goals. Conclusion. This study demonstrates that the activity and also the professional context (here the financial context can directly influence practices.

  11. Soil erosion and mitigation measures on rented and owned fields in Uruguay: the impact of transgenic soya and foreign investors

    2014-05-01

    Governments, companies and individuals with financial capital to invest, are worldwide buying or renting land in developing or third world countries. Uruguay is a developing country whose economy is mainly based on agriculture. Since 2000 many foreigners started to invest in the Uruguayan agricultural sector and to practice intensive large-scale agriculture. The significant presence of foreigners in the country is proven by the fact that almost 360 000 ha out of the 500 000 ha forming the study area were managed by foreigners in 2012. Nowadays farmers have abandoned the traditional crop rotation plan that included pasture to produce grain for export, and transgenic soya (soya RR) became the main crop planted by both foreigners and locals. Besides the high soil erosion rates related to having soya as main crop, planting soya implies the use of glyphosate, a broad-spectrum systemic herbicide leading to important environmental impacts. It is commonly said that foreigners investing in poor countries are exploiting the local natural resources aiming to get the highest possible profit from them. Is this a valid assumption in Uruguay? The purpose of this study was to compare the land management style of foreign and local farmers and to relate it to the soil erosion occurring in the study area. The land tenure (rented or owned fields) and the type of farmer interviewed ("individual farmer" equivalent to L.L.C. or "anonymous society" equivalent to P.L.C.) were taken into consideration during the analysis. Based on what stated by the farmers interviewed, the soil erosion simulations considered the seven most popular crop rotation plans on rented and owned fields, three ideals crop rotation plans, the application of no mitigation measures, and the construction of terraces and conservation buffers. Depending on the crop rotation plan, soils characterized by slope gradients higher than 2 resulted in soil erosion rates higher than the 7 ton/ha/year allowed by law. The highest

    moderne in zagovarja nujnost absolutne demokracije pri upravljanju, vzpostavljanju in dojemanju skupnega. /// English title: The Permanence of Primitive Accumulation, or: On the Private Property, Commodification and Return of the Rent /// Abstract: In his analysis of current social antagonisms, the author starts from a critique of political economy and focuses on two historically and politically/theoretically important concepts, without which it would not be possible to understand the development of the capitalist system and the way it currently functions: primitive accumulation and modern private property. Newer interpretations of the process of primitive accumulation (Perelman, DeAngelis, Harvey start from the premise that primitive accumulation is not just a historical period belonging to the past, but a necessarily present part of capital in its expansion and search for news ways out of recurring crises. This permanence of primitive accumulation, which Harvey refers to as accumulation-by-disposses sion, in which a key factor is the difference between the generation and existence of capital, helps us to understand the ever present processes of capital expansion and their often violent incorporation of various fields. Although these processes are an always-already-present characteristic of capitalism, by manifesting themselves, they have marked the past decades, when capital has attempted to resolve its own profitability crisis through financialisation and privatisation. At the same time, because the existence of the modern form of private property has appeared as an important condition for capitalist accumulation and as that element which facilitates the effective functioning, development and expansion of capitalist relations of production, at the beginning of the article, this socially constructed phenomenon of modern society, which, through a process of reductionism, makes it almost impossible to consider different forms of ownership such as common forms of property

    The growing amount of information provided via web-based information technologies forces the users of these technologies to stop seeking for information before having acquired all available information. This stopping decision is either made actively following clear guidelines or subconsciously based on the seeker's intuition. This book analyzes the aforementioned duality by developing and testing a multi-theoretical research model dealing with information seeking stopping behavior in online scenarios. Thus, by delivering insights into the mechanisms that influence information seeking activitie

    Effective screening tools are available for many of the top cancer killers in the USA. Searching for health information has previously been found to be associated with adhering to cancer screening guidelines, but Internet information seeking has not been examined separately. The current study examines the relationship between health and cancer Internet information seeking and adherence to cancer screening guidelines for breast, cervical, and colorectal cancer in a large nationally representative dataset. The current study was conducted using data from the Health Information National Trends Survey from 2003 and 2007. The study examined age-stratified models which correlated health and cancer information seeking with getting breast, cervical, and colorectal cancer screening on schedule, while controlling for several key variables. Internet health and cancer information seeking was positively associated with getting Pap screening on schedule, while information seeking from any sources was positively associated with getting colorectal screening on schedule. People who look for health or cancer information are more likely to get screened on schedule. Some groups of people, however, do not exhibit this relationship and, thus, may be more vulnerable to under-screening. These groups may benefit more from targeted interventions that attempt to engage people in their health care more actively.

    The aim of the study was to evaluate the predictors and reasons for help-seeking behavior among women with urinary incontinence (UI) in Germany and Denmark. This international postal survey was conducted in 2014. In each country, 4,000 women of at least 18 years of age were randomly selected. The questionnaires included validated items regarding help-seeking behavior and the ICIQ-UI SF. UI was defined as any involuntary loss of urine. Binary logistic regression analysis was used to assess factors predicting help-seeking behavior. Reasons for seeking or not seeking help were evaluated in terms of the severity of UI and as the most frequently reported. Of 1,063 Danish women with UI, 25.3% had consulted a physician compared with 31.4% of 786 German women with UI (p = 0.004). The severity and duration of UI, and actively seeking information regarding UI, were significant independent predictors of help-seeking behavior. Women with slight/moderate UI did not seek help because they did not consider UI as a problem, whereas of women with severe/very severe UI, German women reported that other illnesses were more important and Danish women reported that they did not have enough resources to consult a physician. Only a small proportion of women with UI had consulted a physician, and the driving forces for help-seeking behavior were severity and duration of UI and actively seeking information regarding UI. Public information campaigns might enhance consultation rates providing that passively receiving and actively seeking information have the same effects on help-seeking behavior. We show for the first time that reasons for not consulting a physician for UI vary depending on the severity of the UI.

    Kahlor, LeeAnn

    2010-06-01

    Recent attention on health-related information seeking has focused primarily on information seeking within specific health and health risk contexts. This study attempts to shift some of that focus to individual-level variables that may impact health risk information seeking across contexts. To locate these variables, the researcher posits an integrated model, the Planned Risk Information Seeking Model (PRISM). The model, which treats risk information seeking as a deliberate (planned) behavior, maps variables found in the Theory of Planned Behavior (TPB; Ajzen, 1991) and the Risk Information Seeking and Processing Model (RISP; Griffin, Dunwoody, & Neuwirth, 1999), and posits linkages among those variables. This effort is further informed by Kahlor's (2007) Augmented RISP, the Theory of Motivated Information Management (Afifi & Weiner, 2004), the Comprehensive Model of Information Seeking (Johnson & Meischke, 1993), the Health Information Acquisition Model (Freimuth, Stein, & Kean, 1989), and the Extended Parallel Processing Model (Witte, 1998). The resulting integrated model accounted for 59% of the variance in health risk information-seeking intent and performed better than the TPB or the RISP alone.

    Case, Donald O.; Andrews, James E.; Johnson, J. David; Allard, Suzanne L.

    2005-01-01

    Question: How have theorists and empirical researchers treated the human tendency to avoid discomforting information? Data Sources: A historical review (1890–2004) of theory literature in communication and information studies, coupled with searches of recent studies on uptake of genetic testing and on coping strategies of cancer patients, was performed. Study Selection: The authors' review of the recent literature included searches of the MEDLINE, PsychInfo, and CINAHL databases between 1992 and summer of 2004 and selective, manual searches of earlier literature. Search strategies included the following subject headings and key words: MeSH headings: Genetic Screening/psychology, Decision Making, Neoplasms/diagnosis/genetics/psychology; CINAHL headings: Genetic Screening, Genetic Counseling, Anxiety, Decision Making, Decision Making/Patient; additional key words: avoidance, worry, monitoring, blunting, cancer. The “Related Articles” function in MEDLINE was used to perform additional “citation pearl” searching. Main Results: The assumption that individuals actively seek information underlies much of psychological theory and communication practice, as well as most models of the information-seeking process. However, much research has also noted that sometimes people avoid information, if paying attention to it will cause mental discomfort or dissonance. Cancer information in general and genetic screening for cancer in particular are discussed as examples to illustrate this pattern. Conclusion: That some patients avoid knowledge of imminent disease makes avoidance behavior an important area for social and psychological research, particularly with regard to genetic testing.

    Based on the model of the bid rent function in a mono-centric city,this paper,by introducing the concept of opportunity cost and extending partial equilibrium analysis to general equilibrium analysis,conducts a theoretical analysis on the possibility that the typical car use taxes including fuel consumption tax,traffic congestion tax,and parking tax can affect the urban space development through their impact on transport cost and the rent bid under certain conditions.Some conclusions drawn from the comparison might be useful when it comes to the practical problems of urban space development.

  15. Host-Seeking Behavior in the Bed Bug, Cimex lectularius

    Directory of Open Access Journals (Sweden)

    2011-03-01

    Full Text Available The reemergence of the bed bug, Cimex lectularius Linnaeus, has recently spawned a frenzy of public, media, and academic attention. In response to the growing rate of infestation, considerable work has been focused on identifying the various host cues utilized by the bed bug in search of a meal. Most of these behavioral studies examine movement within a confined environment, such as a Petri dish. This has prevented a more complete understanding of the insect’s host-seeking process. This work describes a novel method for studying host-seeking behavior, using various movement parameters, in a time-lapse photography system. With the use of human breath as an attractant, we qualitatively and quantitatively assessed how bed bugs navigate their environment between its harborage and the host. Levels of behavioral activity varied dramatically between bed bugs in the presence and absence of host odor. Bed bugs demonstrated not simply activation, but attraction to the chemical components of breath. Localized, stop-start host-seeking behavior or alternating periods of movement and pause were observed among bed bugs placed in the environment void of human breath, while those exposed to human breath demonstrated long range, stop-start host-seeking behavior. A more comprehensive understanding of bed bug host-seeking can lead to the development of traps and monitors that account for unique subtleties in their behavior. The time-lapse photography system uses a large, artificial environment and could also be employed to study other aspects of the insect’s behavioral patterns.

  16. PID Tuning Using Extremum Seeking

    Killingsworth, N; Krstic, M

    2005-11-15

    ]. This method is based on the performance of the closed-loop system during a step response experiment [10], [11]. In this article we present a method for optimizing the step response of a closed-loop system consisting of a PID controller and an unknown plant with a discrete version of extremum seeking (ES). Specifically, ES is used to minimize a cost function similar to that used in [10], [11], which quantifies the performance of the PID controller. ES, a non-model-based method, iteratively modifies the arguments (in this application the PID parameters) of a cost function so that the output of the cost function reaches a local minimum or local maximum. In the next section we apply ES to PID controller tuning. We illustrate this technique through simulations comparing the effectiveness of ES to other PID tuning methods. Next, we address the importance of the choice of cost function and consider the effect of controller saturation. Furthermore, we discuss the choice of ES tuning parameters. Finally, we offer some conclusions.

    Sexual information seeking is an important element within human information behavior. Seeking sexually related information on the Internet takes many forms and channels, including chat rooms discussions, accessing Websites or searching Web search engines for sexual materials. The study of sexual Web queries provides insight into sexually-related information-seeking behavior, of value to Web users and providers alike. We qualitatively analyzed queries from logs of 1,025,910 Alta Vista and AlltheWeb.com Web user queries from 2001. We compared the differences in sexually-related Web searching between Alta Vista and AlltheWeb.com users. Differences were found in session duration, query outcomes, and search term choices. Implications of the findings for sexual information seeking are discussed.

  6. Intention to seek information on cancer genetics

    J.E. Andrews

    2005-01-01

    Full Text Available Objective. The public has a high interest in seeking personal genetic information, which holds implications for health information seeking research and health care policy. Rapid advances in cancer genetics research promise early detection, prevention and treatment, yet consumers may have greater difficulty finding and using the information they may need to make informed decisions regarding their personal health and the future of their families. Design. A statewide telephone survey was conducted of non-institutionalized Kentucky residents 18 years of age or older to investigate factors associated with the intention to seek cancer genetics information, including the need for such information seeking help. Results. The results show that intention to seek cancer genetics information, if testing were readily available, is moderately high (62.5% of those responding; n=835, and that status as a racial minority, the perception that cancer runs in one's family, and frequent worrying about cancer risk are statistically significant predictors of intent to seek genetics information. Conclusion. . We argue that an already complex health information environment will be even more difficult for individuals to navigate as genetic research becomes more ubiquitous in health care. An increase in demand for genetics information in various forms, as suggested by these results and those of other studies, implies that enduring intervention strategies are needed to help individuals acquire necessary health information literacy skills, with special attention given to racial minorities.

    2016-01-01

    Purpose The Examining Neighbourhood Activities in Built Living Environments in London (ENABLE London) project is a natural experiment which aims to establish whether physical activity and other health behaviours show sustained changes among individuals and families relocating to East Village (formerly the London 2012 Olympics Athletes' Village), when compared with a control population living outside East Village throughout. Participants Between January 2013 and December 2015, 1497 individuals from 1006 households were recruited and assessed (at baseline) (including 392 households seeking social housing, 421 seeking intermediate and 193 seeking market rent homes). The 2-year follow-up rate is 62% of households to date, of which 57% have moved to East Village. Findings to date Assessments of physical activity (measured objectively using accelerometers) combined with Global Positioning System technology and Geographic Information System mapping of the local area are being used to characterise physical activity patterns and location among study participants and assess the attributes of the environments to which they are exposed. Assessments of body composition, based on weight, height and bioelectrical impedance, have been made and detailed participant questionnaires provide information on socioeconomic position, general health/health status, well-being, anxiety, depression, attitudes to leisure time activities and other personal, social and environmental influences on physical activity, including the use of recreational space and facilities in their residential neighbourhood. Future plans The main analyses will examine the changes in physical activity, health and well-being observed in the East Village group compared with controls and the influence of specific elements of the built environment on observed changes. The ENABLE London project exploits a unique opportunity to evaluate a ‘natural experiment’, provided by the building and rapid occupation of East

  12. Mechanisms of host seeking by parasitic nematodes.

    Science.gov (United States)

    Gang, Spencer S; Hallem, Elissa A

    2016-07-01

    The phylum Nematoda comprises a diverse group of roundworms that includes parasites of vertebrates, invertebrates, and plants. Human-parasitic nematodes infect more than one billion people worldwide and cause some of the most common neglected tropical diseases, particularly in low-resource countries [1]. Parasitic nematodes of livestock and crops result in billions of dollars in losses each year [1]. Many nematode infections are treatable with low-cost anthelmintic drugs, but repeated infections are common in endemic areas and drug resistance is a growing concern with increasing therapeutic and agricultural administration [1]. Many parasitic nematodes have an environmental infective larval stage that engages in host seeking, a process whereby the infective larvae use sensory cues to search for hosts. Host seeking is a complex behavior that involves multiple sensory modalities, including olfaction, gustation, thermosensation, and humidity sensation. As the initial step of the parasite-host interaction, host seeking could be a powerful target for preventative intervention. However, host-seeking behavior remains poorly understood. Here we review what is currently known about the host-seeking behaviors of different parasitic nematodes, including insect-parasitic nematodes, mammalian-parasitic nematodes, and plant-parasitic nematodes. We also discuss the neural bases of these behaviors.

    In medical education, students are increasingly regarded as active seekers of feedback rather than passive recipients. Previous research showed that in the intentions of students to seek feedback, a learning and performance goal can be distinguished. In this study, we investigated the intentions (defined as level and orientation of motivation) of different performing students (low, average, and high performing students) to seek feedback in the clinical workplace using Self-Determination Theory. We conducted a quantitative study with students in their clinical clerkships and grouped them based on their performance. The level of motivation was measured by the number of Mini-CEXs each student collected. The orientation of motivation was measured by conducting the Academic Self-Regulation Questionnaire. We found that high performing students were more motivated and demonstrated higher self-determination compared to low performing students.

Aims: To ascertain the treatment seeking behavior of north Indian women having urinary incontinence (UI. Setting: Two residential colonies of Chandigarh. DESIGN: Cross-sectional face-to-face interview based study. Materials and Methods: This study was conducted by a trained nurse during April 2005-July 2005 among women aged 18 years and above. Women with UI were identified in a screening survey. They were interviewed individually regarding their treatment seeking behavior and socio-demographic data. Statistical Analysis Used: Percentage, mean, standard deviation, chi-square test. Results: Of the 220 enlisted incontinent women 20% (44 women consulted some health agency. Only 8.6% (19 women had heard about pelvic floor muscle exercises. Seventy-two percent (158 cases had UI for more than one year. The most common reason quoted for not seeking treatment was, ′UI was considered as ′normal′, ′did not take it seriously′ and ′shyness.′ Many (153;70% women reported that UI affected their daily routine as well as social activities like shopping and visiting friends. Conclusion: Urinary incontinence seriously affected the quality of life of women. Still, consultation rate for UI was low in the north Indian women.

    This study examined the relationship between parental and adolescent eHealth literacy and its impact on online health information seeking. Data were obtained from 1,869 junior high school students and 1,365 parents in Taiwan in 2013. Multivariate analysis results showed that higher levels of parental Internet skill and eHealth literacy were associated with an increase in parental online health information seeking. Parental eHealth literacy, parental active use Internet mediation, adolescent Internet literacy, and health information literacy were all related to adolescent eHealth literacy. Similarly, adolescent Internet/health information literacy, eHealth literacy, and parental active use Internet mediation, and parental online health information seeking were associated with an increase in adolescent online health information seeking. The incorporation of eHealth literacy courses into parenting programs and school education curricula is crucial to promote the eHealth literacy of parents and adolescents.

    The EU Water Framework Directive (WFD) requires an integrated approach to river basin management in order to meet environmental and ecological objectives. This paper presents concepts and full-scale application of an integrated modelling framework. The Ringkoebing Fjord basin is characterized by intensive agricultural production and leakage of nitrate constitute a major pollution problem with respect groundwater aquifers (drinking water), fresh surface water systems (water quality of lakes) and coastal receiving waters (eutrophication). The case study presented illustrates an advanced modelling approach applied in river basin management. Point sources (e.g. sewage treatment plant discharges) and distributed diffuse sources (nitrate leakage) are included to provide a modelling tool capable of simulating pollution transport from source to recipient to analyse the effects of specific, localized basin water management plans. The paper also includes a land rent modelling approach which can be used to choose the most cost-effective measures and the location of these measures. As a forerunner to the use of basin-scale models in WFD basin water management plans this project demonstrates the potential and limitations of comprehensive, integrated modelling tools.

    2012-01-01

    The gap in cancer information seeking between high-socioeconomic-status (high-SES) cancer patients and low-SES cancer patients deserves serious attention, considering the importance of information and knowledge in cancer control. We thus explored the association of SES, as measured by education, with cancer patients' overall cancer information seeking, and with seeking from each source (i.e., the Internet, mass media, medical sources, and nonmedical interpersonal sources) and across two topic categories (i.e., treatment, quality of life). We then asked whether the effect of education on treatment information seeking is reduced among those who are particularly motivated to control treatment choices. We conducted a survey with breast, prostate, and colon cancer patients diagnosed in 2005 (n = 2,013), who were randomly drawn from the Pennsylvania Cancer Registry in the fall of 2006. We found that education was more strongly associated with Internet use than with the use of other sources regardless of topics. Also, when information was sought from mass media, education had a greater association with treatment information seeking than with quality-of-life information seeking. Preference for active participation in treatment decision making, however, did not moderate the effect of education on treatment information seeking. The implications of these findings for public health research and cancer patient education were discussed.

    Although the research in health seeking behavior has been evolving, its concept remains ambiguous. Concept clarification, as a central basis of developing knowledge, plays an undeniable role in the formation of nursing sciences. As the initial step toward the development of theories and theoretical models, concept analysis is broadly used through which the goals can be used and tested. The aim of this study was to report an analysis of the concept of "health seeking behavior". Employing a rigorous evolutionary concept analysis approach, the concept of health seeking behavior was examined for its implications, use, and significance in the discipline of nursing between 2000 and 2012. After applying inclusion and exclusion criteria, a total of 40 articles and 3 books were selected for the final analysis. The definition of attributes, antecedents, and consequences of health seeking behavior was performed through concept analysis. Core attributes (interactional, processing, intellectual, active, decision making based and measurable) were studied. The antecedents of concept were categorized as social, cultural, economic, disease pattern and issues related to health services. Health-seeking behavior resulted in health promotion and disease risk reduction. In addition, it led to predicting the future probable burden of the diseases, facilitation of the health status, early diagnosis, complete and effective treatment, and complication control. Health-seeking behavior, as a multi-dimensional concept, relies on time and context. An awareness of health-seeking behavior attributes antecedents and consequences results in promoting the status, importance and application of this concept in the nursing profession.

    Full Text Available Introduction: Improvement in health technologies and socio economic conditions increase life expectancy of people leading to higher proportion of elderly in total population of every country worldwide. Developing countries have less comprehensive policy and elderly health agenda, and Myanmar is not an exception. The World Health Organization highlighted that aging process and problems related to elderly should be better understood so that effective elderly health prevention can be planned and implemented. However, there are very limited studies in Myanmar for aging health care. Objective: 1 To identify the Health status of aging population in selected townships of upper and lower Myanmar. 2 To identify the health seeking behavior of elderly. 3 To find out the association between the health seeking behavior of elderly and socio-demographic characteristics. Method: This is a cross sectional survey to study health status and health seeking behavior of the elderly people in Myanmar. Study areas are Taungu from Lower Myanmar and Ye Oo from Upper Myanmar both of which are not under cover of elderly project and have no adequate data for elderly health care. Sample size calculation was done by Epi Info StatCalc. Total 729 elderly were under study. According to elderly population in Taungu and Ye Oo, 1/3 of the sample was taken from Taungu and 2/3 taken from Ye Oo. Result: Male, Female ratio of study population is 1:1.44. Around half of elderly population has primary or lower level education, only one third are working but with low income. One third of male and female elderly perceived that they are in good health. Regarding illnesses present at the time of interview, three percent of male and thirteen percent of female did not get treatment. Significant difference between the health seeking behavior of upper and lower Myanmar was seen with chi square alue 1155, P= <00000001.

    The survey of interview, resource acquisition, photographic operation, and questionnaire were carried out in the “n” Community in the “y” District in Hakusan City in Ishikawa Prefecture to investigate the actual condition of paddy field levee maintenance in the area where land-renting market was proceeding, large-scale farming was dominant, and the problems of geographically scattered farm-land existed. In the study zone, 1) an agricultural production legal person rent-cultivated some of the paddy fields and maintained the levees, 2) another agricultural production legal person rent-cultivated some of the soy bean fields for crop changeover and land owners maintained the levees. The results indicated that sufficient maintenance was executed on the levees of the paddy fields cultivated by the agricultural production legal person, the soy bean fields for crop changeover, and the paddy fields cultivated by the land owners. Each reason is considered to be the managerial strategy, the economic incentive, the mutual monitoring and cross-regulatory mechanism, etc.

    Objective This study aims to examine perceptions of the helpfulness of treatments/interventions for depression held by elderly care recipients, to examine whether these beliefs are related to help-seeking and whether the experience of depression affects beliefs about treatment seeking, and to identify the characteristics of help-seekers. Method One hundred eighteen aged care recipients were surveyed on their beliefs about the helpfulness of a variety of treatments/interventions for depression, on their actual help-seeking behaviors, and on their experience of depression (current and past). Results From the sample, 32.4% of the participants screened positive for depression on the Geriatric Depression Scale, and of these, 24.2% reported receiving treatment. Respondents believed the most helpful treatments for depression were increasing physical activity, counseling, and antidepressant medication. Help-seeking from both professional and informal sources appeared to be related to belief in the helpfulness of counseling and antidepressants; in addition, help-seeking from informal sources was also related to belief in the helpfulness of sleeping tablets and reading self-help books. In univariate analyses, lower levels of cognitive impairment and being in the two lower age tertiles predicted a greater likelihood of help-seeking from professional sources, and female sex and being in the lower two age tertiles predicted greater likelihood of help-seeking from informal sources. In multivariate analyses, only lower levels of cognitive impairment remained a significant predictor of help-seeking from professional sources, whereas both lower age and female sex continued to predict a greater likelihood of help-seeking from informal sources. Conclusion Beliefs in the helpfulness of certain treatments were related to the use of both professional and informal sources of help, indicating the possibility that campaigns or educational programs aimed at changing beliefs about treatments

    Stochastic Averaging and Stochastic Extremum Seeking develops methods of mathematical analysis inspired by the interest in reverse engineering  and analysis of bacterial  convergence by chemotaxis and to apply similar stochastic optimization techniques in other environments. The first half of the text presents significant advances in stochastic averaging theory, necessitated by the fact that existing theorems are restricted to systems with linear growth, globally exponentially stable average models, vanishing stochastic perturbations, and prevent analysis over infinite time horizon. The second half of the text introduces stochastic extremum seeking algorithms for model-free optimization of systems in real time using stochastic perturbations for estimation of their gradients. Both gradient- and Newton-based algorithms are presented, offering the user the choice between the simplicity of implementation (gradient) and the ability to achieve a known, arbitrary convergence rate (Newton).

    Full Text Available Makes an attempt to examine the validity of the construct regarding gendered information behavior. A survey was made for the purpose on a sample of eighty people covering both male and female in equal proportion from four distinct groups, namely Teacher, Student, Skilled Labour and Unskilled Labour from both urban and rural areas. Data were collected from the selected audience, using a combination of both questionnaire and interview, on a set of fixed queries. Results have revealed that the information needs as well as the information seeking behaviour, in general, among the male and female do not show any uniform and consistent pattern. The findings also have revealed that there are variations of needs and behavior for seeking information among an individual man and woman, an individual man and man, as well as an individual woman and woman. But the differences in this regard have been found as quantitative and not qualitative. The findings do not show any evidence of gendered information need as well as information seeking behavior exclusive to the male or female.

    Purpose The Chinese population is rapidly ageing before they are rich. The purpose of this paper is to describe healthcare seeking behaviour and the critical factors associated with healthcare seeking behaviour. Design/methodology/approach Using a purposive sampling method, the authors recruited 44 adults aged 60 years or older from three provinces, representing the developed (Shanghai), undeveloped (Ningxia) regions and the regions in between (Hubei). From July to September 2008, using a semi-structured guide, the authors interviewed participants in focus group discussions. Findings The healthcare needs for chronic and catastrophic diseases were high; however, the healthcare demands were low and healthcare utilizations were even lower owing to the limited accessibility to healthcare services, particularly, in underdeveloped rural areas. "Too expensive to see a doctor" was a prime complaint, explaining substantial discrepancies between healthcare needs, demands and use. Care seeking behaviour varied depending on insurance availability, perceived performance, particularly hospital services, and prescription medications. Participants consistently rated increasing healthcare accessibility as a high priority, including offering financial aid, and improving service convenience. Improving social security fairness was the first on the elderly's wish list. Originality/value Healthcare demand and use were lower than needs, and were influenced by multiple factors, primarily, service affordability and efficiency, perceived performance and hospital service quality.

  13. Evaluating information-seeking approaches to metacognition.

    Science.gov (United States)

    Crystal, Jonathon D; Foote, Allison L

    Metacognition has been divided into information monitoring and control processes. Monitoring involves knowing that you know or do not know some information without taking corrective action. Control involves taking corrective action based on the knowledge that you know or do not know some information. In comparative metacognition, considerable attention has been paid toward critically assessing putative evidence for information monitoring in non-human animals. However, less attention has been paid toward critically evaluating evidence for control processes in animals. We briefly review a critique of information-monitoring in animals. Next, we apply these concepts to a number of studies that focus on information seeking in animals. The main type of evidence for control processes in animals come from tube tipping experiments. Before having the opportunity to search for the bait in these experiments, the subject sometimes observes opaque tubes being baited but is sometimes prevented from seeing the baiting. The observations that the subjects look more if baiting was not seen and are more accurate if baiting was seen have been taken as evidence for metacognition in information-seeking experiments. We propose simple alternative hypotheses that are sufficient to explain putative evidence for information seeking in animals without positing metacognition. The alternative explanation focuses on two relatively simple principles: First, an animal has a default "look before you go" response which supersedes random searches in space. Second, spatially guided behavior follows a default rule of "go where something good is." These principles can explain the results of tube tipping experiments without proposing metacognition.

  14. Flow and rent-based opportunity costs of water ecosystem service provision in a complex farming system

    Directory of Open Access Journals (Sweden)

    Olivia R. Rendon

    2016-12-01

    Full Text Available Unsustainable land uses present many challenges for securing ecosystem service provision. It is also difficult to estimate the cost of a transition to more sustainable land-management practices for individual landholders. The main cost to landholders is the opportunity costs, the income foregone when changing land use for continued or enhanced ecosystem service provision. Thus accurate estimation of opportunity costs and understanding their distribution are crucial starting points for determining the economic viability and design of any payment for ecosystem services (PES scheme. We compare two opportunity cost approaches and examine the distribution of these costs for improving drinking water quality in a complex farming system in a Honduran forest catchment. Data for both approaches was collected through a survey applied to upstream catchment landholders. Our results indicate that the direct flow approach and the proxy rent approach provide comparable and consistent opportunity cost estimates. The mean net flow return ha-1 was US$1410, but this estimate was skewed, mainly by exceptionally high coffee returns and negative returns of land uses making a loss. This estimate would imply spending over US$2 million per annum for water conservation, but a revised estimate comes to US$257,057 per annum. Opportunity costs were found to vary according to differences in land use and landholder characteristics. High value cash crops upholding the local economy, such as coffee, entail much higher opportunity costs than for example cattle grazing. These results suggest that discriminate PES payments, that vary according to opportunity costs and thus discriminate between land uses and landholders, are essential. Water quality at our case study site could be managed sustainably by a scheme focusing on high-impact land uses with lower opportunity costs and closer to water sources.

    travail est d’étudier la faisabilité de la combustion partielle ou totale des charges liquides dans les conditions du CLC au contact d’un matériau porteur d’oxygène. Un petit réacteur en lit fluidisé opérant en batch a été développé pour permettre alternativement le contact du matériau porteur d’oxygène avec une charge liquide ou de l’air. Le réacteur de 20 mm de diamètre est rempli de 45 g de particules de NiAl0.44O1.67. Environ 1-2 g de charge liquide est injecté par pulse dans le lit à des températures allant jusqu’à 950˚C. Différentes charges liquides ont été étudiées, du dodécane au fioul lourd n˚2. Les résultats montrent que pendant la période de réduction du matériau porteur d’oxygène, il est possible de convertir tous les hydrocarbures injectés. À l’issue de cette phase, il ne subsiste pas de dépôt de coke à la surface des particules. En fonction de la quantité d’oxygène disponible dans le lit, on effectue une combustion totale ou partielle des hydrocarbures injectés. Des résultats similaires sont obtenus pour les différents hydrocarbures testés, malgré leurs propriétés a priori très différentes.

While the rent design is a critical issue for sustainable development of public rental housing. BOT could be applied to solve the contradictoriness between relative shortage of financial funds and poor ability of the Public in realizing government’s objectives with the comprehensive advantages of the Private’s capital and capability. Based on some basic principles such as indemnificatory,fairness and sustainable development,this paper conducts an in-depth study and designs a mechanism of pricing the rent of public rental housing. A‘double-rent’ system consists of nominal and real rent is proposed in which the rent paid by the lessee and the subsidy from the government are separated. The paper provides a theoretical basis to improve China's housing security system and an important practical reference for pricing the rent of public rental housing.

We examined and compared the health care seeking behavior for perceived morbidity between urban and rural households in Southwest Ethiopia. Analytic cross-sectional study was conducted among urban and rural households living in Esera district of Southwest Ethiopia. A random sample of 388 head of households (126 urban and 262 rural) were selected. A pretested and structured questionnaire was used for data collection with face-to-face interview. In addition to descriptive methods, binary logistic regression was used to identify factors associated with health seeking behavior at p value of less than 0.05. Of the sample household heads, 377 (97.2%) (119 urban and 258 rural) were successfully interviewed. Among these, 58.4% (95% CI, 53.3-63.3%) of the households sought care from modern health care that was lower among rural (48.1%) than urban (80.7%) households. The prevalence of self-treatment was 35.3% in urban and 46.1% in rural households. Among the factors considered for modern health care utilization, higher monthly income (AOR, 5.6; 95% CI, 2.04-15.4), perceived severity of disease (AOR, 2.5; 95% CI, 1.1-5.8), acute duration of disease (AOR, 8.9; 95% CI, 2.4-33.3) and short distance from health facilities (AOR, 3; 95% CI, 1.2-8.4) among rural and being married (AOR, 11.3; 95% CI, 1.2-110.2) and perceived severity of disease (AOR, 6.6; 95% CI, 1.1-10.9) among urban households showed statistically significant association. The general health seeking behavior of households on perceived morbidity was satisfactory but lower in rural compared to urban households. Self-medication was also widely practiced in the study area. The findings signal the need to work more on accessibility and promotion of healthcare seeking behavior especially among rural households.

  1. Conceptual measurement framework for help-seeking for mental health problems

    Full Text Available Debra Rickwood, Kerry ThomasFaculty of Health, University of Canberra, ACT, AustraliaBackground: Despite a high level of research, policy, and practice interest in help-seeking for mental health problems and mental disorders, there is currently no agreed and commonly used definition or conceptual measurement framework for help-seeking.Methods: A systematic review of research activity in the field was undertaken to investigate how help-seeking has been conceptualized and measured. Common elements were used to develop a proposed conceptual measurement framework.Results: The database search revealed a very high level of research activity and confirmed that there is no commonly applied definition of help-seeking and no psychometrically sound measures that are routinely used. The most common element in the help-seeking research was a focus on formal help-seeking sources, rather than informal sources, although studies did not assess a consistent set of professional sources; rather, each study addressed an idiosyncratic range of sources of professional health and community care. Similarly, the studies considered help-seeking for a range of mental health problems and no consistent terminology was applied. The most common mental health problem investigated was depression, followed by use of generic terms, such as mental health problem, psychological distress, or emotional problem. Major gaps in the consistent measurement of help-seeking were identified.Conclusion: It is evident that an agreed definition that supports the comparable measurement of help-seeking is lacking. Therefore, a conceptual measurement framework is proposed to fill this gap. The framework maintains that the essential elements for measurement are: the part of the help-seeking process to be investigated and respective time frame, the source and type of assistance, and the type of mental health concern. It is argued that adopting this framework will facilitate progress in the field by

    When developing an effective early preventive strategy for employees and students with CANS (Complaints of Arm, Neck or Shoulder, not caused by acute trauma or systemic disease), insight in help seeking behaviour and knowledge of factors associated with help seeking behaviour within the target population, is a prerequisite. The aim of this study was to examine whether perceived hindrance is associated with help seeking behaviour, specifically in employees and students identified with CANS. Additionally, the associations of factors related to functioning and participation, work-environment and demographics with help seeking behaviour were explored in these groups. A cross-sectional survey was conducted among employees and students of two universities in the South of the Netherlands. The questionnaire included questions to assess (1) demographics, work/study and activity related factors (2) experience of CANS (3) perceived hindrance (4) help seeking behaviour. A subpopulation of the survey, consisting of those employees and students with self-reported CANS, received additional questionnaires to examine the impact of (1) participant characteristics (2) complaint and health related variables (3) functioning and participation (4) work-environment and social support, on help seeking behaviour. 37.3% of the employees and 41.4% of the students reported CANS. Of these, respectively 43.3% and 45.5%, did not seek help and had no intention to seek help either. Employees and students who had not sought help reported less hindrance, less perceived disabilities and shorter duration of complaints, compared those who did seek help. Employees and students within this group who had also no intention to seek help, perceived fewer disabilities and reported shorter duration of complaints. The absence of help seeking behaviour in respondents with CANS is a bottleneck for implementation of preventive strategies. In employees and students with CANS, help seeking behaviour is primarily

    This study explores determinants of information-seeking about crime and crime prevention on the Internet, including how it was influenced by personal conversations with others. An analysis of a web survey of mothers (N = 1,040) of 3-12 years old children in Japan indicated that many mothers briefly saw basic information about crime on the Internet, while only a few mothers sought further details. Structural equation modeling indicated the following results. Overall, an increased frequency of conversations about children's safety with family and friends made mothers realize their own responsibility for crime prevention. It also encouraged mothers to seek more information about crime prevention by increasing their willingness to cooperate with neighbors. However, when individuals' realization of responsibility for crime prevention strengthened their attitudes toward the responsibility of the police and government for crime problems, then these attitudes decreased mothers' information-seeking. Finally, while a heightened frequency of conversations about news contents directly increased information-seeking about crime, such conversations could indirectly weaken mothers' information-seeking when mothers emphasized the responsibility of the police and government.

  5. Evaluating information-seeking approaches to metacognition

    2015-01-01

    Metacognition has been divided into information monitoring and control processes. Monitoring involves knowing that you know or do not know some information without taking corrective action. Control involves taking corrective action based on the knowledge that you know or do not know some information. In comparative metacognition, considerable attention has been paid toward critically assessing putative evidence for information monitoring in non-human animals. However, less attention has been paid toward critically evaluating evidence for control processes in animals. We briefly review a critique of information-monitoring in animals. Next, we apply these concepts to a number of studies that focus on information seeking in animals. The main type of evidence for control processes in animals come from tube tipping experiments. Before having the opportunity to search for the bait in these experiments, the subject sometimes observes opaque tubes being baited but is sometimes prevented from seeing the baiting. The observations that the subjects look more if baiting was not seen and are more accurate if baiting was seen have been taken as evidence for metacognition in information-seeking experiments. We propose simple alternative hypotheses that are sufficient to explain putative evidence for information seeking in animals without positing metacognition. The alternative explanation focuses on two relatively simple principles: First, an animal has a default "look before you go" response which supersedes random searches in space. Second, spatially guided behavior follows a default rule of "go where something good is." These principles can explain the results of tube tipping experiments without proposing metacognition.

  6. Beyond the caveman: rethinking masculinity in relation to men's help-seeking.

    2012-03-01

    Statistically, men make less use of health-care services than women. This has been interpreted as the result of the 'hegemonic' masculine code in which 'real' men are understood to be physically fit, uninterested in their health and self-reliant. However, less attention has been paid to understanding how hegemonic masculinity intersects with the wider western socio-cultural contexts of men's help-seeking, particularly the valorization of health as a form of social achievement. This article presents the results of interviews with 14 higher socio-economic status (SES) men to uncover their 'interpretive repertoires' in relation to health and illness, help-seeking and masculinity. Although many interviewees drew on the stereotype of the 'Neanderthal Man' who avoids the doctors to explain help-seeking by men 'in general', they constructed their own experiences of help-seeking in terms of being responsible, problem-solving and in control. It is argued that the framing of help-seeking in terms of 'taking action' chimes with an increasingly pro-active 'expert patient' approach within western health-care. This conceptual reconstruction of the dominant masculine code in relation to help-seeking, from 'Neanderthal Man' to 'Action Man', may lead to greater gender equality in terms of accessing health-care. However, it has the potential to exacerbate social inequalities between men from different SES groups.

    A growing body of evidence indicates that the transport of GluA1 subunit-containing calcium-permeable AMPA receptors (CP-AMPARs) to synapses in subregions of the nucleus accumbens promotes cocaine seeking. Consistent with these findings, the present results show that administration of the CP-AMPAR antagonist, Naspm, into the caudal lateral core or caudal medial shell of the nucleus accumbens attenuated cocaine priming-induced reinstatement of drug seeking. Moreover, viral-mediated overexpression of 'pore dead' GluA1 subunits (via herpes simplex virus (HSV) GluA1-Q582E) in the lateral core or medial shell attenuated the reinstatement of cocaine seeking. The overexpression of wild-type GluA1 subunits (via HSV GluA1-WT) in the medial shell, but not the lateral core, enhanced the reinstatement of cocaine seeking. These results indicate that activation of GluA1-containing AMPARs in subregions of the nucleus accumbens reinstates cocaine seeking. SAP97 and 4.1N are proteins involved in GluA1 trafficking to and stabilization in synapses; SAP97-GluA1 interactions also influence dendritic growth. We next examined potential roles of SAP97 and 4.1N in cocaine seeking. Viral-mediated expression of a microRNA that reduces SAP97 protein expression (HSV miSAP97) in the medial accumbens shell attenuated cocaine seeking. In contrast, a virus that overexpressed a dominant-negative form of a 4.1N C-terminal domain (HSV 4.1N-CTD), which prevents endogenous 4.1N binding to GluA1 subunits, had no effect on cocaine seeking. These results indicate that the GluA1 subunit accessory protein SAP97 may represent a novel target for pharmacotherapeutic intervention in the treatment of cocaine craving.

    Information behavior includes activities of active information seeking, passive acquisition of information, and information use. Guided by the Elaboration Likelihood Model, this study explored elderly Singaporean women's health information behavior to understand how they sought, evaluated, and used health information in everyday lives. Twenty-two in-depth interviews were conducted with elderly Chinese women aged 61 to 79. Qualitative analysis of the interview data yielded three meta-themes: information-seeking patterns, trustworthiness of health information, and peripheral route of decision making. Results revealed that elderly women took both systematic and heuristic approaches to processing information but relied on interpersonal networks to negotiate health choices.

    Promoting healthy gestational weight gain (GWG) is important for preventing obstetric and perinatal morbidity, along with obesity in both mother and child. Provision of GWG guidelines by health professionals predicts women meeting GWG guidelines. Research concerning women's GWG information sources is limited. This study assessed pregnant women's sources of GWG information and how, where and which women seek GWG information. Consecutive women (n = 1032) received a mailed questionnaire after their first antenatal visit to a public maternity hospital in Melbourne, Australia. Recalled provision of GWG guidelines by doctors and midwives, recalled provided GWG goals, and the obtaining of GWG information and information sources were assessed. Participants (n = 368; 35.7% response) averaged 32.5 years of age and 20.8 weeks gestation, with 33.7% speaking a language other than English. One in ten women recalled receiving GWG guidelines from doctors or midwives, of which half were consistent with Institute of Medicine guidelines. More than half the women (55.4%) had actively sought GWG information. Nulliparous (OR 7.07, 95% CI = 3.91-12.81) and obese (OR 1.96, 95% CI = 1.05-3.65) women were more likely to seek information. Underweight (OR 0.29, 95% CI = 0.09-0.97) women and those working part time (OR 0.52, 95% CI = 0.28-0.97) were less likely to seek information. Most frequently reported GWG sources included the internet (82.7%), books (55.4%) and friends (51.5%). The single most important sources were identified as the internet (32.8%), general practitioners (16.9%) and books (14.9%). More than half of women were seeking GWG guidance and were more likely to consult non-clinician sources. The small numbers given GWG targets, and the dominance of non-clinical information sources, reinforces that an important opportunity to provide evidence based advice and guidance in the antenatal care setting is currently being missed.

    Full Text Available Abstract Background Obese and overweight people have a higher risk of both chronic physical illness and mental illness. Obesity is reported to be positively associated with psychiatric disorders, especially in people who seek obesity treatment. At the same time, obesity treatment may be influenced by psychological factors or personality characteristics. This study aimed to understand the prevalence of mental disorders among ethnic Chinese who sought obesity treatment. Methods Subjects were retrospectively recruited from an obesity treatment center in Taiwan. The obesity treatments included bariatric surgery and non-surgery treatment. All subjects underwent a standardized clinical evaluation with two questionnaires and a psychiatric referral when needed. The psychiatric diagnosis was made thorough psychiatric clinic interviews using the SCID. A total of 841 patients were recruited. We compared the difference in psychiatric disorder prevalence between patients with surgical and non-surgical treatment. Results Of the 841 patients, 42% had at least one psychiatric disorder. Mood disorders, anxiety disorders and eating disorders were the most prevalent categories of psychiatric disorders. Females had more mood disorders and eating disorders than males. The surgical group had more binge-eating disorder, adjustment disorder, and sleep disorders than the non-surgical group. Conclusion A high prevalence of psychiatric disorders was found among ethnic Chinese seeking obesity treatment. This is consistent with study results in the US and Europe.

    An adaptive interface autonomously adjusts its display and available actions to current goals and abilities of the user by assessing user status, system task, and the context. Knowledge content adaptability is needed for knowledge acquisition and refinement tasks. In the case of knowledge content adaptability, the requirements of interface design focus on the elicitation of information from the user and the refinement of information based on patterns of interaction. In such cases, the emphasis on adaptability is on facilitating information search and knowledge discovery. In this article, we present research on adaptive interfaces that facilitates personalized information seeking from a large data warehouse. The resulting proof-of-concept system, called source recommendation system (SRS), assists users in locating and navigating data sources in the repository. Based on the initial user query and an analysis of the content of the search results, the SRS system generates a profile of the user tailored to the individual's context during information seeking. The user profiles are refined successively and are used in progressively guiding the user to the appropriate set of sources within the knowledge base. The SRS system is implemented as an Internet browser plug-in to provide a seamless and unobtrusive, personalized experience to the users during the information search process. The rationale behind our approach, system design, empirical evaluation, and implications for research on adaptive interfaces are described in this paper.

    Full Text Available Diagnosis of mild cognitive impairment relies on the presence of memory complaints. However, memory complaints are very frequent in healthy people. The objective of this study was to determine the severity and type of memory difficulties presented by elderly patients who seek for clinical help, as compared to the memory difficulties reported by subjects in the community. Assessment of subjective memory complaints was done with the subjective memory complaints scale (SMC. The mini-mental state examination was used for general cognitive evaluation and the geriatric depression scale for the assessment of depressive symptoms. Eight-hundred and seventy-one nondemented subjects older than 50 years were included. Participants in the clinical setting had a higher total SMC score (10.3±4.2 than those in the community (5.1±3.0. Item 3 of the SMC, Do you ever forget names of family members or friends? contributed significantly more to the variance of the total SMC score in the clinical sample (18% as compared to the community sample (11%. Forgetting names of family members or friends plays an important role in subjective memory complaints in the clinical setting. This symptom is possibly perceived as particularly worrisome and likely drives people to seek for clinical help.

    To analyze the process of seeking tuberculosis care and this process's impact on treatment adherence in the Mexican state of Chiapas, given that the two primary factors in successful tuberculosis (TB) control programs are early diagnosis and adherence to TB treatment. We conducted a qualitative study using group interviews with 11 groups of patients in three of the nine socioeconomic regions of the state of the Chiapas (Altos, Centro, and Fronteriza). The patients applied a variety of approaches in seeking care. The patients reported considerable delays in diagnosis due to problems that the patients themselves had and because of shortcomings in the care they received from the formal health care system. The treatment options that they followed were the result of their perceptions of the causes of TB and of the variety of traditional medical practices accepted in their communities. The lack of knowledge about TB encourages people to consider various alternatives for their care. Tuberculosis control in Chiapas requires an optimal utilization of the health services that exist in the state as well as a program of health education. TB control in Chiapas must take into account the social, cultural, and economic reality of the population.

  17. Integrating knowledge seeking into knowledge management models and frameworks

    Francois Lottering

    2012-02-01

    Full Text Available Background: A striking feature of the knowledge management (KM literature is that the standard list of KM processes either subsumes or overlooks the process of knowledge seeking. Knowledge seeking is manifestly under-theorised, making the need to address this gap in KM theory and practice clear and urgent.Objectives: This article investigates the theoretical status of the knowledge-seeking process in extant KM models and frameworks. It also statistically describes knowledge seeking and knowledge sharing practices in a sample of South African companies. Using this data, it proposes a KM model based on knowledge seeking.Method: Knowledge seeking is traced in a number of KM models and frameworks with a specific focus on Han Lai and Margaret Graham’s adapted KM cycle model, which separates knowledge seeking from knowledge sharing. This empirical investigation used a questionnaire to examine knowledge seeking and knowledge sharing practices in a sample of South African companies.Results: This article critiqued and elaborated on the adapted KM cycle model of Lai and Graham. It identified some of the key features of knowledge seeking practices in the workplace. It showed that knowledge seeking and sharing are human-centric actions and that seeking knowledge uses trust and loyalty as its basis. It also showed that one cannot separate knowledge seeking from knowledge sharing.Conclusion: The knowledge seeking-based KM model elaborates on Lai and Graham’s model. It provides insight into how and where people seek and share knowledge in the workplace. The article concludes that it is necessary to cement the place of knowledge seeking in KM models as well as frameworks and suggests that organisations should apply its findings to improving their knowledge management strategies.

    This paper explores perceived active health information seeking, informal advocacy by a partner or other, cardiac efficacy, and cardiovascular health indicators for patients surveyed while visiting their cardiologist. Participants include 208 patients with a diagnosed heart condition. Variables include predisposing characteristics (e.g., illness severity, demographics), perceived active health information seeking during an office visit, informal advocacy by partner or other, cardiac efficacy, and cardiovascular health indicators (i.e., basal metabolic index (BMI), total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides). Data were analyzed using correlations, t-tests, and structural equation modeling. As hypothesized, perceived active health information seeking during an office visit (positively) and informal advocacy by partner or other (negatively) predicted cardiac efficacy. One path was added from active information seeking to BMI. Cardiac efficacy, in turn, significantly predicted total cholesterol and BMI. The model was also replicated for LDLs but not for HDLs or triglycerides. We discuss implications for cardiac disease management.

    The dopamine system has been implicated in both substance use disorder (SUD) and schizophrenia. A recent meta- analysis suggests that A1 allele of the DRD2 gene imposes genetic risk for SUD, especially alcoholism and has been implicated in Reward Deficiency Syndrome (RDS). We hypothesize that dopamine D2 receptor (DRD2) gene Taq1 A2 allele is associated with a subtype of non- SUD schizophrenics and as such may act as a putative protective agent against the development of addiction to alcohol or other drugs of abuse. Schizophrenics with SUD may be carriers of the DRD2 Taq1 A1 allele, and/or other RDS reward polymorphisms and have hypodopaminergic reward function. One plausible mechanism for alcohol seeking in schizophrenics with SUD, based on previous research, may be a deficiency of gamma type endorphins that has been linked to schizophrenic type psychosis.. We also propose that alcohol seeking behavior in schizophrenics, may serve as a physiological self-healing process linked to the increased function of the gamma endorphins, thereby reducing abnormal dopaminergic activity at the nucleus accumbens (NAc). These hypotheses warrant further investigation and cautious interpretation. We, therefore, encourage research involving neuroimaging, genome wide association studies (GWAS), and epigenetic investigation into the relationship between neurogenetics and systems biology to unravel the role of dopamine in psychiatric illness and SUD.

    Nicotine dependence and its neural mechanisms have been well documented by pharmacological, behavioral and neuroscience studies. In this review, we introduce recent new findings in this theme, particularly on the role of nicotine -associated stimuli as non-pharmacological factors affecting maintaining/reinstating nicotine seeking. By using the techniques of drug self-administration and conditioned place preference, nicotine's specific property of forming seeking/taking behavior is well characterized, and the mechanisms of seeking/taking could be partly explained by discrete and/or contextual conditioned stimuli (dCS and cCS). After having the repeated Pavlovian conditioning in the training/conditioning sessions, CSs begin to play a key role for eliciting nicotine seeking behavior, with the activation of mesolimbic dopaminergic systems. In our study, intracranial self- stimulation (ICSS) was used to assess the mesolimbic dopamine activity. The nicotine-associated cCS also activated this neural system, which resulted in decreasing the ICSS threshold approximately 20% in the testing session under the cCS presentation. This finding would support the evidence of CS-induced incentive motivation for nicotine. According to the incentive salience hypothesis, the mesolimbic dopamine reflects the motivation elicited by incentives (CSs), and induces the drug seeking behavior, which is activated through amygdala--nucleus accumbens--medial prefrontal cortex circuit. Additionally, human brain imaging studies have revealed that tobacco- associated stimuli activate not only these regions, but also right temporo-parietal junction of human cortex, which is relevant to the visual attention. In summary, the above evidence shows that nicotine-conditioned stimuli might have powerful incentive salience and regulate nicotine seeking/taking behavior in animals and humans, though stress and nicotine-withdrawal could also enhance nicotine taking in the same way as other dependence -producing

    This study examined effects of age and social psychological factors on women's willingness to be mobile health information seekers. A national survey of 1,878 Singaporean women was conducted to obtain information on women's mobile phone usage, experiences of health information seeking, and appraisals of using mobile phones to seek health information. Results showed that young, middle-aged, and older women exhibited distinct mobile phone usage behaviors, health information-seeking patterns, and assessments of mobile health information seeking. Factors that accounted for their mobile information-seeking intention also varied. Data reported in this study provide insights into mobile health interventions in the future.

    In car renting, customer demands rental time are subject to random variation. Thus, it is difficult to model and optimize such a process. The car renting is treated as a real-time queuing process. Based on this concept, for a car rental company, aiming at maximizing its profit by determiriing the number of vehicles needed,a mathematical model is developed. With this model, the profit obtained by two companies under cooperation is compared with that obtained without cooperation. Results show that more profit can be obtained with cooperation than without cooperation.

    2016-01-01

    The aim of this study was to test social mentality theory, which views self-compassion/reassurance as a form of intrapersonal relating in which the interpersonal mentalities of care-seeking and caregiving are activated. Self-report measures of motivations, cognitions, and behaviors related to seeking and receiving care from others were administered to 195 students. Self-compassion/reassurance was predicted by the interaction of care-seeking and caregiving, with the positive effect of care-seeking intensified at high caregiving. As hypothesized, the combination of high care-seeking and high caregiving predicted the highest level of self-compassion/reassurance. The lowest level of self-compassion/reassurance was predicted by the combination of low care-seeking and high caregiving consistent with the concept of compulsive caregiving. Findings suggest that fostering a kinder way of relating to oneself may be achieved through more effective care-seeking and caregiving with others.

    Novelty-seeking tendencies in adolescents may promote innovation as well as problematic impulsive behaviour, including drug abuse. Previous research has not clarified whether neural hyper- or hypo-responsiveness to anticipated rewards promotes vulnerability in these individuals. Here we use a longitudinal design to track 144 novelty-seeking adolescents at age 14 and 16 to determine whether neural activity in response to anticipated rewards predicts problematic drug use. We find that diminished BOLD activity in mesolimbic (ventral striatal and midbrain) and prefrontal cortical (dorsolateral prefrontal cortex) regions during reward anticipation at age 14 predicts problematic drug use at age 16. Lower psychometric conscientiousness and steeper discounting of future rewards at age 14 also predicts problematic drug use at age 16, but the neural responses independently predict more variance than psychometric measures. Together, these findings suggest that diminished neural responses to anticipated rewards in novelty-seeking adolescents may increase vulnerability to future problematic drug use. PMID:28221370

    2016-03-01

    Anchored in the social organization theory of action and change, we use data from a large sample of active-duty Air Force members to examine the direct and indirect influence of social involvement and social responsibility on willingness to seek help in times of need via trust in formal systems and informal supports. Group comparisons are conducted between junior male, junior female, senior male, and senior female service members. The key mediational path in the model for all groups is the connection between social involvement and willingness to seek help via trust in formal systems. These results can inform both unit- and community-level interventions intended to increase the likelihood that active-duty AF members will seek help in times of need.

    Le présent document ne se veut pas un article de revue mais plutôt un élément d'initiation à une technique encore marginale en Biologie. Le lecteur est supposé être un non spécialiste de la diffusion de neutrons poursuivant une thématique à connotation biologique ou biophysique mettant en jeu des phénomènes dynamiques. En raison de la forte section de diffusion incohérente de l'atome d'hydrogène et de l'abondance de cet élément dans les protéines, la diffusion incohérente inélastique de neutrons est une technique irremplaçable pour sonder la dynamique interne des macromolécules biologiques. Après un rappel succinct des éléments théoriques de base, nous décrivons le fonctionnement de différents types de spectromètres inélastiques par temps de vol sur source continue ou pulsée et discutons leurs mérites respectifs. Les deux alternatives utilisées pour décrire la dynamique des protéines sont abordées: (i)l'une en termes de physique statistique, issue de la physique des verres, (ii) la seconde est une interprétation mécanistique. Nous montrons dans ce cas, comment mettre à profit les complémentarités de domaines en vecteur de diffusion et de résolution en énergie de différents spectromètres inélastiques de neutrons (temps de vol, backscattering et spin-écho) pour accéder, à l'aide d'un modèle physique simple, à la dynamique des protéines sur une échelle de temps allant d'une fraction de picoseconde à quelques nanosecondes.

    2007-09-01

    The gene encoding cathechol-O-methyltransferase (COMT) contains a common functional missense polymorphism (Val158Met) that regulates dopamine in an allele-dependent manner. A pivotal role of dopamine neurotransmission in the prefrontal cortex has been implicated in drug-seeking behavior and related personality traits, such as sensation seeking, with some evidence for a gender-specific association. Here, we tested the hypothesis that the COMT Val158Met polymorphism modulates the personality dimension, sensation seeking, in a gender-dependent manner. Study sample included 214 male (age 38.1+/-12.6 years) and 218 female (age 36.1+/-13.6 years) healthy volunteers, who were assessed with Zuckerman's sensation-seeking scale and genotyped for the Val158Met polymorphism (dbSNP:rs4680). Univariate analysis of variance showed that the sensation seeking score was significantly affected by a COMT genotype x gender interaction (F=5.330, df=2, p=0.005). The Val158Met polymorphism was associated with the sensation seeking personality trait in women only. The highest scores in the sensation-seeking scale and in three of the four subscales were observed in female subjects with the Val/Val genotype relative to women carrying the Met allele. Our results suggest that high COMT enzyme activity associated with the Val allele predisposes to high sensation seeking scores in female subjects and add to increasing evidence for a gender specific role of COMT in normal and dysfunctional behavior.

    2012-01-01

    Traditional healing is a common practice in low and middle income countries such as Malaysia. Eighty percent of Malaysians consult traditional healers or "bomoh" at some time in their life for health-related issues. The purpose of our study was to explore why breast cancer patients visit traditional healers. This is a qualitative study utilizing in-depth interviews with 11 cancer survivors who sought both traditional and Western medicine. The findings revealed the following reasons for which patients seek traditional healers: (1) recommendation from family and friends, (2) sanction from family, (3) perceived benefit and compatibility, (4) healer credibility, and (5) reservation with Western medicine and system delay. These factors work together and are strongly influenced by the Malaysian cultural context. The issue with the Western health system is common in a developing country with limited health facilities.

  16. Seeking for Simplicity in Complex Networks

    CERN Document Server

    Costa, L F

    2007-01-01

    Complex networks can be understood as graphs whose connectivity deviates from those of regular or near-regular graphs (which can be understood as `simple'). While a great deal of the attention so far foressen for complex networks has been duly driven by the above principle, in this work we take the dual approach and address the identification of simplicity, in the sense of regularity, in complex networks. The basic idea is to seek for subgraphs exhibiting small dispersion (e.g. standard deviation or entropy) of local measurements such as the node degree and clustering coefficient. Here we consider two types of subgraphs: (a) those defined by the progressive neighborhoods around each node and (b) subgraphs obtained from sets of nodes presenting similar local measurements. The former approach allows the assignment of a hierarchical regularity index to all network nodes, the latter paves the way for the identification of subgraphs (patches) in the original network, with nearly uniform connectivity. We illustrate...

  17. New wave seeks Indonesian coal mining concessions

    Energy Technology Data Exchange (ETDEWEB)

    Symon, A.

    1996-03-01

    A further wave of new mine exploration and development is on the horizon in Indonesia with 40 companies seeking major new concessions. Successful companies will enjoy a more attractive regulatory framework than their predecessors. The Indonesian Government is recasting the terms of the agreements under which it allows private domestic and foreign invested companies to operate large scale operations in order to encourage more investment in the industry. The Government`s intent to encourage expansion of the industry reflects looming pressure to provide sufficient coal to meet ambitious power plant expansion plans, while being able to maintain coal`s now important role as an export earner. In 1995, steam coal exports reached 40 billion tonnes, and contributed more than 1 billion dollars to Indonesia`s trade accounts. With Indonesia facing a widening current account deficit - combined with high foreign debt - the coal industry is playing a not insignificant role in helping to stabilise Indonesia`s external accounts. 1 tab.

    CERN Document Server

    Scheinker, Alexander

    2017-01-01

    With this brief, the authors present algorithms for model-free stabilization of unstable dynamic systems. An extremum-seeking algorithm assigns the role of a cost function to the dynamic system’s control Lyapunov function (clf) aiming at its minimization. The minimization of the clf drives the clf to zero and achieves asymptotic stabilization. This approach does not rely on, or require knowledge of, the system model. Instead, it employs periodic perturbation signals, along with the clf. The same effect is achieved as by using clf-based feedback laws that profit from modeling knowledge, but in a time-average sense. Rather than use integrals of the systems vector field, we employ Lie-bracket-based (i.e., derivative-based) averaging. The brief contains numerous examples and applications, including examples with unknown control directions and experiments with charged particle accelerators. It is intended for theoretical control engineers and mathematicians, and practitioners working in various industrial areas ...

  20. Seeking prospects for enhanced gas recovery

    Energy Technology Data Exchange (ETDEWEB)

    Doherty, M.G.; Randolph, P.L.

    1982-01-01

    As part of the Institute of Gas Technology's (IGT) ongoing research on unconventional natural gas sources, a methodology to locate gas wells that had watered-out under over-pressured conditions was developed and implemented. Each year several trillion cubic feet (Tcf) of gas are produced from reservoirs that are basically geopressured aquifers with large gas caps. As the gas is produced, the gas-water interface moves upward in the sandstone body trapping a portion of gas at the producing reservoir pressure. The methodology for identifying such formations consisted of a computer search of a large data base using a series of screening criteria to select or reject wells. The screening criteria consisted of depth cutoff, minimum production volume, minimum pressure gradient, and minimum water production. Wells chosen by the computer search were further screened manually to seek out those wells that exhibited rapid and large increases in water production with an associated quick decline in gas production indicating possible imbibition trapping of gas in the reservoir. The search was performed in an attempt to characterize the watered-out geopressured gas cap resource. Over 475 wells in the Gulf Coast area of Louisiana and Texas were identified as possible candidates representing an estimated potential of up to about 1 Tcf (2.83 x 10/sup 10/ m/sup 3/) of gas production through enhanced recovery operations. A process to determine the suitability of a watered-out geopressured gas cap reservoir for application of enhanced recovery is outlined. This paper addresses the identification of a potential gas source that is considered an unconventional resource. The methodology developed to identify watered-out geopressured gas cap wells can be utilized in seeking other types of watered-out gas reservoirs with the appropriate changes in the screening criteria. 12 references, 2 figures, 5 tables.

  2. Information Seeking & Documentation as Communication: A Software Engineering Perspective

    Directory of Open Access Journals (Sweden)

    Michael O'Brien

    2015-02-01

    Full Text Available Effective communication of knowledge is paramount in every software organisation. Essentially, the role of documentation in a software engineering context is to communicate information and knowledge of the system it describes. Unfortunately, the current perception of documentation is that it is outdated, irrelevant and incomplete. Several studies to date have revealed that documentation is unfortunately often far from ideal. Problems tend to be diverse, ranging from incompleteness, to lack of clarity, to inaccuracy, obsolescence, difficulty of access, and lack of availability in local languages. This paper begins with a discussion of information seeking as an appropriate perspective for studying software maintenance activities. To this end, it examines the importance and centrality of documentation in this process. It finally concludes with a discussion on how software documentation practices can be improved to ensure software engineers communicate more effectively via the wide variety of documents that their projects require.

Method: One hundred eighteen aged care recipients were surveyed on their beliefs about the helpfulness of a variety of treatments/interventions for depression, on their actual help-seeking behaviors, and on their experience of depression (current and past. Results: From the sample, 32.4% of the participants screened positive for depression on the Geriatric Depression Scale, and of these, 24.2% reported receiving treatment. Respondents believed the most helpful treatments for depression were increasing physical activity, counseling, and antidepressant medication. Help-seeking from both professional and informal sources appeared to be related to belief in the helpfulness of counseling and antidepressants; in addition, help-seeking from informal sources was also related to belief in the helpfulness of sleeping tablets and reading self-help books. In univariate analyses, lower levels of cognitive impairment and being in the two lower age tertiles predicted a greater likelihood of help-seeking from professional sources, and female sex and being in the lower two age tertiles predicted greater likelihood of help-seeking from informal sources. In multivariate analyses, only lower levels of cognitive impairment remained a significant predictor of help-seeking from professional sources, whereas both lower age and female sex continued to predict a greater likelihood of help-seeking

    To explore adolescent health seeking behavior during pregnancy and early motherhood in order to contribute to health policy formulation and improved access to health care. This will in long-term have an impact on the reduction of morbidity and mortality among adolescent mothers and their newborns. This was a qualitative study that employed focus group discussions (FGDs) among adolescent girls (10-19 years) and key informant (KI) interviews with health workers. Age for FGD participants ranged from 16 to 19 years. The FGD participants were recruited while seeking antenatal care for their first pregnancy or immunization service for their first child, not being older than 6 months. Six health facilities were selected. Key informants were purposefully selected on the basis of being in-charge of maternity units. Thirteen FGDs comprising of a total of 92 adolescent girls were conducted. The FGDs were held with homogeneously constituted categories; married pregnant adolescents (5), unmarried pregnant adolescents (3) and married or not married adolescents with children (5). Semi structured interviews were held with six KIs who were in-charge of maternity units of health facilities. Latent content analysis technique was used for data analysis. Two main themes emerged; 'feeling exposed and powerless', and 'seeking safety and empathy'. The categories identified in the first theme were "the dilemma of becoming an adolescent mother" and "lack of decision power". In the second theme the following categories were identified: "cultural practices and beliefs about birth", "expectations and experiences", "transport, a key determinant to health seeking", and "dealing with constraints". Adolescents felt exposed and powerless due to the dilemma of early motherhood and lack of decision making power. The adolescent mothers seemed to be in continuous quest for safety and empathy. In so doing they are part of cultural practices and beliefs about birth. They had expectations about the health

    Preventive strategies are known to reduce cancer risk and incidence and improve prognosis. Men seldom seek medical information about cancer prevention and risk reduction. The aim of this meta-narrative systematic review was to critically appraise evidence from qualitative, quantitative, and mixed-methods studies that explored men's information-seeking behaviors in relation to cancer prevention and risk reduction. MEDLINE, CINAHL Plus with Full Text, PsycINFO, PsycARTICLES, Psychology and Behavioral Sciences Collection, Education Full Text, and ERIC were systematically searched for studies published in English between January 1, 2006 and May 30, 2016. A total of 4117 titles were identified; of which, 31 studies were included (21 qualitative studies, 9 quantitative studies, and 1 mixed-methods study). The methodological quality of the studies was appraised by using different tools. Most studies focused on screening for prostate (n = 18) and colorectal cancer (n = 7). Most men were passive information-gatherers rather than active information-seekers. Key sources of information included the Internet for active information-seekers and health care professionals for passive information-gatherers. Barriers to information-seeking included information overload, embarrassment, and fear. Low literacy and health literacy levels were addressed in 3 studies and were identified as impediments to active information-seeking. Facilitators to information-seeking included family support, media, celebrity endorsements, and targeted information. Men's information-seeking behavior regarding cancer risk reduction, prevention, and screening is influenced by several factors. This necessitates targeted interventions aimed at raising awareness of cancer prevention and screening, while accounting for men's informational needs, preferred learning strategies, and literacy levels.

    Full Text Available Diarrhea remains one of the major causes of death in Bangladesh. We studied diarrheal disease risk and healthcare seeking behavior among populations at high risk for diarrhea in Dhaka, Bangladesh. Data were obtained from a cross-sectional survey conducted during April and September 2010. The prevalence of diarrhea was calculated by age-group and sex. A generalized estimating equation with logit link function was used to predict diarrheal disease risk and seeking care from a professional healthcare provider. Of 316,766 individuals, 10% were young children (<5 years. The prevalence of diarrhea was 16 per 1000 persons among all ages; young children accounted for 44 per 1000 persons. Prevalence of diarrhea was significantly higher (p=.003 among younger males (<15 years compared to that among younger females. In contrast, prevalence of diarrhea was significantly higher (p<.0001 among older females (≥15 years compared to that among older males. An increased risk for diarrhea was observed in young children, males, and those staying in rented houses, lower family members in the house, using non-sanitary toilets, living in the area for short times, living in a community with less educated persons, living in a community with less use of safe water source for drinking, or living close to the hospital. About 80% of those with diarrhea sought care initially from a non-professional healthcare provider. Choice of the professional healthcare provider was driven by age of the patient, educational status of the household head, and hygienic practices by the household. The study reaffirms that young children are at greater risk for diarrhea. Like other developing countries most people in this impoverished setting of Dhaka are less likely to seek care from a professional healthcare provider than from a non-professional healthcare provider, which could be attributed to a higher number of diarrheal deaths among young children in Bangladesh.

    Objective To investigate the changes of telemetry electrical activity in the infralimbic cortex (IL) of morphine-dependent rats with extinguished drug-seeking behavior. Methods SD rats were randomly divided into model group and control group and received operations of brain stereotaxic electrode embedding in the IL. The rats in the model group were induced to acquire morphine dependence and then received subsequent extinction training, and the changes of electrical activity in the IL were recorded with a physical wireless telemetry system. Results In rats with morphine dependence, the time staying in the white box was significantly longer on days 1 and 2 after withdrawal than that before morphine injection and that of the control rats, but was obviously reduced on days 1 and 2 after extinction training to the control level. Compared with the control group, the morphine-dependent rats on day 2 following withdrawal showed significantly increased β wave and decreased δ wave when they stayed in the white box but significantly increased δ wave and decreased α wave and β wave when they shuttled from the black to the white box. On day 2 of extinction, the model rats, when staying in the white box, showed significantly decreasedθwave compared with that of the control rats group but decreasedβwave andθwave and increasedδwave compared with those in the withdrawal period. When they shuttled from black to white box, the model rats showed decreased δ wave and increased α wave and β wave compared with those in the withdrawal period. Conclusion Morphine-dependent rats have abnormal changes of electrical activity in the IL in drug-seeking extinction to affect their drug-seeking motive and inhibit the expression and maintenance of drug-seeking behaviors.%目的:探讨吗啡依赖大鼠觅药消退期边缘下区(infralimbic cortex, IL)遥测脑电活动的变化对觅药行为的影响及其机制。方法将SD大鼠随机分成模型组和对照组,在IL区实

    Full Text Available Abstract Background Post-treatment follow-up visits for gynecological cancer survivors should provide opportunities for management of adverse physical/psychological effects of therapy and early recurrence detection. However, the adequacy of such visits in Japan is poorly documented. We qualitatively explored care-seeking experiences of Japanese gynecological cancer survivors and deduced factors influencing care-seeking behaviors and treatment access. Methods We conducted 4 semi-structured focus groups comprising altogether 28 Japanese gynecological cancer survivors to collect a variety of participants’ post-treatment care-seeking behaviors through active interaction with participants. Factors influencing access to treatment for adverse effects were analyzed qualitatively. Results Survivors sought care through specialty clinic visits when regular post-treatment gynecological follow-ups were inadequate or when symptoms seemed to be non-treatment related. Information provided by hospital staff during initial treatment influenced patients’ understanding and response to adverse effects. Lack of knowledge and inaccurate symptom interpretation delayed help-seeking, exacerbating symptoms. Gynecologists’ attitudes during follow-ups frequently led survivors to cope with symptoms on their own. Information from mass media, Internet, and support groups helped patients understand symptoms and facilitated care seeking. Conclusions Post-treatment adverse effects are often untreated during follow-up visits. Awareness of possible post-treatment adverse effects is important for gynecological cancer survivors in order to obtain appropriate care if the need arises. Consultation during the follow-up visit is essential for continuity in care.

    Full Text Available Introduction. Women are active information seekers, particularly in the context of managing health for themselves and their families. Rural living may present particular challenges and opportunities for women in their health information seeking. Method. Forty women living in a rural part of Ontario, Canada were interviewed using a semi-structured interview guide. They were asked about their health information seeking for both chronic and acute concerns. Analysis. Interview transcripts were organized using NVivo software (version 6 and analysed using a coding scheme iteratively developed by both authors. Results. Emerging themes included: the context of rural living, information and health literacy, the role of unanticipated information intermediaries in the search process, and the mis-match between assumptions made by 'the system' about sources of information, and women's lived realities. Conclusion. . There are unique challenges and enablers to health information seeking for women living in rural areas, including the role of formal, informal and ICT-based information intermediaries, the availability to women of required literacies for health information seeking and uptake. Research findings such as those presented in this paper can assist in better understanding both the contexts of information seeking, as well as the preferences and behaviour of those with information needs.

  16. The Roles of Dopamine and Related Compounds in Reward-Seeking Behavior Across Animal Phyla

    Barron, Andrew B.; Søvik, Eirik; Cornish, Jennifer L.

    2010-01-01

    Motile animals actively seek out and gather resources they find rewarding, and this is an extremely powerful organizer and motivator of animal behavior. Mammalian studies have revealed interconnected neurobiological systems for reward learning, reward assessment, reinforcement and reward-seeking; all involving the biogenic amine dopamine. The neurobiology of reward-seeking behavioral systems is less well understood in invertebrates, but in many diverse invertebrate groups, reward learning and responses to food rewards also involve dopamine. The obvious exceptions are the arthropods in which the chemically related biogenic amine octopamine has a greater effect on reward learning and reinforcement than dopamine. Here we review the functions of these biogenic amines in behavioral responses to rewards in different animal groups, and discuss these findings in an evolutionary context. PMID:21048897

  17. The glassy sweepers' way: seeking a versatile wrasse to be cleaned

    Directory of Open Access Journals (Sweden)

    Cristina Sazima

    Full Text Available Diurnal reef fishes compose the bulk of clients that seek cleaner fishes' services, but some nocturnal species that shelter at daytime also seek the cleaners. While doing so the nocturnal clients must leave their hiding places and thus they get exposed to potential diurnal predators. We report here on the cleaning interactions between a daytime cleaner wrasse (Thalassoma noronhanum and a night time active client (Pempheris schomburgki that usually remains sheltered at daytime. We recorded P. schomburgki leaving their shelter at daytime and heading towards T. noronhanum, whenever the cleaner swam by the shelter. Since T. noronhanum is able to tend temporary cleaning station near the safety of the shelters of its clients, P. schomburgki lessens a possible risk of predation by seeking this versatile cleaner.

Institutional theory suggests that MNCs need to conform to the prevailing rules, norms and procedures of the locations where they operate in order to survive and grow. This means that MNCs need to develop the best possible configuration of strategy-structure for their worldwide operations. Previous research has noted that in these conditions firms may simply seek to follow a referent other. However, MNCs’ specific strategy for a focal foreign operation is likely to determine the entry mode for each host country. In certain circumstances it may be whether MNCs are pursuing a market-seeking strategy or a strategic resource seeking strategy that shapes the entry mode in face of the prevailing institutional pressures. We contribute to the understanding of entry modes into foreign markets as a reflection of a strategic choice that is bound by institutional constraints.

    This article seeks to deepen understanding of the reasons that abused women in a resource-poor rural setting seek recourse so seldom and with so little success. Data from in-depth interviews and group discussions are used to explore the range of responses to domestic violence and to examine barriers to recourse seeking. Findings illustrate how the combination of poverty and gender inequality, inequities in the legal framework, and patriarchal attitudes and corruption in both formal and informal institutions at the local level discourage abused women from seeking recourse and decrease the likelihood of a favorable outcome when they do.

    Individuals with genotypes that code for reduced dopaminergic brain activity often exhibit a predisposition toward aggression. However, it remains largely unknown how dopaminergic genotypes may increase aggression. Lower-functioning dopamine systems motivate individuals to seek reward from external sources such as illicit drugs and other risky experiences. Based on emerging evidence that aggression is a rewarding experience, we predicted that the effect of lower-functioning dopaminergic functioning on aggression would be mediated by tendencies to seek the environment for rewards. Caucasian female and male undergraduates (N = 277) were genotyped for five polymorphisms of the dopamine D2 receptor (DRD2) gene; they reported their previous history of aggression and their dispositional reward-seeking. Lower-functioning DRD2 profiles were associated with greater sensation-seeking, which then predicted greater aggression. Our findings suggest that lower-functioning dopaminergic activity puts individuals at risk for violence because it motivates them to experience aggression's hedonically rewarding qualities.

    Musculoskeletal pain is common among adolescents, but little is known about the factors that affect seeking health care for the problem. We examined the care-seeking pattern among adolescents reporting musculoskeletal pain. The study consisted of adolescents aged 16 years from the 1986 Northern Finland Birth Cohort who responded to a mailed questionnaire in 2001 and reported musculoskeletal pain over the preceding 6 months (n=5052). Logistic regression analyses were performed to assess whether enabling resources, need factors, personal health habits, and psychological problems were associated with seeking health care for musculoskeletal pain. Musculoskeletal pain during the preceding 6 months was reported by 68% of boys and 83% of girls in the study population. Only 16% of boys and 20% of girls reporting pain had sought medical care. Among both boys and girls, care-seeking was associated with being a member of a sports club (boys, odds ratio [OR] 2.1; girls, OR 1.5) and having one (boys, OR 2.1; girls, OR 1.8) or at least 2 (boys, OR 2.2; girls, OR 2.1) other health disorders. In addition, it was associated with a high physical activity level (OR 1.5) and low self-rated (OR 1.5) health among girls. Reporting pain in other anatomical areas decreased the likelihood of seeking care for pain among both genders. In conclusion, relatively few adolescents with musculoskeletal pain had consulted a health professional for the problem. Being physically active (trauma), participating in organized sport (accessibility of care), and having other health problems may explain why an adolescent seeks care for musculoskeletal pain.

    The desire to engage with others is an important motivational force throughout our lifespan. It is known that social behaviour and preferences change from childhood to adulthood, but whether this change is linked with any changes in social motivation is not known. We evaluated 255 typically developing participants from ages 4-20 years on a behavioural paradigm 'Choose a Movie' (CAM). On every trial, participants had a choice between viewing social or non-social movies presented with different levels of effort (key presses/screen touch required). Hence, participants chose not only the movie they would watch but also how much effort they would make. The difference between the effort levels of the chosen and not chosen stimuli helps in quantifying the motivation to seek it. This task could be used with all the age groups with minimal adaptations, allowing comparison between the groups. Results showed that children (4-8 years), older adolescents (12-16 years) and young adults (17-20 years) made more effort to look at social movies. Counterintuitively, this preference was not seen in young adolescents (around 9-12 years), giving a U-shaped developmental trajectory over the population. We present the first evidence for non-monotonic developmental change in social motivation in typical participants.

Firstly, this paper reviews two classical models, and points out their application conditions and limitations. Then, the author studies housing rent-to-price ratio from annual cost of ownership (owner cost), and build up corresponding model. Using this model, the paper analyzes the causes that housing rent-to-price ratio exceeds 1:300, at the same time, puts forward the trend of housing rent-to-price ratio in China and effective measures to depress rent-to-price ratio.

  5. The SEEKING mind: primal neuro-affective substrates for appetitive incentive states and their pathological dynamics in addictions and depression.

    Science.gov (United States)

    Alcaro, Antonio; Panksepp, Jaak

    2011-10-01

    Appetitive motivation and incentive states are essential functions sustained by a common emotional brain process, the SEEKING disposition, which drives explorative and approach behaviors, sustains goal-directed activity, promotes anticipatory cognitions, and evokes feelings of positive excitement which control reward-learning. All such functions are orchestrated by the same "archetypical" neural processes, activated in ancient subcortical areas and transported to the forebrain by the mesolimbic dopamine (ML-DA) system. In mammals, the neurophysiology of the SEEKING urge is expressed by DA-promoted high-frequency oscillations, in the form of transient and synchronized gamma waves (>30Hz) emerging in limbic forebrain and diffusing throughout basal ganglia-thalamocortical (BG-T-C) circuits. These patterns may be considered basic "SEEKING neurodynamic impulses" which represent the primary-process exploratory disposition getting integrated with information relative to the external and the internal environment. Abnormal manifestation of SEEKING and its neural substrates are evident in clinical depression and addiction. Specifically, depression is characterized by reduced recruitment of SEEKING, while addictions reflect re-organizations of the SEEKING disposition around ultra-specific appetitive memories and compulsive activities.

    The amount of cancer-related information available to the general population continues to grow; yet, its effects are unclear. This study extends previous cross-sectional research establishing that cancer information seeking across a variety of sources is extensive and positively associated with engaging in health-related behaviors. The authors studied how active information seeking about cancer prevention influenced three healthy lifestyle behaviors using a 2-round nationally representative sample of adults ages 40-70 years (n = 1,795), using propensity scoring to control for potential confounders including baseline behavior. The adjusted odds of dieting at follow-up were 1.51 (95% CI: 1.05, 2.19) times higher for those who reported baseline seeking from media and interpersonal sources relative to nonseekers. Baseline seekers ate 0.59 (95% CI: 0.28, 0.91) more fruits and vegetable servings per day and exercised 0.36 (95% CI: 0.12, 0.60) more days per week at 1-year follow-up compared with nonseekers. The effects of seeking from media and friends/family on eating fruits and vegetables and exercising were independent of seeking from physicians. The authors offer several explanations for why information seeking predicts healthy lifestyle behaviors: information obtained motivates these behaviors; information sought teaches specific techniques; and the act of information seeking may reinforce a psychological commitment to dieting, eating fruits and vegetables, and exercising.

    2006-01-01

    Full Text Available Introduction. This paper investigates the ways in which spatial factors have been approached in information seeking studies. The main attention was focused on studies discussing information seeking on the level of source selection and use. Method. Conceptual analysis of about 100 articles and books thematizing spatial issues of information seeking. Due to research economy, the main attention was paid to studies on everyday life information seeking. Results. Three major viewpoints were identified with regard to the degree of objectivity of spatial factors. The objectifying approach conceives of spatial factors as external and entity-like qualifiers that primarly constrain information seeking. The realistic-pragmatic approach emphasizes the ways in which the availabilty of information sources in different places such as daily work environments orient information seeking. The perspectivist approach focuses on how people subjectively assess the significance of various sources by means of spatial constructs such as information horizons. Conclusion. Spatial factors are centrally important contextual qualifiers of information seeking. There is a need to further explore the potential of the above viewpoints by relating the spatial and temporal factors of information seeking.

    Full Text Available The current study had two main objectives. The first was to investigate Botswana’s university students’ intentions to seek psychological help. The second was to investigate whether (a Attitude Toward Seeking Professional Psychological Help (ATSPPH, (b Self-Stigma of Seeking Help (SSOSH, and (c Social Stigma of Receiving Psychological Help (SSRPH predicted the students’ intentions to seek psychological help. A total of N = 519 (283 females and 236 males students from the University of Botswana completed the survey. Results indicated that generally, the students had moderate intentions of seeking psychological help. Multiple regression analysis revealed that of the three predictors, only ATSPPH and SSRPH significantly predicted intentions to seek psychological help. The current study is important because while it has been established that university students are a high-risk population for mental health problems, there is close to nothing documented on university students in Botswana. Findings of the current study will undoubtedly increase knowledge relating to psychological help-seeking and its predictors in Botswana and may inform interventions that aim to encourage young people to seek psychological or counseling help.

    To determine whether perceived medication use knowledge held and/or needed influenced intention to seek information from pharmacists, whether an information-intention relationship held after accounting for other variables, and whether asking medication use knowledge questions increased pharmacist information-seeking intention. Cross-sectional study. SETTING United States during July 2012. Qualtrics national panel members 21 years or older obtaining a new chronic medication within previous 30 days. Internet-administered survey. Medication information-seeking intention, medication knowledge held and needed, and pharmacist medication information-seeking intention. Although knowledge held and needed were initially significant, they became nonsignificant after adding affective and evaluative attitudes, perceived control, and risk. The final best-fitting model explained 21% of variance in pharmacist information-seeking intention. Patient intentions to seek information from pharmacists increased significantly after being asked medication use knowledge questions. Perceptions of medication risk, attitudes, and information-seeking control predict pharmacist information-seeking intention and offer pharmacists an opportunity to market information services.

    Novelty preference or sensation seeking is associated with disorders of addiction and predicts rodent compulsive drug use and adolescent binge drinking in humans. Novelty has also been shown to influence choice in the context of uncertainty and reward processing. Here we introduce a novel or familiar neutral face stimuli and investigate its influence on risk-taking choices in healthy volunteers. We focus on behavioural outcomes and imaging correlates to the prime that might predict risk seeking. We hypothesized that subjects would be more risk seeking following a novel relative to familiar stimulus. We adapted a risk-taking task involving acceptance or rejection of a 50:50 choice of gain or loss that was preceded by a familiar (pre-test familiarization) or novel face prime. Neutral expression faces of males and females were used as primes. Twenty-four subjects were first tested behaviourally and then 18 scanned using a different variant of the same task under functional MRI. We show enhanced risk taking to both gain and loss anticipation following novel relative to familiar images and particularly for the low gain condition. Greater risk taking behaviour and self-reported exploratory behaviours was predicted by greater right ventral putaminal activity to novel versus familiar contexts. Social novelty appears to have a contextually enhancing effect on augmenting risky choices possibly mediated via ventral putaminal dopaminergic activity. Our findings link the observation that novelty preference and sensation seeking are important traits predicting the initiation and maintenance of risky behaviours, including substance and behavioural addictions.

    There is always a concern about bubble in the development of Chinese real estate market. Recently, with the increase of housing price, discussion in the regard is getting more attention. If the bubble bursts, it will cause great damage to Chinese economy and society. Thus, it has significant practical meaning to prevent real estate bubble. In this paper it analyzes the rent-sale price ratio in China. It indicates that the housing price in current China is too high; much of the housing demand is investment and speculation; and bubble exists in real estate market. In this paper,it further discusses the reasons of unbalanced rent-sale price ratio and puts forward some suggestions.%  我国房地产业发展历程充满着关于房地产泡沫的争论。近年来,随着房价的上涨,这种争论持续升温。房地产泡沫一旦发生,将给国家的经济和社会生活带来严重的后果,因此,防范房地产泡沫的发生具有重要的现实意义。本文通过对我国房屋租售比现状的分析,指出了我国住宅销售价格过高,住宅需求更多地体现为投资和投机的需求,住房价格中存在着泡沫。在此基础之上,本文就我国房屋租售比失调的成因进行了简要的讨论,并针对房地产市场宏观调控提出了一系列建议。

  15. Neural substrate of cold-seeking behavior in endotoxin shock.

    Directory of Open Access Journals (Sweden)

    Maria C Almeida

    Full Text Available Systemic inflammation is a leading cause of hospital death. Mild systemic inflammation is accompanied by warmth-seeking behavior (and fever, whereas severe inflammation is associated with cold-seeking behavior (and hypothermia. Both behaviors are adaptive. Which brain structures mediate which behavior is unknown. The involvement of hypothalamic structures, namely, the preoptic area (POA, paraventricular nucleus (PVH, or dorsomedial nucleus (DMH, in thermoregulatory behaviors associated with endotoxin (lipopolysaccharide [LPS]-induced systemic inflammation was studied in rats. The rats were allowed to select their thermal environment by freely moving in a thermogradient apparatus. A low intravenous dose of Escherichia coli LPS (10 microg/kg caused warmth-seeking behavior, whereas a high, shock-inducing dose (5,000 microg/kg caused cold-seeking behavior. Bilateral electrocoagulation of the PVH or DMH, but not of the POA, prevented this cold-seeking response. Lesioning the DMH with ibotenic acid, an excitotoxin that destroys neuronal bodies but spares fibers of passage, also prevented LPS-induced cold-seeking behavior; lesioning the PVH with ibotenate did not affect it. Lesion of no structure affected cold-seeking behavior induced by heat exposure or by pharmacological stimulation of the transient receptor potential (TRP vanilloid-1 channel ("warmth receptor". Nor did any lesion affect warmth-seeking behavior induced by a low dose of LPS, cold exposure, or pharmacological stimulation of the TRP melastatin-8 ("cold receptor". We conclude that LPS-induced cold-seeking response is mediated by neuronal bodies located in the DMH and neural fibers passing through the PVH. These are the first two landmarks on the map of the circuitry of cold-seeking behavior associated with endotoxin shock.

  16. The bed nucleus of the stria terminalis regulates ethanol-seeking behavior in mice.

    Drug-associated stimuli are considered important factors in relapse to drug use. In the absence of drug, these cues can trigger drug craving and drive subsequent drug seeking. One structure that has been implicated in this process is the bed nucleus of the stria terminalis (BNST), a chief component of the extended amygdala. Previous studies have established a role for the BNST in cue-induced cocaine seeking. However, it is unclear if the BNST underlies cue-induced seeking of other abused drugs such as ethanol. In the present set of experiments, BNST involvement in ethanol-seeking behavior was assessed in male DBA/2J mice using the conditioned place preference procedure (CPP). The BNST was inhibited during CPP expression using electrolytic lesions (Experiment 1), co-infusion of GABAA and GABAB receptor agonists muscimol and baclofen (M+B; Experiment 2), and activation of inhibitory designer receptors exclusively activated by designer drugs (hM4Di-DREADD) with clozapine-N-oxide (CNO; Experiment 3). The magnitude of ethanol CPP was reduced significantly by each of these techniques. Notably, infusion of M+B (Exp. 2) abolished CPP altogether. Follow-up studies to Exp. 3 showed that ethanol cue-induced c-Fos immunoreactivity in the BNST was reduced by hM4Di activation (Experiment 4) and in the absence of hM4Di, CNO did not affect ethanol CPP (Experiment 5). Combined, these findings demonstrate that the BNST is involved in the modulation of cue-induced ethanol-seeking behavior.

    High levels of stress and depression in medical students is raising concern. In this study, we sought to identify coping strategies and other factors influencing academic stress in medical students. We enrolled 157 students from the University of Ulsan College of Medicine, Korea, in November, 2010. We used the Medical Stress Scale, Temperament and Character Inventory, Hamilton Depression Scale, Beck Depression Inventory, and Coping Response Inventory to assess psychological parameters. We used Pearson's correlation and linear regression analyses to analyze the data. Novelty-seeking, self-directedness, cooperativeness, coping strategy, and depression scale scores all correlated significantly with stress level. Linear regression analysis indicated that students who are novelty-seeking, likely to use avoidant coping strategies, and unlikely to use active-cognitive and active-behavioral strategies tend to have higher stress levels. Reduction of stress in medical students may be achieved through evaluation of coping strategies and personality features and use of interventions to promote active coping strategies.

  19. Seeking Haven and Seeking Jobs: Migrant Workers’ Networks in Two Thai Locales

    2013-08-01

    Full Text Available Thailand has seen a large increase in migrant workers from Myanmar since the 1990s. A constant flow of migrants arrive to seek refuge from dire circumstances in their homeland and/or to seek better work opportunities. They have adapted to changing state policy regarding their migrant status and work permits as well as to more immediate means of control. Previous works on this subject have tended either toward macro-level policy and economics, or more journalistic accounts of individual migrant experiences. Little attention has been paid to differences in the migrant processes and networks formed across the border and within the country.  In this paper two locales, one on the border (Mae Sot and one in the interior (Samut Songkhram, are compared based on interviews conducted with migrant workers on their mode of arrival, living and working conditions, migrant status and control, and how they form networks and relations within and across the border. By comparing the two locales, rather than emphasize how the state and geopolitical space define mobility we argue that transnational migrant workers formulate and define their space through adaptive networks in articulation with geopolitical factors as well as local socioeconomic and historical-cultural dynamics. The dynamics among macro policies, micro-level agency of migrants, and meso-level networks define each locale.

  2. Extinction of drug seeking: Neural circuits and approaches to augmentation.

    Science.gov (United States)

    McNally, Gavan P

    2014-01-01

    Extinction training can reduce drug seeking behavior. This article reviews the neural circuits that contribute to extinction and approaches to enhancing the efficacy of extinction. Extinction of drug seeking depends on cortical-striatal-hypothalamic and cortical-hypothalamic-thalamic pathways. These pathways interface, in the hypothalamus and thalamus respectively, with the neural circuits controlling reinstatement of drug seeking. The actions of these pathways at lateral hypothalamic orexin neurons, and of perifornical/dorsomedial hypothalamic derived opioid peptides at kappa opioid receptors in the paraventricular thalamus, are important for inhibiting drug seeking. Despite effectively reducing or inhibiting drug seeking in the short term, extinguished drug seeking is prone to relapse. Three different strategies to augment extinction learning or retrieval are reviewed: pharmacological augmentation, retrieval - extinction training, and provision of extinction memory retrieval cues. These strategies have been used in animal models and with human drug users to enhance extinction or cue exposure treatments. They hold promise as novel strategies to promote abstinence from drug seeking. This article is part of a Special Issue entitled 'NIDA 40th Anniversary Issue'.

    It has been well established that pathways to care are considerably modified by local, social and psychological characteristics as well as the doctor-patient relationship. Scant attention has been paid to the role of family advice in care-seeking. In Omani society, traditional family values and a collective mindset are the norm rather than the exception. This paper examines how family advice affects the trajectory of care seeking. During 2006-2007, data was collected through face-to-face interviews among a randomised sample of patients seeking medical consultation in various primary health care centres in the northern region of Oman. This study enrolled a total of 493 patients. The association between the advice of family members as a reason to seek health care and other predictors was analysed using multivariable logistic regression. The data suggest that the advice of family members in care-seeking is strongly associated with gender, education, history of chronic illness, previous exposure to traditional medicine, and health education, as well as the history of immunisation. These findings suggest that the advice of family members remains a strong catalyst for care-seeking in Oman. The psychosocial factors affecting care-seeking leading to underutilisation of services or otherwise are discussed.

    2011-06-01

    Research shows runaway and homeless youth are reluctant to seek help from traditional health providers. The Internet can be useful in engaging this population and meeting their needs for sexual health information, including information about HIV and other sexually transmitted infections (STIs). Using a sample of homeless youth living in Los Angeles, California in June 2009, this study assesses the frequency with which runaway and homeless youth seek sexual health information via the Internet, and assesses which youth are more likely to engage in seeking health information from online sources. Drawing from Andersen's (1968) health behavior model and Pescosolido's (1992) network episode model, we develop and refine a model for seeking online sexual health information among homeless youth. Rather than testing the predicative strength of a given model, our aim is to identify and explore conceptually driven correlates that may shed light on the characteristics associated with these help seeking behaviors among homeless youth. Analyses using multivariate logistic regression models reveal that among the sample of youth, females and gay males most frequently seek sexual health information online. We demonstrate the structure of social network ties (e.g., connection with parents) and the content of interactions (e.g., e-mail forwards of health information) across ties are critical correlates of online sexual health information seeking. Results show a continued connection with parents via the Internet is significantly associated with youth seeking HIV or STI information. Similarly for content of interactions, more youth who were sent health information online also reported seeking HIV information and HIV-testing information. We discuss implications for intervention and practice, focusing on how the Internet may be used for dissemination of sexual health information and as a resource for social workers to link transient, runaway, and homeless youth to care.

    This paper presents the development and evaluation of the train-the-trainer (TTT) workshop for lay resident leaders to be lay health promoters. The TTT workshop aimed to prepare the trainees to implement and/or assist in conducting a series of community-based family well-being activities for the residents in a public low rent housing estate, entitled "Learning Families Project", under the FAMILY project. The four-hour TTT workshop was conducted for 32 trainees (72% women, 43% aged ≥ 60, 41% ≤ elementary school education). The workshop aimed to promote trainees' knowledge, self-efficacy, attitude and practice of incorporating the positive psychology themes into their community activities and engaging the residents to join these activities and learn with their family members. Post-training support was provided. The effectiveness of the TTT was examined by self-administered questionnaires about trainees' reactions to training content, changes in learning and practice at three time points (baseline, and immediately and one year after training), and the difference in residents' survey results before and after participating in the community activities delivered by the trainees. The trainees' learning about the general concepts of family well-being, learning family, leadership skills and planning skills increased significantly with medium to large effect sizes (Cohen's d: 0.5-1.4) immediately after the training. The effects of perceived knowledge and attitude towards practice were sustained to one year (Cohen's d: 0.4-0.6). The application of planning skills to implement community activities was higher at one year (Cohen's d: 0.4), compared with baseline. At one year, the residents' survey results showed significant increases in the practice of positive communication behaviours and better neighbour cohesions after joining the family well-being activities of LFP. Qualitative feedback supported the quantitative results. Our TTT workshop could serve as a practical

    Ecological land rent is an important indicator to measure the social-economic effect of ecological resources utilization. On the basis of input-output table and ecological footprint, the change of ecological land rent in China from 1997 to 2007 was analyzed. The result shows that, in this period, the ecological land rent in per unit economy output decreased, and the quantity of ecological land rent in per unit economy output of agriculture, forestry, animal husbandry and fishery, and production and supply of electric power, heat and water was much more than that of other industries. But the total number of ecological land rent still increased. And the ecological land rent of mining, quarrying and manufacturing industries, and that of agriculture, forestry, animal husbandry and fishery were the main constitute proportions. In the meantime, ecological land rent greatly transferred between different industries. With the numbers of 2007 as a control group, in which the parameters such as total output, ecological footprint, bio-capacity and agricultural land area changed, would cause a significant change in ecological land rent. Among this, the change of the ecological land rent in per unit economy output of agriculture, forestry, animal husbandry and fishery would be the most sensitive. Therefore, if considering the influence of ecological land rent, the price of consumption product will increase the most. This equals the high cost to be paid to improve the environment for excessive grabbing resources from nature by human.

    Online partner seeking is associated with sexual risk behavior among young adults (specifically men who have sex with men), but this association has yet to be explored among a probability sample of adolescents. Moreover, cell phone internet access and sexual risk taking online and offline have not been explored. A probability sample (N = 1,831) of Los Angeles Unified School District high school students was collected in 2011. Logistic regression models assessed relationships between specific sexual risk behaviors (online sexual solicitation, seeking partners online, sex with internet-met partners, condom use) and frequency of internet use, internet access points, and demographics. Students with cell phone internet access were more likely to report being solicited online for sex, being sexually active, and having sex with an internet-met partner. Bisexual-identifying students reported higher rates of being approached online for sex, being sexually active, and not using condoms at last sex. Gay, lesbian, and questioning (GLQ) students were more likely to report online partner seeking and unprotected sex at last sex with an internet-met partner. Additionally, having sex with an internet-met partner was associated with being male, online sexual solicitation, and online partner seeking. Internet- and school-based sexual health programs should incorporate safety messages regarding online sexual solicitation, seeking sex partners online, and engaging in safer sex practices with all partners. Programs must target adolescents of all sexual identities, as adolescents may not yet be "out," and bisexual and GLQ adolescents are more likely to engage in risky sex behaviors.

    Full Text Available Abstract Background Angelman syndrome (AS is a neurogenetic disorder characterized by severe developmental delay with mental retardation, a generally happy disposition, ataxia and characteristic behaviors such as inappropriate laughter, social-seeking behavior and hyperactivity. The majority of AS cases are due to loss of the maternal copy of the UBE3A gene. Maternal Ube3a deficiency (Ube3am-/p+, as well as complete loss of Ube3a expression (Ube3am-/p-, have been reproduced in the mouse model used here. Results Here we asked if two characteristic AS phenotypes - social-seeking behavior and hyperactivity - are reproduced in the Ube3a deficient mouse model of AS. We quantified social-seeking behavior as time spent in close proximity to a stranger mouse and activity as total time spent moving during exploration, movement speed and total length of the exploratory path. Mice of all three genotypes (Ube3am+/p+, Ube3am-/p+, Ube3am-/p- were tested and found to spend the same amount of time in close proximity to the stranger, indicating that Ube3a deficiency in mice does not result in increased social seeking behavior or social dis-inhibition. Also, Ube3a deficient mice were hypoactive compared to their wild-type littermates as shown by significantly lower levels of activity, slower movement velocities, shorter exploratory paths and a reduced exploratory range. Conclusions Although hyperactivity and social-seeking behavior are characteristic phenotypes of Angelman Syndrome in humans, the Ube3a deficient mouse model does not reproduce these phenotypes in comparison to their wild-type littermates. These phenotypic differences may be explained by differences in the size of the genetic defect as ~70% of AS patients have a deletion that includes several other genes surrounding the UBE3A locus.

    The objective of this study was to document barriers to care, help-seeking behaviors, and the impact of a community-based patient navigation intervention on patient activation levels among Bhutanese refugees in the U.S. Data sources comprised 35 intake and 34 post-intervention interviews with program participants, 14 intake and 14 post-intervention interviews with patient navigators, and 164 case notes. Textual data were analyzed using the constant comparison method. Patient activation level was assessed at both time points. Participants had limited English proficiency (97 %), limited literacy (69 %), and the lowest level of patient activation (69 %). Participants routinely experienced complex insurance access, coverage, and payment problems and had limited healthcare-related life skills. Help-seeking began within social networks, with high reliance on bilingual, literate family members perceived to have experience with "the system." Help-seeking was not stigmatized and was instead consistent with societal norms valuing mutual assistance. Participants preferred helpers to act as proxies and required repeated social modeling by peers to gain confidence applying healthcare-related life skills. Following the intervention, only one-third reported the lowest level of patient activation (35 %) and one-third were highly activated (32 %). Bhutanese refugees overcome healthcare access barriers by seeking help from a network of support that begins within the community. Community health workers serving as patient navigators are readily sought out, and this approach is concordant with cultural expectations for mutual assistance. Community health workers serving immigrant groups should model healthcare-related life skills in addition to providing direct assistance.

    Full Text Available Freezing has become the predominant measure used in rodent studies of conditioned fear, but conditioned suppression of reward-seeking behavior may provide a measure that is more relevant to human anxiety disorders; that is, a measure of how fear interferes with the enjoyment of pleasurable activities. Previous work has found that an isolated presentation of a fear conditioned stimulus prior to extinction training (retrieval + extinction results in a more robust and longer-lasting reduction in fear. The objective of this study was to assess whether the retrieval + extinction effect is evident using conditioned suppression of reward seeking, operationalized as a reduction in baseline licking (without prior water deprivation for a 10% sucrose solution. We found that, compared to freezing, conditioned suppression of reward seeking was much more sensitive to fear conditioning and far less responsive to extinction training. As in previous work, we found that retrieval + extinction reduced post-extinction fear reinstatement when measured as freezing, but it did not reduce fear reinstatement when measured as conditioned suppression. This suggests that there is still residual fear following retrieval + extinction, or that this procedure only modifies memory traces in neural circuits relevant to the expression of freezing, but not to the suppression of reward seeking.

    Although vaccinations are critical for preventing emerging infectious diseases, scant research has been conducted on risk communication. With socio-economic characteristics, health behavior, and underlying diseases under control, we investigated associations between media use, health information-seeking behavior, health information type, and vaccination in the population. This study relied on a national survey of Korean adults (n = 1367). Participants were adult males and females age 20 and older. Web and face-to-face surveys were conducted throughout July 2014. The main outcome was vaccination (categorized as yes or no). Independent variables were time spent on media, frequency of health information-seeking behavior, and types of health information sought. Controlling for co-variates, logistic regression analysis was conducted to identify factors that influence Korean adults being vaccinated. Results revealed that accessible information about emerging infectious diseases, listening to the radio, and reading the newspaper were associated with increased odds of being vaccinated. Active seeking health information as well as being female and of higher socio-economic status were positively correlated with Korean adults being vaccinated. It is critical to promote health information-seeking behavior and use diverse media channels to increase acceptance and awareness of emerging infectious diseases and vaccinations. Because there are differences in vaccination awareness depending on social class, it is critical to reduce communication inequality, strengthen accessibility to vaccinations, and devise appropriate risk communication strategies that ensure Korean adults receive vaccinations.

    PURPOSE Diabetes self-management is essential for diabetes control, yet little is known about patient preferences for sources of health information or about the extent to which information is sought directly or received passively through various media sources. The aim of this qualitative study was to identify how individuals with diabetes seek and use health care information. METHODS Using a health information model to guide our research, we conducted 9 focus groups with 46 adults with a diagnosis of diabetes and then analyzed the transcripts and notes from these focus groups. RESULTS Five themes emerged: (1) passive receipt of health information about diabetes is an important aspect of health information behavior; (2) patients weave their own information web depending on their disease trajectory; (3) patients’ personal relationships help them understand and use this information; (4) a relationship with a health care professional is needed to cope with complicated and sometimes conflicting information; and (5) health literacy makes a difference in patients’ ability to understand and use information. CONCLUSIONS Patients make decisions about diabetes self-management depending on their current needs, seeking and incorporating diverse information sources not traditionally viewed as providing health information. Based on our findings, we have developed a new health information model that reflects both the nonlinear nature of health information-seeking behavior and the interplay of both active information seeking and passive receipt of information.

    To describe the coping strategies and help-seeking behaviors of women and men with urinary incontinence (UI). In cross-sectional study, 156 women and 106 men Turkish with UI were interviewed using a questionnaire covering 29 questions. It was determined that 50.6% of women and 34.0% of men seek help in first for treatment of UI. Forty eight percent of men consulted a physician in the first 6 months after the UI occurred, 44.9% of women consulted a physician 2-5 years later after the UI occurred. Coping behaviors of both groups for management of the UI were as follows: keeping feet warm, performing hot application to perineum, reducing the amount of daily drinking water, using pad, cloth pads, restricting physical activity, refraining from social life and praying etc. While women mostly do not prefer to seek medical advice for UI, men tend to go to doctors more often than women. Except for treatment seeking behaviors, both men and women are practicing coping methods for the management of UI such as going frequently to the toilet, keeping feet warm, hot application to perineum etc. © 2015 Wiley Publishing Asia Pty Ltd.

    2007-06-13

    This article resumes the psychobiologic mechanisms involved in risk-seeking behaviour. The question is discussed whether some forms of high risk sports meet the diagnostic criteria of dependency. The intensive activation of the adrenocorticotropic pathway may yield to addiction: according to the model of emotion-focussed coping of stress, unpleasant emotion is "overwritten" by intense stress and hence better tolerated emotionally, leading to an addictive repetition of risk-seeking behaviour. In addition, pharmacologic mimicry seems possible as the perception of effects of catecholamines may imitate some of the effects of stimulating drugs. Finally, the current concept of risk and harm reduction is transferred to sports. This would mean to apply appropriate preventive interventions for a large variety of possibly dangerous activities.

    2012-06-01

    Full Text Available Survey method was used and 92 valid questionnaires were collected for the analyses. The results showed that the majority of the rural elder people expressed the need for and attention to health information. ‘‘health service information’’ and ‘‘prevention health care information’’ were the most needed and important. Family, friends and television were the main channels for accessing health information. However, fewer respondents actively sought health information. When health problems occurred, they tended to seek direct medical treatment. This study also found that men were more attentive and active in seeking health information. Respondents over 75 years old rarely concerned about their health information need. People with more education were also more aware of their health information needs and more attentive to information disseminated via mass media. [Article content in Chinese

    Reimann, Martin; Nenkov, Gergana Y; MacInnis, Deborah; Morrin, Maureen

    2014-12-01

    One construct validation study and four experiments showed that the relationship between hope and financial risk seeking depended on whether or not the possibility of a hoped-for outcome was threatened. Whereas high (vs. low) hope decreased financial risk seeking when the possibility of a hoped-for outcome was not threatened, high (vs. low) hope increased financial risk seeking when the outcome's possibility was threatened. These effects were observed in different contexts (i.e., gambling, stock investing, bidding, retirement investing), when applying different operationalizations of hope and threats to possibility, and when controlling for alternative explanations. We also showed that individuals' motivations to either achieve gains or avoid losses mediated the effects of hope on financial risk seeking. This research, which is the first to study the role of hope in financial decision making, adds to the extant literature by underscoring the psychological impact of threats to the possibility of attaining a hoped-for financial outcome.

  11. Role of Corticotropin Releasing Factor 1 Signaling in Cocaine Seeking during Early Extinction in Female and Male Rats.

    Directory of Open Access Journals (Sweden)

    Angie M Cason

    Full Text Available Locus coeruleus norepinephrine (LC-NE and corticotropin releasing factor (CRF neurons are involved in stress responses, including stress's ability to drive drug relapse. Previous animal studies indicate that female rats exhibit greater drug seeking than male rats during initial drug abstinence. Moreover, females are more sensitive to the effect of stress to drive drug seeking than males. Finally, LC-NE neurons are more sensitive to CRF in females compared to males. We hypothesized that increased drug seeking in females on extinction day one (ED1 is due to increased response to the stress of early withdrawal and is dependent upon the increased response of LC in females to CRF. We predicted that LC-NE neurons would exhibit Fos activation on ED1, and that blocking CRF1 signaling would decrease drug seeking on ED1 measured by responding on an active lever previously associated with cocaine self- administration. After chronic cocaine self-administration, female and male rats underwent a test for initial extinction responding by measuring lever pressing in the absence of cocaine. Prior to this Extinction Day 1 (ED1 session, rats were injected with vehicle or the selective CRF1 antagonist (CP to measure effects of CRF antagonism on drug seeking during early abstinence. ED1 increased corticosterone in female rats, in proportion to lever responding in male and female, indicating that ED1 was stressful. Pretreatment with CP decreased cocaine seeking on ED1 more effectively in female compared to male rats. This increase in responding was associated with an increase in activation of LC NE neurons. Together, these findings indicate that stress, and signaling at CRF receptors in LC, may be involved in the increased drug seeking during initial abstinence.

    2015-01-01

    Infant and under-five mortality rate in Nepal are 46 and 54 deaths per 1,000 live births, respectively. These mortality indicates, one in every 22 Nepalese children dies before reaching age 1, and one in every 19 does not survive to his or her fifth birthday. Delay in seeking appropriate care and not seeking any care contributes to the large number of child deaths. Existing interventions could prevent many deaths among children if they are presented at health facility and timely care. A descriptive research was carried out in Lele VDC, ward no.7, Lalitpur. The objective of this study was to find out health seeking behavior among mothers of sick children. Non probability, purposive sampling method was used. Sample size was 102 mothers who had sick children from 0 to 59 months. A set of semi structured questionnaire was used to obtain the data. The mean age of the respondent was 25.8 years and child was 29 months. Respondents' children who suffered with pneumonia, diarrhoea and malnutrition were 64(62.7%),29(28%), 9(8.8%) respectively. Majority 84(81.4%) mothers had sought treatment and among them 58(69%) sought treatment from health facility whereas 26(31%) sought treatment from traditional healer. There was significant relationship between education of the mother(p=0.05), sex of the child (p=0.004), type of sickness of children (p=0.001) of the mother and health seeking behaviour of mothers. However occupation of the mothers for seeking treatment (p=0.66) and treatment seeking at first (p=0.82) were not significant. So there was no relationship between occupation of the mothers and health seeking behaviour. Majority of the mothers sought treatment from health facility, yet around one fourth went at traditional healers. Education of the mother, sex of the child, sickness of child and mother's awareness are the factors affecting health seeking behavior of the mothers.

  16. Children's Attentional Processing of Mother and Proximity Seeking.

    Directory of Open Access Journals (Sweden)

    Guy Bosmans

    Full Text Available Attachment expectations regarding the availability of mother as a source for support are supposed to influence distressed children's support seeking behavior. Because research is needed to better understand the mechanisms related to support seeking behavior, this study tested the hypothesis that the cognitive processing of mother-related information is linked to proximity and support seeking behavior. Uncertainty in maternal support has been shown to be characterized by a biased attentional encoding of mother, reducing the breadth of children's attentional field around her. We investigated whether this attentional bias is related to how long distressed children wait before seeking their mother's proximity. Thirty-three children (9-11 years participated in this study that consisted of experimental tasks to measure attentional breadth and to observe proximity seeking behavior and of questionnaires to measure confidence in maternal support and experienced distress. Results suggested that distressed children with a more narrow attentional field around their mother wait longer to seek her proximity. Key Message: These findings provide a first support for the hypothesis that the attentional processing of mother is related to children's attachment behavior.

    2016-10-01

    Only a third of people with mental disorders seek professional help. In this study, we aimed to investigate attitudes toward help-seeking among non-help-seekers drawn from a community survey in South London. We conducted qualitative interviews with 24 participants with symptoms of mental disorders. We analyzed data using thematic analysis. Participants' reasons for not seeking professional help included perceiving their problems as normal or unsuitable for professional help, negative expectations of professional help, believing informal strategies were sufficient, fearing being stigmatized for having a mental disorder and help-seeking, and self-perceptions of being strong and/or self-reliant. A small number (n = 4) had resolved their problems. Participants with unresolved mental disorders (n = 20) had more chronic stressors, particularly about finances and family relationships, and greater concerns about professional help and stigma than other participants. Potential targets for interventions to encourage help-seeking could be focused around stigma about help-seeking as well as the self-perception of being strong.

    Full Text Available Objective: Some studies have found that high levels of impulsivity and sensation seeking, particularly disinhibition are associated with substance abuse in patients with schizophrenia, as in the general population. However, no study has assessed impulsivity and sensation seeking specifically in schizophrenia patients with alcohol abuse or dependence. Material and Methods: We compared impulsivity and sensation seeking in a group of schizophrenia patients (DSM-III-R criteria with lifetime alcohol abuse or dependence (n=34 and in a group without lifetime substance abuse or dependence (n=66. The patients were assessed using the Composite International Diagnostic Interview (CIDI for DSM-III-R disorders, the Positive and Negative Syndrome Scale, the Barratt Impulsivity Scale (BIS, the Zuckerman Seeking Sensation Scale (SSS, and the Physical Anhedonia Scale (PAS. Results: The mean scores for impulsivity and sensation seeking were higher in the group with lifetime alcohol abuse or dependence than in the group without substance abuse or dependence (BIS: 63.4 SD: 18,7 vs 51.3 SD: 14.2 respectively, ANOVA: F=11.12, p=0.001; SSS: 17.6 SD: 5.9 vs 13.5 SD: 6.7 respectively, ANOVA: F=7.45, p=0.008. There was no significant differences between the two groups on PAS score. Conclusion: Increased impulsivity or sensation seeking may be a link between schizophrenia and alcohol abuse or dependence.

    Leclère, Franck Marie P; Kolb, Frédéric; Lewbart, Gregory A; Casoli, Vincent; Vögelin, Esther

    2014-01-01

    INTRODUCTION: Depuis les premiers travaux de Jacobson et Suarez, la microchirurgie a considérablement évolué et celle-ci est devenue omniprésente en chirurgie plastique comme dans les autres spécialités chirurgicales. L’apprentissage au laboratoire des techniques de base est nécessaire avant d’envisager l’exécution de procédures cliniques. Dans cet article, nous avons évalué un modèle animal permettant de fournir une solution aux problèmes suivants : règles d’éthique, coût, anesthésie, temps nécessaire à la formation. MATÉRIEL ET MÉTHODE: Entre juillet et septembre 2012, 150 simulations de microanastomoses de vaisseaux incongruents par la technique d’Harashina ont été réalisées sur 182 Lumbricus terrestris. L’entrainement a été divisé en 10 périodes de 7 jours comprenant chacune 15 simulations de microanastomoses de vaisseaux incongruents, dont le plus petit diamètre était supérieur à 1,5 mm (n = 5), compris entre 1,0 mm et 1,5 mm (n = 5), ou inférieur à 1,0 mm (n = 5). Un modèle linéaire avec le numéro de la période comme variable principale et la taille de l’animal comme facteur étaient utilisés afin de déterminer la tendance de la durée d’exécution de l’exercice microchirurgical ainsi que les différences entre les sous-groupes de tailles différentes au cours des périodes d’apprentissages. RÉSULTATS: Le modèle linéaire montre une tendance significative (P < 0,001) à la réduction du temps opératoire durant le décours du training ainsi qu’une différence significative entre les groupes d’animaux de tailles différentes. Pour les microanastomoses de taille supérieure à 1,5 mm, le temps d’anastomose moyen est passé de 19,6±1,9 min à 12,6±0,7 min entre la première et la dernière semaine de formation (diminution de 35,7 %). Pour un training avec des vaisseaux de diamètre inférieur, les résultats montraient une diminution dans le temps d’exécution de 36,1 % (diamètre compris
