L'Impacte dels diaris gratuïts sobre els diaris de pagament

Com a manera d’analitzar l’efecte de les innovacions que contínuamentexperimenta el món actual, hem cregut interessant analitzar l’impacte deldiaris gratuïts o premsa gratuïta sobre els diaris de pagament o premsatradicional, ja que creiem que, tot i que tan sols representa un petit canvien un àmbit molt concret com és el de la premsa, pot significar un mirall enel que fixar-se per altres sectors d’àmbit tradicionalment privat.Avui dia, des de fa ja uns anys, quan agafes el metro o l’autobús cada matíper anar al treball o a la universitat veiem que gairebé tothom té und’aquests diaris gratuïts a la mà (Qué!, Metro, 20 Minutos, ADN...) que elshi acaben de donar a l’entrada de l’estació. Veient això s’ens van plantejaruna sèrie de preguntes: la gent que llegeix diaris gratuïts, llegeix també lapremsa tradicional? L’aparició dels diaris gratuïts, ha fet reduir el nombre delectors de premsa de pagament? El que volem esbrinar és si aquests noustipus de diaris són una amenaça o més aviat són complementaris als diarisde pagament. La pregunta que volem respondre és: Quin ha estat l’impactedels diaris gratuïts sobre els diaris de pagament.Al llarg del treball veurem que l’entrada al mercat d’aquest nou tipus depremsa no ha suposat una amenaça pels diaris tradicionals, com potsemblar en un principi. Podrem comprovar que pel que fa al nombre delectors l’impacte és gairebé nul, és a dir, és veritat que els diaris depagament han patit un estancament en quant a nombre de lectors però noha afectat quasi bé gens als beneficis d’aquests. Tambè veurem, que és enel terreny de la publicitat on realment competeixen els dos tipus de diarisaixí com tambè, que la situació és diferent al nostre entorn respecte a laresta del món.

International nursing : cultivating a culture of empowerment

International nursing has been a growing phenomenon throughout the globe. International nurses have been found to be an asset to healthcare organizations and an important part of the health care team. However, growing concern for the plight of international nurses facing obstacles such as professional stagnation and exploitation has spurred the development of strategies to mitigate and ameliorate the experiences of nurses working abroad. In this respect, the purpose of this study was to explore the management-influenced factors and the nurse team-influenced factors that promote the empowerment of the international nurse in the health care setting. The methodology used in this study was a systemic review. After a rigorous search for relevant empirical studies using OVID database, eight empirical research studies were selected using systematic review methodology to collect, analyze and synthesize data. The selected eight empirical studies were then subjected to a content analysis. The results suggested that the empowerment of an international nurse is inseparable from the empowerment of the health care organization. Based on the findings in this study, strategies to promote international nurses were found to mirror strategies evidenced to empower the nursing organization. Some of the management-influenced factors which were found to facilitate empowerment included a diversity rich work culture, transformational leadership at the management level, and a responsibility to foster the values of the organization. The team-influenced factors which were found to contribute to the empowerment of the international nurse included a united mutually-interdependent nurse team, shared accountability among the members of the nurse team, and the building of trust in work relationships. To conlude, this study indicates that efforts to empower international nurses without considering the work culture and the organization as a whole are futile because empowerment cannot take place in an environment that lacks antecedent conditions. Strategies to empower the international nurse should not focus on the deficits and special needs of the international nurse, but should focus on the similarities and commonalities of the nursing body. Empowerment of the international nurse mean open honest communication, supportive work environment, and a firm policy to quell disruptive elements that threaten the organization's values, mission, and philosophy of care.

Coordination et décentralisation des règles budgétaires dans une structure fédéraliste : le cas des cantons suisses

La coordination des politiques budgétaires entre collectivités publiques se heurte à leur souveraineté individuelle. Les règles budgétaires indépendamment adoptées peuvent potentiellement aller à l'encontre des besoins généraux de stabilisation macroéconomique. En utilisant l'exemple des cantons suisses, cette contribution analyse la possibilité de dégager une politique anti-cyclique lorsque les collectivités locales se dotent de règles les contraignant à un équilibre budgétaire ou à un quasi-équilibre. On montre que, dotées ou non de règles, les collectivités adoptent généralement un comportement pro-cyclique. Toutefois, ce comportement peut être contrecarré si le gouvernement central instrumentalise la péréquation financière verticale au profit de la stabilisation.

Government Spending and Re-election

Does additional government spending improve the electoral chances of incumbent political parties? This paper provides the first quasi-experimental evidence on this question. Our research design exploits discontinuities in federal funding to local governments in Brazil around several population cutoffs over the period 1982-1985. We find that extra fiscal transfers resulted in a 20% increase in local government spending per capita, and an increase of about 10 percentage points in the re-election probability of local incumbent parties. We also find positive effects of the government spending on education outcomes and earnings, which we interpret as indirect evidence of public service improvements. Together, our results provide evidence that electoral rewards encourage incumbents to spend part of additional revenues on public services valued by voters, a finding in line with agency models of electoral accountability.

Human milk for neonatal pain relief during ophthalmoscopy

Ophthalmoscopy performed for the early diagnosis of retinopathy of prematurity (ROP) is painful for preterm infants, thus necessitating interventions for minimizing pain. The present study aimed to establish the effectiveness of human milk, compared with sucrose, for pain relief in premature infants subjected to ophthalmoscopy for the early diagnosis of ROP. This investigation was a pilot, quasi-experimental study conducted with 14 premature infants admitted to the neonatal intensive care unit (NICU) of a university hospital. Comparison between the groups did not yield a statistically significant difference relative to the crying time, salivary cortisol, or heart rate (HR). Human milk appears to be as effective as sucrose in relieving acute pain associated with ophthalmoscopy. The study’s limitations included its small sample size and lack of randomization. Experimental investigations with greater sample power should be performed to reinforce the evidence found in the present study.

Knowledge and attitudes of nurses towards alcohol and related problems: the impact of an educational intervention

An exploratory study of quasi-experimental approach that aimed to verify the impact of an educational intervention on attitudes and knowledge of nurses towards alcohol use and associated problems. The sample included 185 nurses, divided into two groups: 84 submitted to a training course and formed the experimental group. Data were collected through a knowledge survey and an attitude scale. The attitudes of the participants of both groups were positive. There were no significant differences between groups in relation to knowledge. The strongest predictors of positive attitudes were possessed preparation to act with chemical dependents (OR = 2.18), "have received increased workload during graduation on the theme, 'alcohol and other drugs'" (OR = 1.70), and "completed graduate school" (OR = 2.59). The educational intervention had a positive impact on the attitudes of nurses towards alcoholics, work and interpersonal relationships with such clientele.

Effectiveness of prayer in reducing anxiety in cancer patients

Objective: To evaluate the effect of prayer on anxiety in cancer patients undergoing chemotherapy. Method: Quasi-experimental study, with pre and post-intervention. Twenty patients admitted to treatment of continuous intravenous chemotherapy were recruited. The volunteers were evaluated through interviews using a questionnaire of sociodemographic, clinical and spiritual characteristics, the Index of Religiosity Duke University and the State-Trait Anxiety Inventory. Vital signs were measured and collected salivary cortisol. The intervention was applied prayer and data collection occurred in three phases: first collection (baseline), pre and post-intervention. Results: The data found between the pre and post-intervention samples showed different statistically significant for state anxiety (p= <0.00), blood pressure (systolic, p=0.00, diastolic, p=<0.00) and respiratory rate (p=0.04). Conclusion: Prayer, therefore, proved to be an effective strategy in reducing the anxiety of the patient undergoing chemotherapy.




The influence of institutionalization on the perception of autonomy and quality of life in old people

Objective To evaluate the influence exercised by institutionalization on the autonomy and perception of quality of life among the institutionalized elderly. Method The study is quasi-experimental (interrupted time series) and longitudinal. The sample is composed for 104 elderly people who went into a three nursing home in Santander, Spain. To assess the quality of life and dependence two scales were used: the Barthel Index and Lawton Index. Results There was an important relationship between autonomy and independence and their deterioration due to their institutionalisation, such as the physical and social aspects. Conclusion It´s important to point out that the dependence of the elderly is a complex phenomenon, which admits many types of intervention, including the customary ones referring to more classic welfare actions which tend to supplant the absence of autonomy in everyday life by facilitating services and attention to make up for this need, without having to resort to institutionalization.

Educational intervention on malignant hyperthermia with nursing professionals of the operating room

OBJECTIVE To evaluate the effectiveness of an educational intervention on malignant hyperthermia with operating room nurses. METHOD A quasi-experimental study, aimed at an educational intervention of short duration with the nursing staff in the operating room of the institution hosting the research in the city of São Paulo, with the participation of 96 professionals. Pre-intervention tests and post-intervention tests were applied, which consisted of a lecture followed by simulation. RESULTS Considering the overall results of the intervention, there was a statistically significant difference (p<0.00). After the educational intervention, there was an increase of the minimum and maximum scores, and average growth of 2.64 points in the knowledge of professionals when compared to the previous step. CONCLUSION The educational intervention strategy favors the concept of the content developed by everyone involved and qualifies professionals to work safely.

Effectiveness Of 2% And 4% Papain Gels In The Healing Of Venous Ulcers

OBJECTIVE To analyze the effectiveness of 2% and 4% papain gels in tissue repair of venous ulcers. METHOD Quasi-experimental study with consecutive sample of 16 patients with 30 venous ulcers treated at the outpatient clinic of a teaching hospital, from April to November in 2011, using a form for clinical assessment of the patient and its lesion. Variables were analyzed by Wilcoxon and McNemar test (p < 0.05). RESULTS Most participants were female; aged between 51 and 59 years; obese; with hypertension. Regarding ulcers, there was an average decrease of 7.9 cm2 (50% of its original size) in 90 days; 20% of the ulcers completely healed within 56.67 days. There was an increase in epithelialization, significant reduction in the slough and edema, improved depth, in the type and amount of exudate (p < 0.0001). CONCLUSION 2% and 4% papain gels were effective in healing venous ulcers.

What do outside experts bring to a committee? Evidence from the Bank of England

We test whether outside experts have information not available to insiders by usingthe voting record of the Bank of England's Monetary Policy Committee. Memberswith more private information should vote more often against conventional wisdom,which we measure as the average belief of market economists about future interest rates. We find evidence that external members indeed have information notavailable to internals, but also use a quasi-natural experiment to show they mayexaggerate their expertise to obtain reappointment. This implies that an optimalcommittee, even outside monetary policy, should potentially include outsiders, butneeds to manage career concerns.

Price increase and stability with new entries in Cournot markets

It is widely accepted in the literature about the classicalCournot oligopoly model that the loss of quasi competitiveness is linked,in the long run as new firms enter the market, to instability of the equilibrium. In this paper, though, we present a model in which a stableunique symmetric equilibrium is reached for any number of oligopolistsas industry price increases with each new entry. Consequently, the suspicion that non quasi competitiveness implies, in the long run, instabilityis proved false.

The impact of interest-rate subsidies on long-term household debt: Evidence from a large program

The responsiveness of long-term household debt to the interest rate is acrucial parameter for assessing the effectiveness of public policies aimedat promoting specific types of saving. This paper estimates the effect ofa reform of Credito Bonificado, a large program in Portugal that subsidizedmortgage interest rates, on long-term household debt. The reform establisheda ceiling in the price of the house that could be financed through theprogram, and provides plausibly exogenous variation in incentives. Usinga unique dataset of matched household survey data and administrative recordsof debt, we document a large decrease in the probability of signing a newloan after the removal of the subsidy.

The role of institutions in the contractual process

Human beings increase their productivity by specializingtheir resources and exchanging their products. Theorganization of exchange is costly, however, becausespecialized activities need coordination and incentiveshave to be aligned. This work first describes how theseexchanges are organized in an institutional environment.It then focuses on the dual effect of this environment-as with any other specialized resource, institutions maybe used for expropriation purposes. They enjoyspecialization advantages in safeguarding exchange butthey also make possible new forms of opportunism,causing new costs of exchange. Three perverse tendenciesare identified:In the legal field, there is a surplus ofmandatory rules and, at the same time, a deficit in default rules. Second, courts activity is biased againstthe quasi-judicial role of the parties and the market. Third, Market enforcement is based on reputationalassets that are badly exposed to opportunism.
