This study examines whether casual work can shorten the time taken to move from unemployment into permanent work using longitudinal data from the Survey of Employment and Unemployment Patterns. The analysis is based on comparison of the transition rate from unemployment to permanent work with the combined transition rates of unemployment to casual work and casual work to permanent work. Hazard ...

background: previous studies have confirm the effects of water extract of crocus sativus on the euphoric and behavioral properties of morphine in mice. objective: in the present study, the effects of intra-accumbal administration of alcohol extract of crocus sativus stigma on the acquisition and expression of morphine-induced conditioned place preference (cpp) in male wistar rats (250-300 g) we...

Cows will typically experience a 30 to 35% reduction in feed intake during the final two to three weeks prior to calving. Blood fatty acids at calving are negatively related to feed intake and positively related to incidence of postpartum metabolic disorders. Feed and manage cows to maximize feed intake during the transition period. Over conditioned cows are likely to have poor appetites, but d...

Consider the one-dimensional contact process. About ten years ago, N. Konno stated the conjecture that, for all positive integers n, m, the upper invariant measure has the following property: Conditioned on the event that O is infected, the events {All sites −n, . . . ,−1 are healthy} and {All sites 1, . . . , m are healthy} are negatively correlated. We prove (a stronger version of) this conje...

Endogenous opiate peptides can regulate neuroendocrine and circulatory responses to behavioral stress and may be important in the pathogenic effects of sympathoadrenal reactivity. We tested this hypothesis by examining the effect of the opiate antagonist naloxone on blood pressure responses to behavioral stress in young adults with high, medium, or low casual blood pressures. Naloxone increased...

This paper describes an acoustic-phonetic comparison of casual and clear speech styles elicited in read and spontaneous speech. For the spontaneous speech, 20 pairs of English talkers were recorded doing a problem-solving picture task in good and degraded listening conditions. Each person also read sentences in casual and clear styles. The read clear speech was an exaggerated form of clear spee...

Ubiquitous computing spaces, which have displays generously embedded into the environment, allow interaction with graphical user interfaces in a much more casual manner than desktop computers, which tie the user a particular desk. But simply putting desktop applications on a ubiquitous display will not make their use casual. We propose applications that can roam among displays as well as to per...

CONTEXT Since the advent of highly active antiretroviral therapy (HAART) in 1996, the incidence of HIV-especially among young men who have sex with men-and the prevalence of unprotected sex among HIV-positive persons have increased. The characteristics associated with unprotected sex among youth living with HIV since the advent of HAART have not been explored. METHODS Samples of HIV-positive ...

BACKGROUND The objective of the study was to explore the reach of an ongoing hepatitis B vaccination programme in terms of awareness of the programme among drug users (DUs), vaccination uptake and compliance, as well as to investigate reasons for non-participation. METHODS Ethnographic mapping and targeted sampling were used to recruit 309 DUs in three regions in the Netherlands. Results were...

Typically, in digital entertainment, the screen is the center of the player's attention. If the real world was part of the gameplay, the player would also pay attention to what is happening around her. That is the case of pervasive games. Our objective is to find ways of making pervasive play available for a large casual audience, but in a way that casual games are not deprived of their intrins...
