    2015-01-01

    Patron-Driven Acquisitions (PDA) is a new model used for e-book acquisition by academic libraries. A key component of this model is to make records of ebooks available in a library catalog and let actual patron usage decide whether or not an item is purchased. However, there has been a lack of research examining the role of the library catalog as…

    To assess the effect of an antismoking advertisement under real-world conditions. Design Quasi-experimental study. Multiplex cinema in Kiel, Germany; 4073 patrons were surveyed after having viewed a movie. Some 4005 patrons were > or = 10 years old (28.7% between 10 and 17 years). A total of 654 subjects (16.3%) were smokers. In the intervention condition (weeks 1 and 3), a 30-second antismoking advertisement-accentuating long-term health consequences of smoking and promoting cessation-was shown prior to all movies; in the control condition (weeks 2 and 4) no such spot was shown. (i) Awareness of smoking in the movie, (ii) approval of smoking in the movie, (iii) attitude towards smoking, (iv) intention to smoke in the future and (v) desire to smoke among smokers. Findings Patrons who were exposed to the antismoking advertisement were more likely to be female, but did not differ with respect to smoking status. After controlling for gender differences, patrons exposed to the antismoking advertisement had (i) higher awareness of smoking in the movies, (ii) lower levels of approval of smoking in the movies, and (iii) a more negative attitude towards smoking in general compared with those not exposed. Among smokers, smoking in the movies increased urge to smoke, but there was no interaction between smoking in the movies and experimental condition. Study results suggest that placing an antismoking advertisement before movies can affect attitudes towards smoking, bolstering evidence in support of such policies.

    Full Text Available OBJECTIVE: The study aims to evaluate the predictors of non-prescription medicine purchasing patterns among pharmacy patrons in Malaysia. METHODS: A cross-sectional nationwide study was undertaken in 2011 in sixty randomly selected community pharmacies across 14 Malaysian states. A pharmacy exit survey was conducted over a 6-month period across Malaysia. A one-stage random cluster sampling technique was employed as there was no national sampling framework available for conducting this survey. Face-to-face interviews using a validated and pre-tested questionnaire were conducted by trained data collectors. The non-prescription medicine purchasing pattern was explored and analysed descriptively. Chi-square/Fisher exact test was used to determine the association between study variables. Multinomial logistic regression analysis was used to determine the predictors of type of non-prescription medicine purchased. RESULTS: A total of 2729 pharmacy patrons agreed to participate in 60 selected pharmacy outlets. A total of 3462 non-prescription medicine were purchased during the study period with an average of 1.3 medicines per participant. Most of the non-prescription medicine purchased was meant for alimentary tract and metabolism (31.8%, followed by respiratory system (19.4% and musculoskeletal system (15.8% usage. Factors found to be associated with the choice of non-prescription medicine purchased were age group [χ2 = 170.75, (df = 57, p<0.01], locality [χ2 = 48.16, (df = 19, p<0.01], gender [χ2 = 32.93, (df = 13, p = 0.002], ethnic group [χ2 = 118.89, (df = 39, p<0.01] and type of occupation [χ2 = 222.434, (df = 117, p<0.01]. Non-prescription medicine purchased defined about 20% of the variance in the combination of predictors such as locality, gender, age, ethnicity, type of occupation and household income. CONCLUSION: The predictors for selection of non-prescription medicine were locality (urban or rural, gender, age, ethnicity, type of

    The purpose of the present study was to investigate the potential associations of binge drinking detected at the exit of nightclubs and risk behaviors and alcohol effects just after leaving the venue in a representative sample of Brazilian nightclub patrons according to sex. For this purpose, a portal survey study called Balada com Ciência was conducted in 2013 in the megacity of São Paulo, Brazil, using a two-stage cluster sampling survey design. Individual-level data were collected in 2422 subjects at the entrance and 1822 subjects at the exit of 31 nightclubs, and breath alcohol concentration (BrAC) was measured using a breathalyzer. The following day, 1222 patrons answered an online follow-up survey that included questions about risk behaviors and alcohol effects practiced just after leaving the nightclub. Weighted logistic regressions were used to analyze binge drinking associated with risk behaviors by sex. For both sexes, the most prevalent risk behaviors practiced after leaving a nightclub were drinking and driving (men=27.9%; women=20.4%), the use of illicit drugs (men=15.8%; women=9.4%) and risky sexual behavior (men=11.4%; women=6.8%). The practice of binge drinking increased the behavior of illicit drug use after leaving the nightclub by 2.54 times [95% CI: 1.26-5.09] among men who drank and increased the risk of an episode of new alcohol use by 5.80 times [95% CI: 1.50-22.44] among women who drank. Alcoholic blackouts were more prevalent among men [OR=8.92; 95% CI: 3.83-20.80] and women [OR= 5.31; 95% CI: 1.68-16.84] whose BrAC was equivalent to binge drinking compared with patrons with a lower BrAC. Public policies aiming to reduce patrons' BrAC at the exit of nightclubs, such as staff training in responsible beverage service and legislation to prevent alcohol sales to drunk individuals, would be useful to protect patrons from the risk behaviors associated with binge drinking in nightclubs.

    1993-01-01

    To examine the extent to which hotel patrons drink in excess of current health recommendations, and to identify risk factors for excessive drinking, hotel patrons were invited to participate in a survey of social drinking, which included a free breath test. Patrons were approached at 15 min. intervals, and 1000 subjects were studied. Amongst this group of hotel patrons interviewed, 1 in 2 had consumed alcohol in excess of the daily limit recommended by the National Health & Medical Research Council. One in 10 intending drivers had a BAC over the legal limit. Excessive drinking and drink driving appear to be prevalent amongst hotel patrons, and hotels should be targets for interventions designed to reduce these problems. For example, the National Guidelines for the Responsible Serving of Alcohol should be more widely practised.

    René Goupil, the Patron Saint of Anaesthetists, and a Patron Saint of Canada, was born in Angers, France in 1608 and studied surgery. He joined the Jesuits as a donné or volunteer worker in 1640 and served in the then tiny colony of Quebec as one of the first medical workers of Canada. After earning meritorious praise for his skills, he again volunteered to attend the Hurons at Sainte Marie, a mission far beyond the frontiers. René's canoe party was ambushed. He was captured by the Mohawks and endured eight weeks of cruel torture before being killed on September 29, 1642. René was the first of eight North American martyrs whose dedication was recognized by canonization in 1930. St. René was appointed Patron Saint of Anaesthetists in 1951.

    We evaluated the impact on alcohol intake and blood alcohol concentration (BAC) of a multi-level structural intervention to increase the availability of free water, coupled with messaging on pacing alcohol intake and normative feedback of blood alcohol concentration in a convenience sample of gay bars in San Francisco. Participants (n = 1,293) were recruited among exiting patrons of four gay bars (two intervention bars and two control bars). Participants were surveyed on alcohol intake and BAC was measured by breathalyzer. Prior to the intervention there were no significant differences in baseline alcohol measures between intervention and control bars. Post-intervention there were significant differences on objective and subjective measures of alcohol consumption: 30% of intervention bar participants had BAC% levels over the legal driving limit (0.08%) compared to 43% of control bar participants, p < 0.0001 and 78% of intervention bar participants were above the AUDIT-C cut-off for hazardous drinking compared to 87% in control bars, p < 0.001.

    Alcohol-related harm in and around licensed venues is associated with substantial costs. Many interventions have been introduced in an effort to combat these harms, and one such intervention is known as patron banning. Patron banning involves prohibiting patrons who have been violent or disorderly in a licensed venue in an attempt to reduce alcohol-related harm. It can be implemented by the venue, by members of police, or by liquor accords. This study aimed to obtain key informant perspectives on the benefits of patron banning as well as on the effectiveness of patron banning in reducing alcohol-related harm. Thirty-six key informants provided perspectives on patron banning through in-depth interviews that were part of a larger study. Key informants were supportive of patron banning for reducing alcohol-related harm, noting that it had many benefits including increased venue safety, general risk management, and deterrence of antisocial behavior. Although processes for banning were not always consistent, identification scanners were generally recognized as a way to ensure that patron banning was enforced. Key informants viewed patron banning as an effective measure for increasing patron safety and reducing alcohol-related harms.

    Restaurant initiatives provide an efficient opportunity to impact large numbers of patrons. The purpose of this study is to measure patron purchasing behaviors during the ¡Por Vida! menu designation initiative. This study used a cross-sectional design and survey data to assess 23 restaurants throughout Bexar County and 152 restaurant patrons. The Patron Awareness Questionnaire assessed if patrons noticed the logo; believed nutrition, cost, and taste were important in making purchasing decisions; and purchased a ¡Por Vida! item. Descriptive statistics, Spearman correlations, and logistic regression were used to analyze the data. Most (93.4%) patrons considered taste very important when deciding what to eat. Cost was very important to 63.8% and nutrition was very important to 55.9% of the sample. The strongest predictors of purchasing a ¡Por Vida! item were the patrons' ages being between 18 and 35 years (odds ratio = 1.474; confidence interval = 0.017, 0.812; p designation initiatives can potentially influence patron purchasing behaviors among a segment of the population when the logo is visible.

    Full Text Available Patrons of public libraries are more diverse and complex than those of other types of libraries, implying potentially more unexpected and difficult situations. Negative emotions such as frustration and anxiety are generated among librarians when they must handle problem patrons, an effort that may influence the work efficiency of librarians and their physical and mental health. This study conducted a semi-structured in-depth interview, using public service librarians in Taiwan as subjects, to explore the categories of problem patrons and their behavioral characteristics. According to the results, the behavioral characteristics of problem patrons can be divided into 6 categories: interfering with others, violating library regulations, influencing library works, improperly using resources and facilities, breaking laws, and exhibiting a psychological disorder as well as violating social norms. On the basis of the research results, this study offers suggestions for future reference when public libraries must handle problem patrons.

    1990-01-01

    This study examined changes in sales of low fat/low cholesterol foods targeted in a restaurant menu labeling program. Sales of labeled items were tracked before and after the program was introduced, and a subsample of patrons were surveyed for information on visibility and comprehension of the menu labels. Two of the four restaurants had significant increases in the sales of targeted foods following labeling. Comparisons between patrons dining in restaurants which had an increase in sales (I--increase restaurants) to those dining in restaurants which had no overall shift in sales (NI--no increase restaurants) revealed no differences in patron awareness or comprehension of the menu labels. There were age and gender differences between I and NI restaurants, with I restaurants having proportionally more males, and a younger clientele. Taste was the primary reason given by patrons for their entree choice, regardless of whether or not it was labeled. In all four restaurants women and older patrons were more aware of the program and more responsive to its recommendations. These findings suggest that environmental strategies may be an effective method of encouraging dietary changes in the general population, but patron characteristics such as age and gender may influence receptivity to this type of intervention. Future studies aimed at developing effective point of purchase education programs should evaluate these patron characteristics and include more powerful behavior change strategies.

    Electronic music and dance events in nightclubs attract patrons with heavy alcohol/drug use. Public health concerns are raised from risks related to these behaviors. Practices associated with increased risk in these club settings need to be identified. The relationship between club management practices and biological measures of patrons' alcohol/drug use is examined. Observational data from 25 events across six urban clubs were integrated with survey data (N = 738 patrons, 42.8% female) from patrons exiting these events, 2010-2012. Five indicators of club management practices were examined using mixed model regressions: club security, bar crowding, safety signs, serving intoxicated patrons, and isolation. Analyses revealed that serving intoxicated patrons and safety signs were related to substance use. Specifically, serving intoxicated patrons was related to heavy alcohol and drug use at exit, while safety signs were marginally related to less exit drug use. CONCLUSIONS/IMPORTANCE: Findings indicate observable measures in nightclubs provide important indicators for alcohol/drug use, suggesting practices to target. Study strengths include the use of biological measures of substance use on a relatively large scale. Limitations and future directions are discussed.

    Determine the relationship of subjective intoxication to blood alcohol concentration (BAC) and examine whether patron and event-level characteristics modify the relationship of BAC to subjective intoxication. An in-situ systematic random sample of alcohol consumers attending night-time entertainment districts between 10pm and 3am on Friday and Saturday nights in five Australian cities completed a brief interview (n=4628). Participants reported age, sex, and pre-drinking, energy drink, tobacco, illicit stimulant and other illicit drug use that night, and their subjective intoxication and BAC were assessed. Male and female drinkers displayed equally low sensitivity to the impact of alcohol consumption when self-assessing their intoxication (BAC only explained 19% of variance). The marginal effect of BAC was not constant. At low BAC, participants were somewhat sensitive to increases in alcohol consumption, but at higher BAC levels that modest sensitivity dissipated (actual BAC had less impact on self-assessed intoxication). The slope ultimately leveled out to be non-responsive to additional alcohol intake. Staying out late, pre-drinking, and being young introduced biases resulting in higher self-assessed intoxication regardless of actual BAC. Further, both energy drinks and stimulant use modified the association between BAC and perceived intoxication, resulting in more compressed changes in self-assessment as BAC varies up or down, indicating less ability to perceive differences in BAC level. The ability of intoxicated patrons to detect further intoxication is impaired. Co-consumption of energy drinks and/or stimulant drugs is associated with impaired intoxication judgment, creating an additional challenge for the responsible service and consumption of alcohol.

También se señalan aciertos, en la medición de las calificaciones por el grado de dominio en la comprensión de la tarea realizada. Pero se destaca la problemática relación de los pronósticos de descalificación absoluta con el concepto de miseria creciente. Se subrayan las implicancias políticas de esta tesis. El artículo pondera del enfoque totalizador de Braverman y su énfasis en la centralidad y no el fin del trabajo. Destaca como su mirada permite comprender el trasfondo confiscatorio de la precarización actual del empleo.

    A growing literature is addressing the nature of the relationships among gambling activity, gambling involvement, and gambling-related problems. This research suggests that among the general population, compared to playing any specific game, gambling involvement is a better predictor of gambling-related problems. To date, researchers have not examined these relationships among casino patrons, a population that differs from the general population in a variety of important ways. A survey of 1160 casino patrons at two Las Vegas resort casinos allowed us to determine relationships between the games that patrons played during the 12 months before their casino visit, the games that patrons played during their casino visit, and patrons' self-perceived history of gambling-related problems. Results indicate that playing specific gambling games onsite predicted (i.e., statistically significant odds ratios ranging from .5 to 4.51) self-perceived gambling-related problems. However, after controlling for involvement, operationally defined as the number of games played during the current casino visit and self-reported gambling frequency during the past 12 months, the relationships between games and gambling-related problems disappeared or were attenuated (i.e., odds ratios no longer statistically significant). These results extend the burgeoning literature related to gambling involvement and its relationship to gambling-related problems.

    To examine the event-specific relationship between alcohol intoxication and nighttime tobacco smoking among college bar patrons. In this secondary analysis of existing data, we examined event-specific associations between self-report measures of tobacco smoking and breath alcohol concentration (BrAC) readings obtained from 424 patrons exiting on-premise drinking establishments. In a multivariable logistic regression analysis, acute alcohol intoxication was positively associated with same-night incidents of smoking tobacco, adjusting for the effects of established smoking practices and other potential confounders. This investigation is the first known study using data collected in an on-premise drinking setting to link alcohol intoxication to specific incidents of tobacco smoking.

    Previous laboratory research on alcohol absorption has found that substitution of artificially sweetened alcohol mixers for sucrose-based mixers has a marked effect on the rate of gastric emptying, resulting in elevated blood alcohol concentrations. Studies conducted in natural drinking settings, such as bars, have indicated that caffeine ingestion while drinking is associated with higher levels of intoxication. To our knowledge, research has not examined the effects of alcohol mixers that contain both an artificial sweetener and caffeine, that is, diet cola. Therefore, we assessed the event-specific association between diet cola consumption and alcohol intoxication in bar patrons. We sought to determine whether putative increases in blood alcohol, produced by accelerated gastric emptying following diet cola consumption, as identified in the laboratory, also appear in a natural setting associated with impaired driving. We conducted a secondary analysis of data from 2 nighttime field studies that collected anonymous information from 413 randomly selected bar patrons in 2008 and 2010. Data sets were merged and recoded to distinguish between energy drink, regular cola, diet cola, and noncaffeinated alcohol mixers. Caffeinated alcohol mixers were consumed by 33.9% of the patrons. Cola-caffeinated mixed drinks were much more popular than those mixed with energy drinks. A large majority of regular cola-caffeinated mixed drink consumers were men (75%), whereas diet cola-caffeinated mixed drink consumers were more likely to be women (57%). After adjusting for the number of drinks consumed and other potential confounders, number of diet cola mixed drinks had a significant association with patron intoxication (β = 0.233, p 0.05). Caffeine's effect on intoxication may be most pronounced when mixers are artificially sweetened, that is, lack sucrose which slows the rate of gastric emptying of alcohol. Risks associated with on-premise drinking may be reduced by greater

    Relatively few studies have examined gambling problems among individuals in a casino setting. The current study sought to examine the prevalence of gambling problems among a sample of casino patrons and examine alcohol and tobacco use, health status, and quality of life by gambling problem status. To these ends, 176 casino patrons were recruited by going to a Southern California casino and requesting that they complete an anonymous survey. Results indicated the following lifetime rates for at-risk, problem, and pathological gambling: 29.2, 10.7, and 29.8%. Differences were found with regards to gambling behavior, and results indicated higher rates of smoking among individuals with gambling problems, but not higher rates of alcohol use. Self-rated quality of life was lower among pathological gamblers relative to non-problem gamblers, but did not differ from at-risk or problem gamblers. Although subject to some limitations, our data support the notion of higher frequency of gambling problems among casino patrons and may suggest the need for increased interventions for gambling problems on-site at casinos.

    To assess preferences of grocery store patrons concerning pharmacy services and identify study participant characteristics that may predict the success of pharmacy services in the community setting. Self-administered survey. Central Ohio from December 16, 2005, to January 12, 2006. 163 grocery store patrons. Eight grocery store survey events. Responses to survey items about (1) perceived importance of 28 pharmacy services, (2) identification of the 3 most important services, (3) frequency of grocery store and pharmacy use, (4) preferred methods of advertising pharmacy services, and (5) socioeconomic demographics. Preferred services delineated by various demographics also were analyzed. A total of 163 surveys were returned from study participants. Nine services appeared in both the top 12 overall preferred services and the 12 highest-ranked services. Statistically significant differences were observed among services ranked as important or very important by age, race, employment, income, caregiver status, and prescription drug coverage status. The three advertising tools selected most frequently included: weekly grocery store ads (68.6%), in-store signs (51.0%), and flyers attached to prescription bags (36.0%). Grocery store patrons would like a wide range of nontraditional pharmacy services that could be implemented into community pharmacies. Pharmacies in grocery stores need to provide both traditional and expanded pharmacy services to meet the desires and expectations of current and potential patients, and expanded marketing methods should be considered.

    Full Text Available Los patrones de asentamiento son las pautas con las que distribuyen los diferentes elementos construidos, como casas, caminos, campos, espacios públicos o fábricas, y son una expresión cultural de la sociedad que los construye. Tanto el tipo de elementos, su número como su distribución, dependen del nivel tecnológico, de la estructura social y de su bagaje cultural. Se puede decir, por tanto, que en los patrones estaría reflejado el conocimiento que la sociedad tenia del medio, así como sus anhelos, prioridades e, incluso, sus malas prácticas. La presente comunicación propone que estos patrones puedan servir de base para el planeamiento territorial actual, no sólo preservando aquello que realmente tenga valor, sino incluso recreándolos o reproduciéndolos a otras escalas siempre que puedan aportar un valor añadido al territorio. El escrito plantea una pregunta: ¿Qué se debe mantener de los patrones tradicionales y qué se puede, o incluso se debe, cambiar?, y para responderla en la primera parte se analizan someramente algunos asentamientos-tipo y en la segunda se indican pautas de actuación que han aparecido como propuestas en planes de ordenación territorial en los últimos años.

    Drinking before entering nightclubs (predrinking) seems to be associated with an increase in alcohol-related harm. This study aims to investigate gender differences in predrinking behavior and to evaluate its association with risk behaviors practiced inside nightclubs. Individual-level data were collected by a portal survey of 2,422 patrons at the entrance and 1,833 patrons at the exit of 31 nightclubs located at São Paulo, Brazil. The nightclubs were selected by 2-stage sampling with probability proportional to the establishments' capacity in the first stage and a systematic sample of patrons in the entrance line in the second stage. Breath alcohol concentration (BrAC) was measured at the entrance and exit. Face-to-face interviews identified predrinking characteristics and risk behaviors. Weighted analyses were stratified by gender. Predrinking was practiced by 49.2% (95% confidence interval [CI] = 42.7 to 55.8) of the male patrons and 29.0% (95% CI = 20.6 to 38.9) of the female patrons (p men and women showed similar BrAC at entrance and exit and similar proportion of alcoholic intoxication (BrAC ≥ 0.38 mg/l). In both genders, people who practiced predrinking on the day of the interview were more likely to drink inside the nightclub, compared to those who did not practice predrinking (p men, the practice of predrinking increased the chance of "drinking and driving" after leaving the nightclub (odds ratio [OR] = 6.9, 95% CI = 4.1-11.5, p sexual harassment in the nightclub (OR = 2.9, 95% CI = 1.3 to 6.6, p = 0.010). Predrinking is more prevalent among men; however, men and women who engaged in predrinking have a similar pattern of alcohol consumption and exit BrAC. The fact that risk behaviors and illicit drug use were associated with predrinking but differ between genders suggests that a gender-specific approach should be used in tailored interventions to prevent alcohol-related harm in nightclubs.

    Alcohol sales to intoxicated patrons are illegal and may lead to public health issues such as traffic crashes and violence. Over the past several decades, considerable effort has been made to reduce alcohol sales to underage persons but less attention has been given to the issue of sales to obviously intoxicated patrons. Studies have found a high likelihood of sales to obviously intoxicated patrons (i.e., overservice), but little is known about efforts by enforcement agencies to reduce these sales. We conducted a survey of statewide alcohol enforcement agencies and local law enforcement agencies across the US to assess their strategies for enforcing laws prohibiting alcohol sales to intoxicated patrons at licensed alcohol establishments. We randomly sampled 1,631 local agencies (1,082 participated), and surveyed all 49 statewide agencies that conduct alcohol enforcement. Sales to obviously intoxicated patrons were reported to be somewhat or very common in their jurisdiction by 55 % of local agencies and 90 % of state agencies. Twenty percent of local and 60 % of state agencies reported conducting enforcement efforts to reduce sales to obviously intoxicated patrons in the past year. Among these agencies, fewer than half used specific enforcement strategies on at least a monthly basis to prevent overservice of alcohol. Among local agencies, enforcement efforts were more common among agencies that had a full-time officer specifically assigned to carry out alcohol enforcement efforts. Enforcement of laws prohibiting alcohol sales to obviously intoxicated patrons is an underutilized strategy to reduce alcohol-related problems, especially among local law enforcement agencies.

    Brazil has a strict drinking and driving law known as the Brazilian "Dry Law". The aim of the present study was to investigate characteristics associated with the breaking of the Brazilian traffic law, on drinking and driving, at nightclub exit among a representative sample of nightclub patrons in the city of São Paulo, Brazil. Portal survey realized with a two-stage cluster sampling survey design to collect data from 2422 patrons at the entrance and 1822 patrons at the exit of 31 nightclubs in the city of São Paulo, Brazil. Patrons' breath alcohol concentrations (BrACs) at the entrance and exit of the nightclubs were categorized according to the law as either a "traffic offense" or a "traffic offense and crime". Weighted multinomial logistic regression was used to analyze factors associated with different patterns of drinking and driving offenses. Of the subjects, 16.5% (n=369) were identified as driving patrons at the entrance and exit of the nightclubs. At entry, 80.1% of the patrons had a zero BrAC, 14.9% had a BrAC meeting the traffic offense criteria and 5.0% had a BrAC meeting the traffic offense and crime criteria. Women were less likely to have BrACs meeting the traffic offense criteria. At nightclub exit, 63.4% of patrons had maintained a zero BrAC, 24.7% had a BrAC that had increased and now met the traffic offense and crime criteria, and 11.9% had a decreased or stable BrAC. An increased BrAC was more frequently identified in patrons who were men, were single, and had used illicit drugs inside the nightclub. Despite the existence of a strict law regarding drinking and driving, a significant proportion of nightclub patrons in the city of São Paulo had violated this law, suggesting a perception of impunity and need for law enforcement.

    Objectives. We compared exposure to secondhand smoke (SHS) and attitudes toward smoke-free bar and nightclub policies among patrons of lesbian, gay, bisexual, and transgender (LGBT) and non-LGBT bars and nightclubs. Methods. We conducted randomized time–location sampling surveys of young adults (aged 21–30 years) in 7 LGBT (n = 1113 patrons) and 12 non-LGBT (n = 1068 patrons) venues in Las Vegas, Nevada, in 2011, as part of a cross-sectional study of a social branding intervention to promote a tobacco-free lifestyle and environment in bars and nightclubs. Results. Compared with non-LGBT bars and nightclubs, patrons of LGBT venues had 38% higher adjusted odds of having been exposed to SHS in a bar or nightclub in the past 7 days but were no less likely to support smoke-free policies and intended to go out at least as frequently if a smoke-free bar and nightclub law was passed. Conclusions. The policy environment in LGBT bars and nightclubs appears favorable for the enactment of smoke-free policies, which would protect patrons from SHS and promote a smoke-free social norm.

    To attract golf patrons, sport managers must understand consumption patterns of the golfer. Importantly, the treatment of travel costs must be understood. According to the Alchian-Allen (1964) theorem, golfers treat travel costs as bundled costs (third law of economic demand) whereas classical consumer theory indicates that golfers treat travel costs as sunk costs (first law of economic demand). The purpose of this study was to determine if golf patrons treated travel costs as sunk costs o...

  7. Patron-driven acquisitions history and best practices

    CERN Document Server

    2011-01-01

    About 40 percent of the books academic libraries purchase in traditional ways never circulate and another 40 percent circulate fewer than three times. By contrast, patron-driven acquisition allows a library to borrow or buy books only when a patron needs them. In a typical workflow, the library imports bibliographic records into its catalogue at no cost. When a patron finds a patron-driven record in the course of research, a short-term loan can allow him to borrow the book, and the transaction charge to the library will be a small percentage of the list price. Typically, a library will automatically buy a book on a third or fourth use. The contributions in this volume, written by experts, describe the genesis and brief history of patron-driven acquisitions, its current status, and its promise.

    Full Text Available This study explores the usability problems for the middle-aged and elderly users of the automatic ticket vending machines of Taipei Mass Rapid Transit System. Thirty two middle-aged and elderly users (16 men and 16 females were observed in their actual uses of the machines, and 9 of them (6 men and 3 women were interviewed afterwards. The results show that, first, most senior users observed in this study made mistakes at the first step of touching the screen that initiates the ticket buying process. Second, the feedback and voice guidance design need further improvement to facilitate the senior users’ operation of the machines. Based on the findings, this study recommends that: (1 the operation instruction may be improved by enhancing the color contrast and graphics complementing of caption and voice guidance; (2 the transaction interface should be simplified, avoiding using button symbol to show information, and the visual instruction should be supplemented with voice instructions; (3 operation feedback should be strengthened and in line with previous use experience.

    A field experiment was conducted in order to test the assumptions by the Supreme Court in Barnes v. Glen Theatre, Inc. (1991) and the Ninth Circuit Court of Appeals in Colacurcio v. City of Kent (1999) that government restrictions on dancer nudity and dancer-patron proximity do not affect the content of messages conveyed by erotic dancers. A field experiment was conducted in which dancer nudity (nude vs. partial clothing) and dancer-patron proximity (4 feet; 6 in.; 6 in. plus touch) were manipulated under controlled conditions in an adult night club. After male patrons viewed the dances, they completed questionnaires assessing affective states and reception of erotic, relational intimacy, and social messages. Contrary to the assumptions of the courts, the results showed that the content of messages conveyed by the dancers was significantly altered by restrictions placed on dancer nudity and dancer-patron proximity. These findings are interpreted in terms of social psychological responses to nudity and communication theories of nonverbal behavior. The legal implications of rejecting the assumptions made by the courts in light of the findings of this study are discussed. Finally, suggestions are made for future research.

    For over a decade, some academic libraries have been purchasing, rather than borrowing, recently published books requested by their patrons through interlibrary loan. These books had one circulation guaranteed and so appealed to librarians who were concerned about the large percentage of books selected and purchased by librarians but never checked out by their patrons. Early assessments of the projects indicated that patrons selected quality books that in many cases were cross disciplinary and covered emerging areas of scholarly interest.

    Full Text Available Objective – To test a metric for library use, that could be comparable to metrics used by competing government departments, for ease of understanding by policy makers. Design – Four types of data were collected and used: Time-diaries, exit surveys, gate counts, and circulation statistics. Setting – A large public library in British Columbia, Canada. Subjects – Time-diary subjects were 445 patrons checking out materials; exit survey subjects were 185 patrons leaving the library. Methods – A paper-based time diary, prototypes of which were tested, was given to patrons who checked out library materials during a one-week period. These patrons were charged with recording the use of the checked-out items during the entire three-week loan period. From this information, the average number of hours spent with various types of loaned material (print and audio/DVD was calculated. The average number of hours spent per item type was then applied to the circulation statistics for those items, across a month, to get a total of hours spent using all circulated material during that month. During the same one-week period of time-diary distribution, exit surveys were conducted by library staff with patrons leaving the library, asking them how long they had spent in the library during their current visit. The average number of minutes per visit was calculated and then applied to the gate count for the month, to get a total number of minutes/hours spent “resident” in the library that month. Adding the totals, a grand total of patron time-use hours was calculated. A monetary value was applied per hour, using the results of a contingent valuation study from Missoula, Montana (Dalenberg et al., 2004, in order to convert hours of library benefit into a dollar figure. Main Results – There was a 24% response rate for the time diaries (106/445. The diary entries yielded an average of 3.5 hours of time-use per print item, and 1.9 hours per DVD. The range for

La mayoría de los estudios anteriores se basan en la ecografía y sólo hay unos cuantos estudios basados en autopsias fetales. El Análisis detallado de los distintos parámetros puede proporcionar una base de datos útil para una rápida referencia. Métodos: En cincuenta fetos normales de edades gestacionales diferentes, se midieron los siguientes parámetros: las distancias cantales externa e interna, la longitud de la hendidura palpebral, la longitud oropalpebral, la profundidad y la anchura de la órbita y la distancia interorbital. Resultados: El análisis estadístico reveló una correlación positiva significativa de todos estos parámetros con la edad gestacional y con el diámetro biparietal. Los patrones de crecimiento de los pará-metros orbitales y orbitofacial también demostraron una correlación significativa entre sí. Conclusión: Nuestros resultados muestran que el aumento de las partes laterales de la cara y de la longitud facial vertical se produce a un ritmo más rápido en comparación con la parte media de la cara. Las desviaciones de los datos normativos generados para los parámetros orbitales y orbitofacial ayudarán en la detección precoz de síndromes genéticos específicos. Objective: Fetal orbitofacial and orbital measurements may be helpful in early prenatal diagnosis of craniofacial malformation. Most of the earlier studies are ultrasound based and there are only a few studies based on fetal autopsies. Comprehensive analysis of various parameters can provide useful database for easy reference. Methods: In fifty normal fetuses of different gestational ages, the following parameters were measured: outer and inner canthal distances, palpebral fissure length, oropalpebral length, depth and width of orbit and inter orbital distance. Results: Statistical analysis

    Full Text Available Food and alcohol are the key elements of celebrating a Mexican fiesta. I show that drinking at patronal feasts can be the way of constructing a respectful position, as presented in the ethnographic material collected in the three suburban communities of the Central Valleys of Oaxaca (in the years 2012–13. I discuss the relation between drinking alcohol at fiestas, participation and collective identity. I analyse the issue of prestige in the context drinking at fiestas and its relation to gender. I also discuss the role of alcohol in ritual exchanging of gifts at the patronal feasts which were under study and its relation with prestige. Other questions being analysed include the problem of refusing drink and the Catholic and non-Catholic critiques of patronal feasts as based on perceptions of excessive drinking.

    Incidences of violence are elevated in night-time entertainment districts. Research suggests that safety-related behavioural strategies adopted while drinking can reduce negative alcohol-related outcomes. The current study investigates the use of safety strategies and its association with experiences of violence among patrons from the general population. Patron interviews (N = 3949) were conducted in and around licenced venues in Newcastle (New South Wales) and Geelong (Victoria) during peak trading hours (Friday and Saturday, 21:00-01:00 h). Participants (mean age = 24.3, SD = 5.8; male 54.4%) were asked to report what measures, if any, they used to keep safe when drinking and whether they had been involved in a violent incident in the last 12 months. After controlling for patron demographics and location, the use of multiple (more than one) safety strategies was significantly associated with reduced odds of involvement in a violent incident (odds ratio = 0.64, 95% confidence interval 0.49-0.85, P = 0.002). Significant gender differences were observed in the number and type of safety strategies reported. Increasing the number of safety-related behaviours during drinking occasions is associated with a small but significant reduction in experiencing alcohol-related harms, such as violence.

    The aim of this study was to investigate psychoactive drug use among nightclub patrons by analysing samples of oral fluid and compare with findings in blood samples from criminal suspects. We hypothesized that the profile of illicit drug use among nightclub patrons is different from what we observe in those forensic cases. Research stations were established outside nine popular nightclubs with different profiles and patron-characteristics in downtown Oslo. Data and sample collection was conducted on Fridays and Saturdays in March and May 2014. Individuals and groups who entered defined recruitment zones from 23:00 to 03:30 were invited to participate in this voluntary and anonymous study. Oral fluid was collected using the Intercept Oral Fluid Sampling Device. Methanol was added to increase the recovery of cannabinoids from the device. Sample preparation was performed using liquid-liquid extraction with ethyl acetate/heptane (4:1) after adding internal standards, ammonium carbonate buffer pH 9.3 and Triton X100. The first 80 samples were analysed for 122 substances, which included psychoactive medicinal drugs, classical illicit drugs and new psychoactive substances (NPS). Based on the findings and discussions with police and customs authorities, the remaining oral fluid samples were analysed for 46 substances. Among the 500 samples collected during the study period, we found illicit drugs in 25.4% and medicinal drugs in 4.2% of the samples. The most prevalent substances were: cocaine 14.6%, THC 12.4%, amphetamine/methamphetamine 2.8%, diazepam 1.2% and clonazepam 1.0%. Various NPS were found in 1.4% of the samples. The prevalence of drugs in blood samples from criminal suspects were for cocaine 3.4%, THC 34.7%, amphetamine/methamphetamine 37.0%, diazepam 12.0%, and clonazepam 29.3%. Multi-drug use was more common among criminal suspects (41.3%) than among club patrons (6.8%). The results showed that the drug use pattern among nightclub patrons was substantially

    Full Text Available 當流通館員遭遇攻擊型讀者時,由於其行為具攻擊性,常令館員窮於應對。然而,為維護圖書館服務品質,館員往往必須付出較多之「情緒勞務」,以壓抑個人生氣、委屈以及受挫等情緒感受,並努力顯露出和悅的服務態度,長期以往可能影響館員之工作效能,並對其身心健康造成負荷。爰此,本研究採取半結構式深度訪談法,從情緒勞務的層面,針對臺灣地區之大學圖書館流通館員進行研究,探討其因應攻擊型讀者之服務策略。研究結果顯示,攻擊型讀者的成因包含圖書館情境與讀者個人人格特質等因素;而受訪館員之服務策略則主要涵括處理個人負面情緒的「克制」、表達個人正面情緒的「淺層飾演」,以及處理他人負面情緒方面的「理性勸說」與「接納傾聽」等。The aggressive patrons’ outrageous and unreasonable behavior would have serious influence on circulation librarians. However, in order to maintain the service quality, “emotional labor” is usually performed by the librarians when encounter aggressive patrons. Emotional labor is the manipulation of the required emotional expression, and the strategies used to maintain the service quality. To understand circulation librarians’ service strategies coping with aggressive patrons from the perspective of emotional labor, semi-structured in-depth interviews were conducted in this study. The interviewees consisted of 15 university circulation librarians all over Taiwan. The findings revealed that the factors which may elicit aggressive reaction included library services and the patrons’ personal traits. And to cope with the aggressive patrons, the circulation librarians would employ self-controlling, surface acting, and other service strategies such as persuasion or active listening.

    This study compares the sexual behavior and HIV prevalence of men and women at social venues where people meet new sexual partners in Eastern Kinshasa with that of sexually transmitted infection (STI) treatment and antenatal clinic (ANC) patients in the same area. ANC patients, STI clinic patients, and social venue patrons were interviewed, asked to provide a blood sample on-site, and provided with information about obtaining test results. Every patron at identified social venues in the study area was invited to participate. One thousand one hundred sixteen pregnant women; 66 male and 229 female STI clinic patients; and 952 male and 247 female patrons of social venues were interviewed and tested for HIV. HIV prevalence differed by group: ANC patients (4%); female venue patrons (12%); female STI patients (16%); male venue patrons (2%); and male STI patients (23%). HIV prevalence among sex workers at social venues (29%) was higher than HIV prevalence among other female patrons with new or multiple partnerships in the past four weeks (19%) and higher than HIV prevalence among female patrons denying sex work (6%). However, the absolute number of infected women was higher among women reporting recent new or multiple partnerships than among the smaller group of sex workers (23 vs. 18). Two-thirds of the infected female STI patients (24/36) reported no more than one and no new sexual partner in the past year. Improving prevention programs in Kinshasa is essential. Prevention efforts should not neglect women at social venues who do not self-identify as sex workers but who have high rates of new sexual partnership formation.

    Studies of alcohol-related harm (violence, injury, illness) suggest that the most significant risk factors are the amount of alcohol consumed and whether obviously intoxicated patrons continue to be served. This study's objective was to investigate the effects of a responsible beverage service (RBS)/enhanced alcohol enforcement intervention on bars, bar patrons, and impaired driving. Two communities-Monroe County, New York, and Cleveland, Ohio-participated in a demonstration program and evaluation. The intervention applied RBS training, targeted enforcement, and corrective actions by law enforcement to a random sample of 10 identified problem bars in each community compared to 10 matched nonintervention problem bars. Data were collected over 3 waves on bar serving practices, bar patron intoxication, drinking and driving, and other alcohol-related harm from intervention and control bars and treatment and comparison communities. In Monroe County, New York, of the 14 outcome measures analyzed, 7 measures showed statistically significant differences from pre- to postintervention. Six of those measures indicated changes in the desired or positive direction and 2 measures were in the undesired or negative direction. Of note in the positive direction, the percentage of intervention bar patrons who were intoxicated decreased from 44 to 27% and the average blood alcohol concentration of patrons decreased from 0.097 to 0.059 g/dL pre- to postintervention. In Cleveland, Ohio, 6 of the 14 measures showed statistically significant changes pre- to postintervention with 6 in the positive direction and 4 in the negative direction. Of note, the percentage of pseudo-intoxicated patrons denied service in intervention bars increased from 6 to 29%. Of the 14 outcome measures that were analyzed in each community, most indicated positive changes associated with the intervention, but others showed negative associations. About half of the measures showed no significance, the sample sizes

    Community pharmacies vary widely in terms of ownership structures, location, and dispensing policies. It is unknown if an association exists between the type of community pharmacy and the degree of medication adherence exhibited by patrons-patients. To describe adherence to statin therapy among subjects patronizing different types of community pharmacy categories (department- mass merchandise, chain-franchise, and independent-banner) in Saskatchewan, Canada, between 2000 and 2005. Study data were obtained from the Saskatchewan Drug Plan and Extended Benefits database, which is maintained by the government of Saskatchewan, Canada. The study included all subjects who (a) filled a statin prescription within selected community pharmacies between January 1, 2000, and December 31, 2005; (b) had no record of statin prescriptions during the year prior to the first statin prescription, according to the records of the Saskatchewan Drug Plan and Extended Benefits; and (c) demonstrated active utilization in the drug plan database for at least 1 year after the first statin prescription. The proxy criterion for activity was any dispensing record for statin or nonstatin medications at least 1 year following the index claim. Statin adherence level was estimated as tablets per day, defined as the total number of tablets dispensed divided by the total number of days of observation. Each subject's observation period began on the index date and ended on the earlier of (a) 30 days after the last recorded fill for any type of prescription medication (statin or nonstatin), or (b) December 31, 2005. The primary end point was the proportion of subjects within each pharmacy category who maintained an adherence level of 80% or greater during their individual observation period. Additional adherence calculations were performed for each of 3 time periods, beginning on the index date and ending on days 365, 729, and 1094 (i.e., 1, 2, and 3 years). Patients were included in the analysis for each

    Nearly all California casinos currently allow smoking, which leads to potentially high patron exposure to secondhand tobacco smoke pollutants. Some argue that smoking restrictions or bans would result in a business drop, assuming > 50% of patrons smoke. Evidence in Nevada and responses from the 2008 California tobacco survey refute this assertion. The present study investigates the proportion of active smokers in southern California tribal casinos, as well as occupancy and PM(2.5) levels in smoking and nonsmoking sections. We measured active-smoker and total-patron counts during Friday or Saturday night visits (two per casino) to smoking and nonsmoking gaming areas inside 11 southern California casinos. We counted slot machines and table games in each section, deriving theoretical maximum capacities and occupancy rates. We also measured PM(2.5) concentrations (or used published levels) in both nonsmoking and smoking areas. Excluding one casino visit with extremely high occupancy, we counted 24,970 patrons during 21 casino visits of whom 1,737 were actively smoking, for an overall active- smoker proportion of 7.0% and a small range of ~5% across casino visits (minimum of 5% and maximum of 10%). The differences in mean inter-casino active-smoker proportions were not statistically significant. Derived occupancy rates were 24% to 215% in the main (low-stakes) smoking-allowed slot or table areas. No relationship was found between observed active-smoker proportions and occupancy rate. The derived maximum capacities of nonsmoking areas were 1% to 29% of the overall casino capacity (most under 10%) and their observed occupancies were 0.1 to over 3 times that of the main smoking-allowed casino areas. Seven of twelve visits to nonsmoking areas with no separation had occupancy rates greater than main smoking areas. Unenclosed nonsmoking areas don't substantially protect occupants from PM2.5 exposure. Nonsmoking areas encapsulated inside smoking areas or in a separate, but

    Full Text Available A small-scale patron-driven acquisition (PDA study at the University of Huddersfield is discussed in this article. The authors briefly describe the background to PDA at Huddersfield before discussing data from the 2014 PDA pilot with the e-book supplier Ebook Library (EBL. The pilot produced two sets of data, usage reports using COUNTER statistics and a short questionnaire designed by the Library. These results led to a major alteration to the collection management and development policy, where PDA is now embedded into the Library book fund.

  13. Small proportions of actively-smoking patrons and high PM2.5 levels in southern California tribal casinos: support for smoking bans or designated smoking areas

    Science.gov (United States)

    2012-01-01

    Background Nearly all California casinos currently allow smoking, which leads to potentially high patron exposure to secondhand tobacco smoke pollutants. Some argue that smoking restrictions or bans would result in a business drop, assuming > 50% of patrons smoke. Evidence in Nevada and responses from the 2008 California tobacco survey refute this assertion. The present study investigates the proportion of active smokers in southern California tribal casinos, as well as occupancy and PM2.5 levels in smoking and nonsmoking sections. Methods We measured active-smoker and total-patron counts during Friday or Saturday night visits (two per casino) to smoking and nonsmoking gaming areas inside 11 southern California casinos. We counted slot machines and table games in each section, deriving theoretical maximum capacities and occupancy rates. We also measured PM2.5 concentrations (or used published levels) in both nonsmoking and smoking areas. Results Excluding one casino visit with extremely high occupancy, we counted 24,970 patrons during 21 casino visits of whom 1,737 were actively smoking, for an overall active- smoker proportion of 7.0% and a small range of ~5% across casino visits (minimum of 5% and maximum of 10%). The differences in mean inter-casino active-smoker proportions were not statistically significant. Derived occupancy rates were 24% to 215% in the main (low-stakes) smoking-allowed slot or table areas. No relationship was found between observed active-smoker proportions and occupancy rate. The derived maximum capacities of nonsmoking areas were 1% to 29% of the overall casino capacity (most under 10%) and their observed occupancies were 0.1 to over 3 times that of the main smoking-allowed casino areas. Seven of twelve visits to nonsmoking areas with no separation had occupancy rates greater than main smoking areas. Unenclosed nonsmoking areas don’t substantially protect occupants from PM2.5 exposure. Nonsmoking areas encapsulated inside smoking areas

En la etapa de vivero, el prendimiento fue de un 100% para los patrones guayaba y "cas brasileño", mientras que para los tratamientos con "arrayán" y "cas criollo" fue de un 90%. El crecimiento vegetativo inicial fue significativamente mayor en el testigo. En el campo, se observó la misma tendencia de mayor crecimiento en el tratamiento de guayaba como patrón. También, se observó un claro efecto enanizante del patrón arrayán, mientras que los patrones "cas brasileño" y "cas criollo" mostraron un crecimiento intermedio. El número y peso de la fruta fue superior en el tratamiento de guayaba como patrón y no hubo diferencias entre los tipos de cas. Con el fin de evaluar la susceptibilidad de los patrones a nematodos en plantas adultas, se incluyó un testigo adicional de guayaba al que se le aplicó nematicida en campo. Los resultados indican que los nematodos Meloidogyne sp. y Pratylenchus sp. lograron colonizar las raíces de los tratamientos de guayaba con y sin nematicida, así como del cas brasileño. No se detectaron nematodos en las raíces de los patrones cas criollo ni de arrayán.

    Drink driving is a significant public health concern, and contributes to many road fatalities worldwide. The current study is the first to examine the prevalence and correlates of drink driving behavior in a sample of night-time entertainment precinct attendees in Australia. Interviews were conducted with 4214 night-time entertainment precinct attendees in two metropolitan and three regional cities in Australia. Seven correlates of self-reported drink driving were examined: gender, age, occupation, blood alcohol concentration (BAC), alcohol consumed prior to attending a licensed venue, energy drink consumption, and other drug consumption. Fourteen percent of night-time entertainment precinct attendees reported drink driving in the past three months. Bivariate logistic regression models indicated that males were significantly more likely than females to report drink driving in the past three months. Blue-collar workers and sales/clerical/administrative workers were significantly more likely to report drink driving behavior in the past three months than white-collar workers. The likelihood of reporting drink driving during the three months prior to interview significantly increased as BAC on the current night out increased, and when patrons reported engaging in pre-drinking or other drug use. The multivariate model presented a similar pattern of results, however BAC and pre-drinking on the night of the interview were no longer independent significant predictors. Males, blue collar/sales/clerical/administrative workers, and illicit drug consumers were more likely to report engaging in drink driving behavior than their counterparts. Interventions should focus on addressing the considerable proportion night-time entertainment precinct attendees who report engaging in drink driving behavior. Copyright © 2016 Elsevier Ltd.

    Full Text Available The murals of Christ`s Transfiguration cathedral in Polotsk (ca. 1161, which were revealed during restoration in the last several years, include several thematic strata. Among them especially notable is a group of images, related to the patron saints. Distinguished among them are the figures of the patron saints of the Polotsk ducal family, to which St. Euphrosynia of Polotsk, the founder of the monastery and the builder of the Christ`s Church, belonged. The composition “Exaltation of the Cross” is set in one row with the patron saints, thus revealing semantic correlation with the ktitors` portrait in Kiev Saint Sophia and some other Kiev churches of tenth and eleventh centuries, where the idea of Russia becoming a member of Christian community is developed. At the same time, the patron theme is deeply intertwined with the purpose of the Christ`s Church to serve as a family burial for St. Euphrosynia.

    2005-01-01

    To meet the information needs of isolated primary care providers and their patients in the US Navy, a digital health sciences library, the Virtual Naval Hospital, was created through a unique partnership between academia and government. The creation of the digital library was heavily influenced by the principles of user-centered design and made allowances for the nomadic nature of the digital library's patrons and the heterogeneous access they have to Internet bandwidth. The result is a digital library that has been in operation since 1997, continues to expand in size, is heavily used, and is highly regarded by its patrons. The digital library is dedicated to delivering the right information at the right time to the right person so the right decision can be made, and therefore the Virtual Naval Hospital functions as a knowledge-management system for the US Navy Bureau of Medicine and Surgery.

    Nightclubs are favorable environments for alcohol abuse and the use of other drugs among patrons. To identify patterns of alcohol use in a high-risk population and their relationship with sociodemographic factors and illicit drug use. A portal survey technique was used to recruit patrons in 31 nightclubs in the city of São Paulo, Brazil. A two stage sampling method allowed the selection of nightclubs and patrons within a nightclub. A total of 1057 patrons answered to a three stages-survey (nightclub entrance and exit face-to-face interviews and a day-after online questionnaire). Entrance survey offered information on sociodemographic data and history of drug use. The day-after survey used the Alcohol Use Disorders Identifications Test (AUDIT) that identified patterns of alcohol abuse disorders. Data were modeled using an ordered logit regression analysis, considering sample weights. Almost half of the nightclub patrons presented any alcohol use disorder (AUDIT score ≥8). Being male (OR = 1.68; 95% CI = 1.09-2.60) and single (OR = 1.71; 95% CI = 1.05-2.76) increased the chances for more severe alcohol use disorders. Having a graduate degree (OR = 0.57; 95% CI = 0.38-0.87) and age ≥35 years (OR = 0.48; 95% CI = 0.27-0.85) decreased the chances of patrons' alcohol use disorders. The prevalence rates of past-year marijuana, cocaine and inhalants use increased with the increased level of alcohol use disorders. Patrons of nightclubs show higher prevalence rates for any alcohol use disorders than the general population. Patrons could benefit from governmental brief intervention or referral to treatment for alcohol used disorders disclosed in nightclubs.

    Many HIV prevention interventions have been launched in gay bathhouses and sex clubs since the onset of the AIDS epidemic, such as condom distribution and HIV testing. Perhaps none of these are as intrusive to the venue's environment as what is called "monitoring," which involves staff, during every shift, repeatedly walking throughout the public areas of a bathhouse to check on patrons' sexual behavior. Yet, monitoring has received little evaluation.

ArcMap (GIS software was used to develop the floor plan instrument on which entry routes were recorded and then later analyzed. The paths analyzed were limited to what was considered the “entry area.” Data were collected during three separate one-hour periods for six consecutive days in the fall of 2008. The researcher chose three purposive one-hour time samples with the intention of distributing them across the library’s opening hours.Main results – The 1,415 patron cases used 195 unique routes that were recorded from the two entrances of the facility, with the east (right entrance accounting for 83.3% of the cases (n=1178. Two entry routes were consistently the most popular overall and across each of the sample days. The next-most- popular entry routes did not remain constant across the total observed cases and each day’s observed cases or across the sample days. Over 75% of all observed patrons used 22 of the 195 entry routes: 7 routes were used by 30 or more cases each (n=836, 59.1% of all cases, 4 by 20 to 29 cases each (n=95, 6.7% of all cases, and 11 by 10 to 19 cases each (n=159, 11.2% of all cases. The route to the circulation desk was the most popular entry route for patrons. The other most popular route passed toward the rear of the library, but the observer could not record the final destination(s of that route due to the

    Many HIV prevention interventions have been launched in gay bathhouses and sex clubs since the onset of the AIDS epidemic, such as condom distribution and HIV testing. Perhaps none of these are as intrusive to the venue's environment as what is called "monitoring," which involves staff, during every shift, repeatedly walking throughout the public areas of a bathhouse to check on patrons' sexual behavior. Yet, monitoring has received little evaluation. Between 2002 and 2004, we conducted qualitative interviews with venue managers, staff and patrons in New York City, Los Angeles, and the San Francisco Bay Area. An analysis found that monitoring was influenced by the kinds of space available for sex, suggesting three approaches to monitoring: 1) monitoring all sex in clubs that only had public areas where men had sex ; 2) monitoring some sex in clubs with private rooms for sex; and 3) no monitoring of sex, regardless of the kinds of space for sex. This paper explores each approach as described by club managers, staff, and patrons to understand the potential effectiveness of monitoring as an HIV prevention intervention.

    Purpose Use of other tobacco products (smokeless tobacco, hookah, cigarillo, e-cigarettes) is increasing, particularly among young adults, and there are few regulations on marketing for these products. We examined the associations between tobacco marketing receptivity and other tobacco product (OTP) use among young adult bar patrons (aged 18-26 years). Methods Time-location sampling was used to collect cross-sectional surveys from 7,540 young adult bar patrons from January 2012 through March of 2014. Multivariable logistic regression analyses in 2015 examined if tobacco marketing receptivity was associated (1) with current (past 30 day) OTP use controlling for demographic factors, and (2) with dual/poly use among current cigarette smokers (n=3,045), controlling for demographics and nicotine dependence. Results Among the entire sample of young adult bar patrons (Mage=23.7, SD=1.8; 48.1% female), marketing receptivity was consistently associated with current use of all OTP including smokeless tobacco (adjusted odds ratio [AOR]= 2.49, 95% confidence interval [CI] 1.90-3.27, pmarketing receptivity was significantly associated with use of smokeless tobacco (AOR=1.44, 95% CI 1.05-1.98, pmarketing receptivity.

    Full Text Available A una muestra de médicos de familia del Programa de Médicos de Familia de Niterói, Río de Janeiro, Brasil, se aplicó en abril de 2005 un cuestionario autoadministrado para determinar la percepción de los médicos de atención primaria sobre la calidad del servicio para epilepsia y los patrones de remisión y su opinión sobre la atención que se brinda. Los encuestados consideraron que los neurólogos deben ser los responsables del diagnóstico y de la prescripción inicial de medicamentos antiepilépticos, mientras que los médicos de familia se deben responsabilizar de la atención subsiguiente. Los encuestados informaron estar insatisfechos con sus conocimientos sobre la epilepsia y los medicamentos antiepilépticos. Se consideró que los profesionales mejor calificados para la atención de la epilepsia son los neurólogos (58,9%, seguidos de los médicos de familia (35,7%. Casi todos los encuestados consideraron que los lineamientos y seminarios mejoraron su capacidad para atender a sus pacientes. Los encuestados no se sentían seguros de la atención que brindaban a los pacientes con epilepsia y por lo general los remitían al neurólogo. Sin embargo, el Programa de Médicos de Familia tiene un potencial inexplotado para tratar a los pacientes con epilepsia, debido al interés de estos profesionales en mejorar su calificación.

    2018-01-01

    Full Text Available Vanessa Torres-Llenza, Pooja Lakshmin, Daniel Z Lieberman Department of Psychiatry and Behavioral Sciences, George Washington University School of Medicine and Health Sciences, Washington, DC, USA Abstract: The lack of long-term medication adherence is a challenge in the treatment of bipolar disorder, particularly during the maintenance phase when symptoms are less prominent. The rate of nonadherence is ~20%–60% depending on how strict a definition is used. Nonadherence worsens the course of bipolar disorder and can add hundreds of thousands of dollars to the lifetime cost of treating the illness. Long-acting injectable (LAI medication is an attractive alternative to daily dosing of oral medication, especially among patients who are ambivalent about treatment. The purpose of this paper is to review the evidence for the safety and efficacy of LAI aripiprazole, which was recently approved for the treatment of bipolar disorder. The approval was based on a single double-blind, placebo-controlled, multisite trial that recruited participants from 103 sites in 7 countries. A total of 731 participants with bipolar disorder were enrolled in the study. Out of that total, 266 were successfully stabilized on LAI aripiprazole and entered the randomization phase. Treatment-emergent adverse events were, for the most part, mild to moderate. Akathisia was the most common adverse event, which, combined with restlessness, was experienced by 23% of the sample. At the end of the 52-week study period, nearly twice as many LAI-treated participants remained stable compared to those treated with placebo. Stability during the maintenance phase is arguably the most important goal of treatment. It is during this period of relative freedom from symptoms that patients are able to build a meaningful and satisfying life. The availability of a new treatment agent, particularly one that has the potential to enhance long-term adherence, is a welcome development. Keywords

    A QCD model is defined to study questions of quark and gluon parton saturation at small χ-values. The model uses a source consisting of a nucleus of heavy quarkonium bound states, states well understood in QCD. Deeply inelastic scattering, using the currents j(χ)=1/4F a μν F a μν and j μ (χ)=ψγ μ ψ, is evaluated in Born and one-loop approximation in order to extract quark and gluon distributions. Quark distributions are observed to saturate while gluon distributions have a saturating and a nonsaturating component. (orig.)

    Full Text Available The leaf architecture of the species ofthe subtribe Conceveibinae is of great taxonomic value. The pattern of the secondary venation, the number of tertiary veins and the development, arrangement and forms of the areolations are the most useful characters to separate species or groups of species. The areolation is important to separate the sections; in the sect. Gavarretia has imperfect development, while the sect. Conceveiba is incomplete or developed. Venation in Conceveiba is pinnate craspedodromous or pinnate semicraspedodromous, except for C. martiana, C. ptariana, C. maynasensis, and C. pleiostemona where it is actinodromous. The number of pairs of secondary veins is usually less than 10. The tertiary venation is percurrent and frequently oblique. The marginal venation is looped and there are not  intersecondary veins. The largest venation order is between 5° and 7°; in general the veins of 4° and 5° orders are orthogonal. The results ofthis study support as well as inc1usion of Gavarretia and Polyandra in Conceveiba, and the separation of the sections Conceveiba and Gavarretia.La arquitectura foliar de las especies de la subtribu Conceveibinae es de gran valor taxonómico.

    Alcohol consumption is a recognised risk factor for HIV infection. Alcohol serving establishments have been identified as appropriate venues in which to deliver HIV prevention interventions. This paper describes experiences and lessons learnt from implementing a combined HIV prevention intervention in bar settings in one city- and one township-based bar in Tshwane, South Africa. The intervention consisted of peer-led and brief intervention counselling sub-components. Thirty-nine bar patrons were recruited and trained, and delivered HIV and alcohol risk reduction activities to their peers as peer interventionists. At the same time, nine counsellors received training and visited the bars weekly to provide brief motivational interviewing counselling, advice, and referrals to the patrons of the bars. A responsible server sub-component that had also been planned was not delivered as it was not feasible to train the staff in the two participating bars. Over the eight-month period the counsellors were approached by and provided advice and counselling for alcohol and sexual risk-related problems to 111 bar patrons. The peer interventionists reported 1323 risk reduction interactions with their fellow bar patrons during the same period. The intervention was overall well received and suggests that bar patrons and servers can accept a myriad of intervention activities to reduce sexual risk behaviour within their drinking settings. However, HIV- and AIDS-related stigma hindered participation in certain intervention activities in some instances. The buy-in that we received from the relevant stakeholders (i.e. bar owners/managers and patrons, and the community at large) was an important contributor to the feasibility and acceptability of the intervention.

    Objectives. We described frequency of secondhand smoke (SHS) exposure among young adults patronizing bars and associations between SHS exposure, attitudes, and smoking behavior. Methods. We collected cross-sectional surveys from randomized time–location samples of bar patrons aged 18 to 26 years in San Diego, California, and Oklahoma City and Tulsa, Oklahoma, in 2010 to 2011. Multivariate logistic regression evaluated associations between SHS exposure, attitudes about dangers of SHS, susceptibility to smoking initiation among nonsmokers, and quit attempts among current smokers. Results. More than 80% of respondents reported past 7-day exposure to any SHS, and more than 70% reported exposure at a bar. Current smokers reported more SHS exposure in cars and their own homes than did nonsmokers. Among nonsmokers, SHS exposure was associated with susceptibility to initiation, but those who believed that SHS exposure is harmful were less susceptible. Belief that SHS is dangerous was associated with quit attempts among smokers. Conclusions. Smoke-free environments and education about the harms of SHS may decrease tobacco use among young adults who frequent bars, where they are heavily exposed to SHS. PMID:24028259

    Full Text Available College students are accessing virtual libraries whether they are on campus or learning from a distance. Academic institutions serving virtual patrons must remain focused on meeting the needs of those library users by continually examining their preferences, their searching behavior, and the information they seek. The purpose of this research was to determine if virtual patrons are satisfied with the resources and services being provided by a university’s online library. Following a web-based survey, demographic characteristics of students were analyzed to determine if any influenced students’ satisfaction. Using analysis of variance, correlation, and descriptive statistics, several demographic factors were found to influence student satisfaction with the library’s online resources: age, gender, achieved educational level, student status, and computer experience. One factor, computer experience, was found to influence student satisfaction with the library’s online services. Overall, students reported satisfaction with the university’s online library resources and services. Comments submitted to open-ended questions regarding areas for improvement to the online library provide library administrators with avenues for development to increase awareness of library services, focus improvement in navigation, and enhance student satisfaction.

    Gender-based violence is a well-recognized risk factor for HIV infection among women. Alcohol use is associated with both gender-based violence and sexual risk behavior, but has not been examined as a correlate of both in a context of both high HIV risk and hazardous drinking. The purpose of this paper is to examine the association between recent abuse by a sex partner with alcohol and sexual risk behavior among female patrons of alcohol serving venues in South Africa. Specifically, the aim of this study is to determine whether sexual risk behaviors are associated with gender-based violence after controlling for levels of alcohol use. We surveyed 1,388 women attending informal drinking establishments in Cape Town, South Africa to assess recent history of gender-based violence, drinking, and sexual risk behaviors. Gender-based violence was associated with both drinking and sexual risk behaviors after controlling for demographics among the women. A hierarchical logistic regression analysis showed that after controlling for alcohol use sexual risk behavior remained significantly associated with gender-based violence, particularly with meeting a new sex partner at the bar, recent STI diagnosis, and engaging in transactional sex, but not protected intercourse or number of partners. In South Africa where heavy drinking is prevalent women may be at particular risk of physical abuse from intimate partners as well as higher sexual risk. Interventions that aim to reduce gender-based violence and sexual risk behaviors must directly work to reduce drinking behavior.

    Despite the development of more researched and formulated orthodox medicines, herbal medicines continue to be well patronized for persons across the world with some patrons concurrently using both forms, oblivious of the unwanted effects that may occur. Using a multistage sampling procedure, a semistructured questionnaire was used to collect data in April 2016 from 240 informants from three selected hospitals and three herbal clinics in Tamale, a city in northern Ghana. Using Statistical Package for the Social Sciences, binary logistic regression was used to determine sociodemographic predictors of concurrent use of herbal and orthodox medicines. Orthodox medicines were the drug of choice for 54.2% and 49.2% of patrons of hospitals and herbal clinics, respectively. Also, 67.5% of herbal clinic patrons used orthodox medicines, while 25.0% of hospital attendees used herbal medications prior to their visit to the health facilities. Up to 17.9% of respondents concurrently used herbal and orthodox medicines for their prevailing ailment with age, less than 30 years being the only predictor of this habit (p = 0.015; 95% CI, 1.183–4.793; cOR = 2.4). All health professionals including those in herbal clinics should therefore be interested in the drug history of their clients. PMID:29743917

    Full Text Available Richardson’s 143-page book provides an interesting account on the life of Alexander Hardcastle (London, 1872 – Agrigento, 1933, a rich English patron and archaeologist, who operated in Sicily during the early twentieth century. Son of Hernt and Marie Sophie Hardcastle Herschel, Alexander took his military service in the Royal Navy, gaining a thorough technical knowledge, which he successfully used in Sicily. After he obtained a passport in December 1920, Hardcastle moved to Girgenti (now Agrigento, where he purchased a new house, the so-called Villa Aurea , and allocated private funds to perform excavations and massive renovation works at the nearby Greek temples of Akragas . In particular, he restored eight columns of the Temples of Herakles  and Demetra , and excavated part of the ancient city walls in the 1920s. His activity caused a great sensation in both Sicily and Great Britain, as articles in newspapers clearly testify.

    Any effort to decrease the toll of drunk driving must include efforts directed at people who drink in bars, particularly young adults who use motor vehicles after drinking. We designed a multifaceted social marketing campaign, Last Call, to increase the use of designated drivers and safe rides homes among 21-34-year olds. There were three components to the intervention: (1) use of taxi stands to promote taxi use; (2) point-of-sale information to patrons at partner bars and (3) a mass media campaign to support the designated driver/safe ride home message. Among the heaviest drinkers, the programme significantly increased the use of designated drivers and increased the use of taxis by 63%.

    Full Text Available As digital comic book consumption continues to rise in popularity, the comic book community appears conflicted over the effects that digital scans have on the meaning of collecting and reading comic books. Historically, comic ownership served as the locus of comic fan social capital; will digital scans hold the same cultural capital as printed books? And does postpurchased digital scan dissemination primarily hurt copyright holders through lost sales, or does it help through social promotion? Building on an analysis of fan attitudes toward digital comic book texts, we seek to account for the limitations of locality by surveying the attitudes of comic book store patrons concerning their attitudes toward physical and digital comic book texts.

    With funding through NASA's Science Mission Directorate, the NASA @ My Library project has been working with the public library community to enhance the STEM literacy of library patrons throughout the nation. One element of the project is to disseminate a variety of materials to 75 partner libraries in order to support their implementation of hands-on, NASA related STEM activities for their patrons. These materials range from very low tech (UV beads) to high tech (a 4.5" Orion Dobsonian telescope), and include an 8" tablet. This tablet provides us with a wide range of possibilities for delivering NASA content. Besides NASA multimedia and real-time spacecraft data, the tablets can be used for interactive activities, including public apps as well as apps specifically designed for this program, such as a green screen app that incorporates NASA imagery as part of a larger storytelling activity. The tablets also include a full sensor suite (magnetometer, light sensor, accelerometer, etc.), allowing us to develop library activities that use the tablet as a measuring device - detecting magnetism in a "Meteorite or Wrong" activity, or using the light sensor as a transit device. The tablet is centrally managed and includes a "kiosk mode", allowing the libraries to use it in either a locked down or conventional mode. The management system also allows us to create a curated collection of apps and multimedia, push out updated software, and collect analytics data on how the tablet is being used. In this presentation we will discuss the library pre-survey that guided our tablet development process, as well as our lessons learned to date, including the practicality and effectiveness of deploying tablets at this scale, their ability to support NASA specific STEM efforts, and what we have learned about library usage.

    Full Text Available In this study, we analyzed the biogeographic patterns of the Chilean littoral fish fauna, including latitudinal trends in teleost and chondrichthyan fish species richness, their distribution range patterns, and their level of endemism, both to the Chilean coast and the Southeastern Pacific. We determined the number and percentage of fish taxa within four different groups based on their biogeographic affinities. This was done, both for teleost and chondrichthyan fishes, at the species, genus and family level. In order to recognise the existence of biogeographic regions, we applied cluster and ordination analyses to the distribution data, using objective bootstrapping techniques at the three taxonomic levels used. We found that littoral fish diversity remains fairly constant along the coast down to around 40º S, declining south of this latitude. We detected two biogeographic regions along the Chilean coast, with a break between them at 40º S. These results lend support to previously recognized biogeographic provinces or faunistic units. These two biogeographic regions are a reflection of the mixed origin of the Chilean littoral ichthyofauna, consisting of northern warm-temperate fishes of subtropical origin and southern cold-temperate fishes of subantarctic origin. While the percentage of fishes endemic to the Chilean coast is not high (18%, a large percentage of teleost species inhabiting Chilean littoral waters are endemic to the Southeastern Pacific (44%. Dispersal and evolutionary history, rather that other factors, seem to explain the observed patterns of distribution of this particular fish fauna. This study represents a necessary first step towards understanding the biogeography of Southeastern Pacific marine fishesEn este estudio, analizamos los patrones biogeográficos de los peces litorales chilenos, incluyendo las tendencias latitudinales en riqueza de especies de peces teleosteos y condrictios, sus rangos de distribución, y nivel de

    Electronic nicotine delivery systems (ENDS, often called e-cigarettes) are nicotine delivery devices that heat nicotine into vapour that is inhaled, a process called 'vaping'. Use eclipsed nicotine-replacement therapy (NRT) in 2014 but ENDS role in smoking cessation remains controversial. Safety has not been proven and there have been reports to US poison centres regarding potential ENDS-related nicotine toxicity. A further concern is use of ENDS to vape recreational drugs, but there is limited data to substantiate this. The aim of this study was to report on ENDS use to vape recreational drugs in patrons of a South London nightclub where high prevalence of recreational drug use has previously been shown. A convenience sample of 101 participants was surveyed in March 2015 as part of a larger survey on drug use. Individuals were asked if they used ENDS to vape nicotine and/or other substances (and if so which substances). Ninety (89.1 %) of respondents were male with median age of 28 years (IQR 23-34). Eighty (79.2 %) currently smoked cigarettes; 20 (19.8 %) currently used ENDS for nicotine. Six (5.9 %) reported using ENDS to take other substances: 2 for 'liquid cannabis' and 4 did not elaborate on the substance(s) used. Of these 6, 3 were using ENDS to vape nicotine and 3 had never used them for nicotine. 5.9 % of individuals in this sample reported using ENDS to vape substances other than nicotine. Further work is required in larger populations to determine how common this is, evaluate which agents are being vaped and to inform appropriate public education.

    Full Text Available The structures of microcline perthites collected from granitic pegmatites have been studied at different observation scales using optical microscopy (OM, X-ray diffraction (XRD, 27Al MASS-NMR spectroscopy, and electron microprobe (EMPA with Na mappings. Pegmatite perthites are identified as complex systems. During the cooling process, K-rich feldspars display two separated genetic periods of recrystallization, each one with variable intensity along different samples. During the first period, in the mineral structure a progressive construction of macrostructural pseudo-periodic patterns is produced. These regular patterns emerge due to a combined mechanism of non-ergodic Si/Al local ordering and a global cooperative effect of the crystal structure. From the incoherent Na/K interfaces arise transformation fronts (avalanches which can coalesce longitudinally and juxtapose transversally to self-assemble into irregular domains. Finally, they can evolve up to create regular twin-domains (Albite and Pericline laws as the crystal unit of the macrostructural building. This selforganization process is activated when the system is open to water circulation acting as a catalyst of Al/Si ordering in the feldspar lattice linked with an external stimulation by shear tectonic stress. During the second period the structural patterns, previously created, are destroyed by (i relaxation and deformation twinning mechanisms, (ii coarsening of twin-domains produced by dissolution-precipitation due to aqueous fluids interactions at low temperature, (iii reorientation of Periclinelaw twin-domains to the Albite-law orientation.

It is unclear if all 24 interviews took place in the same library. Reference interviews that took place during the times the researcher was on site and did not relate to the use of the public computer terminals were included in the study.During each interaction, the researcher compared the patron’s behaviour to a checklist of traits relating to assertiveness and responsiveness. For example, more assertive behaviours included moving and talking quickly and sustained eye contact. Less assertive behaviours included “waiting to be asked” and soft speech (p. 127. More responsive behaviours usually consist of a greater willingness to engage on an emotional level with the librarian and more open facial expressions and gestures.The balance of behaviours across the two categories was used by the researcher to determine which of the following social style categories a patron belonged to: driver, analytical, amiable, or expressive. Drivers, described in social style theory as “practical and task orientated,” were those who demonstrated “less responsive” and “more assertive” behaviours at the desk (pp. 127‐128.

    With an estimated 2.5 million people living with HIV/AIDS, India has the third highest number of HIV-infected people in the world. Despite reductions in prevalence among the general population, the percentage of all infections occurring among Indian women is continuing to rise. Women s risk of HIV infection from their partner and observed associations between sexual violence and HIV infection in India underscore the importance of understanding determinants of forced sex. A probability survey was conducted from June 2003 to August 2007 in Chennai, India among alcohol venue (“wine shops”) patrons to estimate the prevalence of sexual violence and to identify risk factors associated with perpetrating forced sex. Among 1499 men, 28.5% reported forced sex with at least one partner in the past 3 months. In multivariate analysis, earning income for less than 12 months a year, visiting the wine shop with friends, STD symptoms, perpetration of physical violence, and number of sexual partners were statistically significantly associated with perpetrating forced sex. Men who reported having 3 or more close friends were less likely to perpetrate violence. HIV interventions that facilitate formal groups that foster positive social support and address a range of HIV risk behaviors including sexually and physically abusive behaviors are recommended to reduce sexual violence.

    Full Text Available Objective – The purpose of this study was to analyze the data from a referencestatistics-gathering mechanism at Colorado State University (CSU Libraries. It aimedprimarily to better understand patron behaviours, particularly in an academic librarywith no reference desk.Methods – The researchers examined data from 2007 to 2010 of College LiaisonLibrarians’ consultations with patrons. Data were analyzed by various criteria,including patron type, contact method, and time spent with the patron. Theinformation was examined in the aggregate, meaning all librarians combined, andthen specifically from the Liberal Arts and Business subject areas.Results – The researchers found that the number of librarian reference consultationsis substantial. Referrals to librarians from CSU’s Morgan Library’s one public servicedesk have declined over time. The researchers also found that graduate students arethe primary patrons and email is the preferred contact method overall.Conclusion – The researchers found that interactions with patrons in librarians’ offices – either in person or virtually – remain substantial even without a traditional reference desk. The data suggest that librarians’ efforts at marketing themselves to departments, colleges, and patrons have been successful. This study will be of value to reference, subject specialist, and public service librarians, and library administrators as they consider ways to quantify their work, not only for administrative purposes, but in order to follow trends and provide services and staffing accordingly.

    Full Text Available An extensive faunistic database has been set up gathering bibliographic information, data from scientific collections and other relevant unpublished data from the 143 species of continental Portuguese butterflies and burnets (Superfamily Papilionoidea, Families Hesperiidae and Zygaenidae. This database was used to define distribution patterns through the application of factorial correspondence analysis (FCA to the matrices of frequency and presence-absence data in a 50 x 50 km UTM grid. The identification of faunistic elements and regions was obtained through an automatic application of the classification analysis to the FCA results. In a second instance, we used the same methodology to establish the relationship between previously obtained patterns and a set of environmental variables, in order to determine the factors related to the observed classes. The annual average temperature proved to be the best factor to explain the observed latitudinal gradient in the butterfly distribution. The results show a well-defined northern interior region of high average altitudes and limited in the South by the Serra da Estrela. This area has the largest species richness and hosts the Montesinho Natural Park, which is the most diverse in the country. In the southern half of Portugal, the Algarve deserves a special mention for its group of species with typical Mediterranean requirements.

    The aim of this study was to determine the prevalence of Listeria spp. and Listeria monocytogenes (L. monocytogenes) in urban public lavatories and on shoe soles of facility patrons in a European capital city. More than 91% of all municipal public lavatories in Vienna close to public hubs were included in this study. Overall, 373 swab samples of public lavatories and shoes of facility patrons were enriched, according to ISO 11290-1. Listeria monocytogenes isolates were subtyped using pulsed-field gel electrophoresis. A total of 24 samples were positive for Listeria spp., yielding an overall prevalence of 6.4% (24/373). Listeria monocytogenes was found in 2.1% (8/373) of all samples. Swabs from lavatories in parks, container lavatories and lavatories at markets had the highest prevalences of 20.7% (6/29), 20% (2/10) and 12.5% (1/8) Listeria spp., respectively. These detection rates were statistically significantly higher than those associated with lavatories in shopping centres (P = 0.003, P = 0.002, P = 0.02) and at public transport locations (P = 0.0004, P = 0.005, P = 0.02). Shoes sampled at Christmas markets showed the highest Listeria spp. and L. monocytogenes prevalences of 80% (4/5) and 40% (2/5), respectively. With regard to shoe type, Listeria spp. detection rates were 14.3% (3/21; winter boots), 13.3% (2/15; hiking boots), sport shoes (5.9%; 2/34) and brogues (5.1%; 4/79). No Listeria spp. were found on shoe soles that had smooth treads (0/76), while Listeria spp. were detected on 19.5% (8/41) of medium depth tread shoe types and on 9.4% (3/32) of deep tread shoes. These data suggest that soil environment is still one of the most important reservoirs for the foodborne pathogen L. monocytogenes. © 2014 Blackwell Verlag GmbH.

    Full Text Available El objetivo de este artículo fue proponer una colección no exhaustiva de 36 patrones para el diseño de interacciones en aplicaciones sociales para adultos mayores. La propuesta representa un punto de partida confiable para facilitar, a diseñadores/desarrolladores, la integración de usabilidad en las interfaces de estas tecnologías con el fin de fomentar su aceptación, uso y adopción entre los adultos mayores. Esta propuesta se basa en esfuerzos previos comúnmente expresados como criterios y guías de diseño para definir los posibles problemas de usabilidad en este tipo de interfaces, y se concentra en reforzar estos enfoques mediante la integración de una mayor descripción de tales anomalías y alternativas de solución bajo una estructura de patrones útil para los diseñadores/desarrolladores. Se realizó un estudio de usabilidad con la técnica «evaluación heurística» (comúnmente utilizada en interacción hombre-máquina para obtener la percepción de los usuarios sobre un diseño particular. El trabajo se llevó a cabo desde dos perspectivas: el punto de vista de expertos técnicos y la percepción de un grupo social de adultos mayores. Los resultados reflejaron que los patrones propuestos propician la creación de interfaces bien diseñadas capaces de ofrecer una mejor experiencia de uso y promueven un impacto positivo en la calidad de vida de los adultos mayores.

    2005-01-01

    Full Text Available El cráneo humano es una estructura ósea compleja, formada por un conjunto de huesos que se organizan en estructuras jerárquicas y que responden a diversos patrones ontogénicos y funcionales. El concepto de integración morfológica está en la base de la comprensión de la morfogénesis y evolución del cráneo humano. El objetivo del presente estudio consiste en identificar patrones de covariación fenotípica entre estructuras craneales definidas a priori según un criterio funcional. Se analizó una muestra de 340 individuos adultos, procedentes de Hallstatt (Austria, mediante técnicas de Morfometría Geométrica. Para cada espécimen se digitalizaron 45 puntos craneométricos en forma de coordenadas 3D. Diferentes configuraciones de puntos reflejan la forma de cada componente funcional. Los patrones de covariación fueron estimados mediante análisis de Partial Least Squares. Los resultados indican que la base es una pieza clave en la integración morfológica del cráneo, puesto que muestra una fuerte covariación con todo el resto de estructuras. Cuando se consideran componentes funcionales discretos, se observa que los faciales tienden a covariar entre sí. Lo mismo sucede en los neurocraneales. En cambio, si se consideran conjuntamente, muestran una relativa independencia.

Dicha variación estacional en los patrones de comportamiento se considera poco conocida en delfines que habitan aguas tropicales. El delfín manchado (forma costera Stenella attenuata graffmani, parece ser la única especie de cetáceo residente en el Golfo de Papagayo, área que se caracteriza por una estacionalidad muy bien definida. El objetivo de este trabajo es determinar si esta estacionalidad influencia el tamaño del grupo, la presencia y patrones de comportamiento de esta especie de delfín en el golfo. Usando transectos en banda se recorrieron dos localidades del Golfo de Papagayo. El tamaño del grupo varío de uno a 50 individuos, con una media de 10.16 (DS =9.61. Las actividades alimentarias fueron más intensas que las interacciones sociales y de desplazamiento, las cuales siguieron un ordenamiento diario y estacional. Se describieron dos técnicas principales de forrajeo las cuales parecen estar asociadas con el tamaño del grupo y localidad dentro del golfo. La variación diaria en los patrones de comportamiento parecen estar relacionados con la disponibilidad, distribución, y arreglo espacial de las presas. De igual manera, la variación estacional de estas actividades probablemente esta asociada por la disponibilidad de alimento, tal como ha sido observado en un mayor número de grupos y una mayor inversión de tiempo en actividades de alimentación durante la época seca y finales de las lluviasOccurrence and behavioral patterns of the spotted coastal dolphin Stenella attenuata (Cetacea: Delphinidae in the Gulf of Papagayo, Costa Rica.

    Full Text Available Food service industry is growing rapidly as a result of the changing consumer lifestyle. The food service industry is highly competitive due to the increasing number of new entrants offering inventive food products and services. In order to be outstanding in such competitive industry, retailers nowadays opt to emphasize on their store environment. Past studies discovered that store environment stimulates emotions that significantly boost customer revisit intention. As a result, retailers attempt to differentiate their store by combining various environmental stimuli to create an attractive ambience that will in turn draw in the customers. Hence, this study attempts to investigate the impact of various café ambience factors on the patrons’ revisit intention. The patrons of cafes in Ipoh, Perak were selected using purposive sampling technique to be the respondents of this study. 250 questionnaires were collected and Partial Least Square technique was used to analyse the data collected. Findings show that all the five factors of café ambience namely lighting, music, decoration, cleanliness and layouts were significantly influencing the patrons’ revisit intention. Of these five factors, lighting was most influential while music was the least influential in affecting the patrons’ revisit intention. Accordingly, this study lists several recommendations for practitioners and academics with regards to the store environment and its impact on the repurchase intention.

    A preliminary study transient on the natural convection that occurs within a laboratory still is presented. The reason for this work was to have a better understanding of the transport phenomena, to determine the manner in which it produces an effect in the operation of booth type still. The evolution of the temperature patterns and relation to the flow that is visualized in the interior of the still, with a constant temperature increase on the base of the same analyzed. The still used is composed of a stainless steel base of 1 x 0.5 m under which distilled water is made to circulate at a given temperature. The upper walls, that form an isosceles triangle of 45 Celsius degrees with a height of 0.40 m, are composed two layers of transparent glass in the middle of which the water is made to circulate at a controlled temperature. The flow patterns were visualized using smoke, illuminated with a laser sheet.

    Full Text Available Utilizando datos del Registro Nacional de defunciones de los años 1996-2005 se calcularon las tasas de mortalidad estandarizadas por edad para personas nacidas en Nicaragua versus personas nacidas en Costa Rica. Así mismo, utilizando modelos de regresión binomial se determinaron los riesgos relativos de mortalidad de los inmigrantes nicaragüenses versus personas nativas de Costa Rica con ajustes por edad, urbanización, desempleo, pobreza, educación y segregación residencial. Los hombres y mujeres nacidos en Nicaragua tuvieron un riesgo reducido de mortalidad de 32% y 34% respectivamente con relación a sus contrapartes nacidas en Costa Rica. Se notó que los riesgos de mortalidad por enfermedades infecciosas, cáncer, enfermedades crónicas pulmonares, enfermedades cardiovasculares, y enfermedades crónicas del hígado eran significativamente reducidos entre los inmigrantes nacidos en Nicaragua. El exceso significativo de mortalidad por homicidios se encontró entre los hombres nacidos en Nicaragua (RT = 1,35, 95% IC: 1,19; 1,53 y en mujeres (RT = 1,41, 95% IC: 1,02; 1,95. El riesgo relativo de causas de mortalidad de origen de tipo exógeno entre los inmigrantes nicaragüenses fue más grande entre los grupos de edad joven en áreas de baja densidad de inmigrantes nicaragüenses. La población nacida en Nicaragua residiendo en Costa Rica tiene un riesgo reducido de mortalidad por causas generales versus las personas nacidas en Costa Rica en los años entre 1996-2005. Esto se debe a una mortalidad por enfermedad reducida, la cual es bastante marcada. El homicidio es un una razón de mayor mortalidad entre los inmigrantes nacidos en Nicaragua versus los nativos costarricenses. Hay una gran necesidad de llevar acabo investigaciones adicionales sobre el rol de la migración, estatus socioeconómico y comportamientos entorno a la salud para poder explicar más a fondo los patrones de mortalidad diferenciales entre los inmigrantes nicarag

    Full Text Available This study examined the relationship between patron demographics, substance use, and experience of recent alcohol-related accidents and injuries that were not due to interpersonal violence in night-time entertainment districts. Cross-sectional interviews (n = 4016 were conducted around licensed venues in entertainment districts of five Australian cities. Demographic factors associated with non-violent alcohol-related injuries were examined, including gender, age, and occupation. The association between substance use on the night of interview; blood alcohol concentration (BAC, pre-drinking, energy drink consumption, and illicit drug use; and experience of injury was also explored. Thirteen percent of participants reported an alcohol-related injury within the past three months. Respondents aged younger than 25 years were significantly more likely to report an alcohol-related injury. Further, a significant occupation effect was found indicating the rate of alcohol-related injury was lower in managers/professionals compared to non-office workers. The likelihood of prior alcohol-related injury significantly increased with BAC, and self-reported pre-drinking, energy drink, or illicit drug consumption on the night of interview. These findings provide an indication of the demographic and substance use-related associations with alcohol-related injuries and, therefore, potential avenues of population-level policy intervention. Policy responses to alcohol-related harm must also account for an assessment and costing of non-violent injuries.

Specifically, the study compares the degree of answer completion and the level of user satisfaction for simple factual questions vs. more in‐depth subject‐based reference questions, and for ‘local’ (pertaining to a particular library and non‐local questions.Design – Content analysis of 415 transcripts of reference transactions, which were also compared to corresponding user satisfaction survey results.Setting – An online collaborative reference service offered by a large public library system (33 branch and regional locations. This service is part of the Metropolitan Cooperative Library System: a virtual reference consortium of U.S. libraries (public, academic, special, and corporate that provides 24/7 service.Subjects – Reference librarians from around the U.S. (49 different libraries, and users logging into the service via the public library system’s portal (primarily patrons of the 49 libraries. Method – Content analysis was used to evaluate virtual reference transcripts recorded between January and June, 2004. Reliability was enhanced through triangulation, with researchers comparing the content analysis of each transcript against the results of a voluntary exit survey. Of 1,387 transactions that occurred during the period of study, 420 users completed the survey and these formed the basis of the study, apart from 5 transactions that were omitted because the questions were incomprehensible. Questions were examined and assigned to five categories: “simple, factual questions; subject‐based research questions; resource access questions; circulation‐related questions; and local library information inquiries” (80‐81. Answers were classed as either “completely answered, partially answered or unanswered, referred, and problematic endings” (82. Lastly, user satisfaction was surveyed on three

    2013-01-01

    Full Text Available La diferenciación rápida de colonias bacterianas es esencial en muchos campos industriales, científicos y de salud humana y animal. Generalmente esa diferenciación se logra por técnicas microscópicas, bioquímicas o genéticas muy elaboradas que requieren tiempo y entrenamiento. En este estudio se utilizaron técnicas de análisis de imágenes sobre patrones de difracción de luz láser para evaluar su sensibilidad en la diferenciación de colonias bacterianas. Adicionalmente se estudió el efecto del tiempo de crecimiento de las colonias en la generación de estos patrones y se determinó la influencia de la cantidad de medio de cultivo en la difracción de luz láser. Los patrones de difracción del láser se obtuvieron sobre cultivos puros de cinco aislamientos bacterianos B1, B2, B3, B2Ca y B2Cb. En la primera prueba de diferenciación se utilizaron colonias de B2, B3, B2Ca. En el estudio del efecto del tiempo de crecimiento sobre patrones de difracción, las bacterias B1 y B2Cb con uno o dos días de crecimiento. Finalmente, el efecto de la cantidad de medio de cultivo en la difracción de la luz, se evaluó en una prueba en cajas petri con 10, 15 o 20 ml de medio de cultivo estéril sin colonias de bacterias. Mediante un análisis de escalado multidimensional realizado con los parámetros de textura extraídos de las imágenes de los patrones, se obtuvo un agrupamiento adecuado de los patrones asociados a las colonias de cada bacteria evaluada, lo cual indicó que las colonias bacterianas se pueden diferenciar por sus patrones de difracción. Adicionalmente se encontró que no hay variaciones significativas en los patrones de difracción obtenidos de dos aislamientos bacterianos en dos tiempos de crecimiento. El espesor del medio de cultivo afectó la difracción del haz de luz pues patrones obtenidos de cajas petri con 10 ml se separan completamente de los patrones obtenidos con 15 y 20 ml, aunque no hay diferencias entre los dos

    2013-01-01

    Libraries in the USA and globally are undergoing quiet revolution. Libraries are moving away from a philosophy that is collection-centered to one focused on service. Technology is key to that change. The Patron Driven Library explores the way technology has moved the focus from library collections to services, placing the reader at the center of library activities. The book reveals the way library users are changing, and how social networking, web delivery of information, and the uncertain landscape of e-print has energized librarians to adopt technology to meet a different model of the library while preserving core values. Following an introduction, the first part begins with the historical milieu, and moves on to current challenges for financing and acquiring materials, and an exploration of why the millennial generation is transformational. The second part examines how changes in library practice can create a culture for imagining library services in an age of information overflow. The final chapter asks: ...

    Directory of Open Access Journals (Sweden)

    Síofra McSherry

    2017-07-01

    Full Text Available This paper focuses on material and financial gifts received by the American modernist poet Marianne Moore (1887-1972 under the auspices of patronage. Extrapolated from Moore’s letters, archival ephemera, and the work of her biographers, Moore’s main patronage relationships are analyzed as gift exchange cycles encompassing financial support, material gifts, and the writing produced by the poet. The reading draws from ethnographic literature on the gift economy in the tradition of Marcel Mauss, Claude Lévi-Strauss, and Lewis Hyde. After a brief outline of the role of the patron in the avant-garde circles of the early 1920s, Moore's interactions with several key benefactors are examined: Scofield Thayer, James Sibley Watson Jr., and Bryher. The paper aims to demonstrate first, how patronage may be considered a gift economy, outlining the effects and functions of such a system, and second, how such a reading may assist in the interpretation of patronage interactions.

    While investigating an outbreak of gastrointestinal disease associated with a restaurant, the New York City Department of Health and Mental Hygiene (DOHMH) noted that patrons had reported illnesses on the business review website Yelp (http://www.yelp.com) that had not been reported to DOHMH. To explore the potential of using Yelp to identify unreported outbreaks, DOHMH worked with Columbia University and Yelp on a pilot project to prospectively identify restaurant reviews on Yelp that referred to foodborne illness. During July 1, 2012-March 31, 2013, approximately 294,000 Yelp restaurant reviews were analyzed by a software program developed for the project. The program identified 893 reviews that required further evaluation by a foodborne disease epidemiologist. Of the 893 reviews, 499 (56%) described an event consistent with foodborne illness (e.g., patrons reported diarrhea or vomiting after their meal), and 468 of those described an illness within 4 weeks of the review or did not provide a period. Only 3% of the illnesses referred to in the 468 reviews had also been reported directly to DOHMH via telephone and online systems during the same period. Closer examination determined that 129 of the 468 reviews required further investigation, resulting in telephone interviews with 27 reviewers. From those 27 interviews, three previously unreported restaurant-related outbreaks linked to 16 illnesses met DOHMH outbreak investigation criteria; environmental investigation of the three restaurants identified multiple food-handling violations. The results suggest that online restaurant reviews might help to identify unreported outbreaks of foodborne illness and restaurants with deficiencies in food handling. However, investigating reports of illness in this manner might require considerable time and resources.

    Full Text Available The aim of this study was to obtain a culturally adapted Spanish version of the “Revised family communication patterns instrument (RFCP, using rigorous procedures in the retro-translation process and in the subsequent empirical study. The sampling consisted of 455 university students and two subscales for the conversation orientation were obtained (“Ideas expression” and “Differences acceptance” and two for the conformity orientations (“Differences rejection” and “Obedience encourage”. All the scales proved to have good psychometric qualities and suitable convergent, concurrent and content validity, yet it is necessary to go more deeply into the conformity orientation. The construct validity was supported by a confirmatory factorial analysis showing that the RFCP is a useful instrument for family assessment. El objetivo de este estudio ha sido obtener una versión española adaptada culturalmente del instrumento “Patrones de comunicación familiar (PCFR, versión revisada, empleando procedimientos rigurosos en el proceso de retrotraducción y en el estudio empírico posterior.

    Full Text Available La medición de descargas parciales (DP se sustenta en la detección y filtraje de pulsos de corriente que aparecen en una banda de frecuencia que abarca desde los kilohertzios hasta los gigahertzios, por tal motivo los detectores de descargas parciales (DDP poseen sistemas para desagregar dichos pulsos de corriente. Sin embargo, los DDP también permiten el paso de otras señales de alta frecuencia (ruidos que se mezclan con los pulsos de DP y afectan la medición, interpretación y caracterización de las DP. Para atenuar ese efecto, se han desarrollado distintas técnicas para separar los ruidos tanto asociados a las señales como los existentes en los patrones φ,q,n.  En este artículo se presentan los resultados obtenidos en la reducción de los ruidos asociados a la conmutación de tiristores y los ruidos esporádicos, de los patrones φ,q,n mediante el empleo de técnicas de procesamiento de imágenes digitales. The measurement of partial (PD discharges is sustained in the detection and filtration of current pulses which appear in a band of frequency that include from the kilohertz until the gigahertzios, for such a reason the detectors of partial (PDD discharges they possess systems for the separation of this current pulses. However, PDD also allows the step of other signals of high frequency, denominated noises, that mix with the pulses of PD and they affect measurement, interpretation and characterization of PD. To attenuate that effect, different techniques have been developed to separate the noises so much associated to the signs like the existent ones in the φ,q,n patterns. In this paper are presented the results obtained in the noise reduction of the noises associated to the thyristor’s commutation and the sporadic noises, in the φ,q,n patterns by means of the technical of digital images processing

    Background Despite efforts to reduce exposure to secondhand smoke (SHS), only 5% of the world's population enjoy smoke-free restaurants and bars. Methods Lifetime excess risk (LER) of cancer death, ischaemic heart disease (IHD) death and asthma initiation among non-smoking restaurant and bar servers and patrons in Minnesota and the US were estimated using weighted field measurements of SHS constituents in Minnesota, existing data on tobacco use and multiple dose-response models. Results A continuous approach estimated a LER of lung cancer death (LCD) of 18×10−6(95% CI 13 to 23×10−6) for patrons visiting only designated non-smoking sections, 80×10−6(95% CI 66 to 95×10−6) for patrons visiting only smoking venues/sections and 802×10−6(95% CI 658 to 936×10−6) for servers in smoking-permitted venues. An attributable-risk (exposed/non-exposed) approach estimated a similar LER of LCD, a LER of IHD death about 10−2 for non-smokers with average SHS exposure from all sources and a LER of asthma initiation about 5% for servers with SHS exposure at work only. These risks correspond to 214 LCDs and 3001 IHD deaths among the general non-smoking population and 1420 new asthma cases among non-smoking servers in the US each year due to SHS exposure in restaurants and bars alone. Conclusions Health risks for patrons and servers from SHS exposure in restaurants and bars alone are well above the acceptable level. Restaurants and bars should be a priority for governments’ effort to create smoke-free environments and should not be exempt from smoking bans. PMID:23407112

    Full Text Available El objetivo fue identificar las fuentes de innovación y patrones de interacción en dos sistemas de innovación pecuarios en México con la finalidad de proponer estrategias que permitan mejorar los procesos de aprendizaje e innovación de este tipo de sistemas. A través del estudio de dos sistemas de innovación pecuarios se obtuvieron indicadores de redes sociales que permitieran la identificación de actores y los mecanismos de interacción que siguen en la adopción de innovaciones. Los resultados encontrados muestran que los patrones de interacción responden a la necesidad de innovar y determinan dos tipos de relaciones: una dirigida y la otra liderada por la oportu nidad del mercado. Existen agentes que fungen como intermediarios de la innovación con la capacidad de articular al sistema de innovación, vincular a los actores y llevar la innovación hasta el usuario final. Se concluye que los intermediarios con mayores vínculos definen las fuentes, tipos de innovación y activan los patrones y mecanismos de interacción entre los actores de los sistemas de innovación.

    Alcohol-serving venues in South Africa provide a location for HIV prevention interventions due to risk factors of patrons in these establishments. Understanding the association between mental health and risk behaviors in these settings may inform interventions that address alcohol use and HIV prevention. Participants (n = 738) were surveyed in 6 alcohol-serving venues in Cape Town to assess post-traumatic stress disorder (PTSD) and depression symptoms, traumatic experiences, sexual behavior, and substance use. Logistic regression models examined whether traumatic experiences predicted PTSD and depression. Generalized linear models examined whether substance use, PTSD, and depressive symptoms predicted unprotected sexual intercourse. Men and women were analyzed separately. Participants exhibited high rates of traumatic experiences, PTSD, depression, alcohol consumption, and HIV risk behaviors. For men, PTSD was associated with being hit by a sex partner, physical child abuse, sexual child abuse and HIV diagnosis; depression was associated with being hit by a sex partner, forced sex and physical child abuse. For women, both PTSD and depression were associated with being hit by a sex partner, forced sex, and physical child abuse. Unprotected sexual intercourse was associated with age, frequency and quantity of alcohol use, drug use, and PTSD for men and frequency and quantity of alcohol use, depression, and PTSD for women. Mental health in this setting was poor and was associated with sexual risk behavior. Treating mental health and substance-use problems may aid in reducing HIV infection. Sexual assault prevention and treatment after sexual assault may strengthen HIV prevention efforts.

    Histomorphology as part of morphological research studies bony structure on the tissue level. Its methods are applied in this investigation to evaluate histomorphological impact patterns in heat-exposed bony material, particularly color changes, fissure patterns, volumetric reduction, and changes in the size of Haversian canals. These variables were evaluated in exposed thin sections of porcine long bones, obtained during two experimental series. The first one was conducted under stable thermal conditions in a furnace by measuring heat impact in stepped time (I to S hours) and temperature intervals (200 to 800 C). During a second experimental phase, bony samples were exposed to direct fire in defined time and heat intervals. The treated specimens were then sectioned and microscopically scrutinized. The results presented here were designed to offer new analytical, measurable standards in the investigation of forms of heat exposition of the human body, applicable in forensics and the study of ancient Maya posthumous body treatments.

    Full Text Available Ciertas grandes ciudades llevan a cabo programas de aforestación en un intento de solucionar problemas relacionados con la polución. Esta incorporación de árboles y arbustos ha abierto las puertas a la incorporación de insectos de escama con patrones de distribución y densidad que dependen de múltiples factores. Esta investigación evaluó los patrones de distribución de insectos de escama sobre cuatro especies arbóreas usadas en la aforestación de la zona urbana de Bogotá, Colombia. La presencia y densidad de insectos de escama en árboles georeferenciados fue valorada y variados análisis geoestadísticos fueron realizados para describir su presencia y densidad como función de la distancia entre árboles. En general, los insectos de escama estuvieron distribuidos en áreas con altas densidades. Una distribución no azarosa fue evidente a una escala más detallada, con insectos presentes en pequeños grupos. Sin embargo, se encontraron insectos de escama sobre Ficus soatensis que presentaron una distribución completamente azarosa. El estudio de los patrones de distribución de insectos de escama en condiciones urbanas, en conjunto con estudios complementarios, puede contribuir a entender su respuesta a ambientes multifactoriales y provee datos valiosos para usar en el manejo de plagas.

    Full Text Available El microclima urbano es la resultante de una interacción entre la morfología urbana y el medio ambiente; y su estudio importa porque determina las condiciones de confort térmico en los espacios exteriores a la vivienda y por tanto su uso. Se parte del supuesto que la evaluación energética del entorno urbano no se considera en la actividad proyectual de conjuntos habitacionales. Por ello, el objetivo principal de esta tesis fue investigar el comportamiento energético de tejidos urbanos residenciales contemporáneos, aplicado a dos modelos de habitar: la ciudad jardín y la ciudad de bloque. Se postuló que si a una configuración espacial dada, le corresponde un comportamiento energético singular, entonces sería posible descifrar un patrón morfo-climático. El urbanismo bioclimático enmarca el enfoque teórico de la discusión, y el trabajo de campo se situó en un barrio residencial del pericentro en la metrópolis de Santiago de Chile. El método de caso analizó las dos tipologías de tejidos e integró los parámetros bioclimáticos: temperatura del aire, humedad relativa, radiación solar, y vientos para evaluar su desempeño energético. Los resultados demostraron que el rendimiento energético de los tejidos urbanos variaba según la tipología y con ello fue posible descifrar un patrón bioclimático. Este conocimiento es aplicable a la planificación y al diseño urbano sostenible. Abstract: Urban microclimate is a result of interaction between urban morphology and environment at micro-scale. Its study relevance lies on thermal comfort in outdoor spaces so habitat. It is assumed that energy performance of urban surrounding is not considered at design stage of architectural project. Main purpose of current research was to study energy performance of residential urban fabric applied to two urbanized models: garden city and Corbusier city. Rationale was if spatial configuration influences energy performance then those models would

    Full Text Available Until relatively recently, the task of driving a vehicle was almost exclusively one for men. Only in the last fewdecades have women taken en masse to driving. This review analyses the driving behaviour of men and women andattempts to establish whether women are better or worse drivers than men. It is paradoxical that according to the stereotype,women are less skilful at carrying out manoeuvres such as parking. However, it is said that women are more cautious at thewheel. The statistics show that men tend to be over-represented in traffic accidents although women are said to getdistracted more easily, for example by looking at themselves in mirrors. This study discusses to what extent women’sdriving patterns differ from those of men, how they have changed in recent decades and what the future predicts, taking intoaccount the accident data of these groups. We contrast the popular belief, which portrays women as bad drivers, with datacompiled from the literature on evolutionary and constitutional differences and the differing vulnerability of the twogenders. We analyse whether differences exist in the frequency of driving between men and women, evaluating thecharacteristics, types of journey, accident data and, among other issues, styles of driving: caution vs. aggression at thewheel.

    Full Text Available Sheltered Employment Centers (CEEs are profitable firms that contract workers with disability to prepare them for incorporation in society. Due to their growth, competitiveness in the labor market and work in the framework of the social economy, these companies have attracted some interest recently. However, these enterprises have to face great challenges because they have to be competitive in the market in order to guarantee their survival. The objective of this paper is to analyze the survival of the Sheltered Employment Centers, to ascertain the key variables that condition their continuity in the market, or otherwise, their business failure. The initial sample is the total number of CEEs in Spain, 1.668 firms. The financial statements of all were extracted from 2013, the last period available. Then, the all CEEs were classified in tree groups (healthy, doubtful and distressed, according to their Altman Z’-score. A method of artificial intelligence (algorithm C 4.5 was used in order to obtain the basic patterns of each of the groups. The main contribution of this study is that we can know which CEEs survive with the ratios of debts over net sales, return on assets, and quick ratio and which one will have more difficulties to stay in the market. Moreover, the artificial intelligence methodology used is a new approach compared to traditional statistical techniques.

Por medio de una metodología de observación, se lograron caracterizar patrones de conducta individuales y secuenciales y acciones más complejas de exhibiciones simultáneas. El cabeceo se tomó como el patrón básico de dicho comportamiento, siendo cuantitativamente el más importante.  Se comparó la caracterización de los patrones de conducta agresiva con aquellos presentes en el cortejo, observándose gran similitud con éstos. The territorial aggressive behavior in males of the species Phenacosaurus heterodermus presents a wide range of variation within the individual and among individuals in the patterns of behavior observed. By means of methods of observation it was possible to characterize behavioral patterns of individual and sequence displays, and more complex actions of simultaneous exhibitions. The head bob was taken as the basic pattern for this behavior, being quantitatively the most important.  These aggressive patterns were compared with those present in courtship, of the same species, observing great similarities between them.

  6. Mach-Like Structure in a Patronic-Hadronic Transport Model at RHIC Energies

    International Nuclear Information System (INIS)

    Recent RHIC experimental results indicated an exotic partonic matter may be created in central Au + Au collisions at dollars sqrt (s ( NN))dollars =200 GeV. When a parton with high transverse momentum (jet) passes through the new matter, jet will quench. The lost energy will be redistributed into the medium. Experimentally the soft scattered particles which carry the lost energy have been reconstructed via di-hadron angular correlations of charged particles and a hump structure on away side in di-hadron $ Delta phi$ correlation has been observed in central Au + Au collisions [1,2]. Some interpretations, such as Mach-cone shock wave and gluon Cherenkov-like radiation mechanism etc, have been proposed to explain the splitting behavior of the away side peaks. However, quantitative understanding of the experimental observation has yet to be established. In this work, we use a multi-phase transport (AMPT) model to make a detailed simulation for di-hadron or tri-hadron azimuthal correlation for central Au + Au collisions at dollars sqrt(s ( NN)) dollars =200 GeV. The hump structure on away side (we called Mach-like structure later) in the di-hadron and tri-hadron azimuthal correlations has been observed [3,4,5]. Furthermore, the time evolution of Mach-like structure is presented [6]. With the increasing of the lifetime of partonic matter, Mach-like structure develops by strong parton cascade process. Not only the splitting parameter but also the number of associated hadrons (dollarsN ( h) (assoc)dollars) increases with the lifetime of partonic matter and partonic interaction cross section. Both the explosion of dollarsN ( h) (assoc)dollars following the formation of Mach-like structure and the corresponding results of three-particle correlation support that a partonic Mach-like behavior can be produced by a collective coupling of partons because of the strong parton cascade mechanism. Therefore, the studies about Mach-like structure may give us some critical information

    Full Text Available La familia Arecaceae es rica en especies, principalmente en el trópico, y constituye una fuente de recursos para la subsistencia de sus pobladores. En el presente trabajo se estudió la riqueza, diversidad, composición y patrones de uso de la familia Arecaceae en tres localidades de la cuenca media del río Atrato en el Chocó, Colombia, con el fin de obtener información que permita su conservación y uso sostenible. Se registraron 29 especies en 18 géneros, siendo Bactris 24.13 y Wettinia 10.34 los géneros más ricos en especies. El Buey mostró más especies y géneros 23 especies, 17 géneros que Beté 15 y 10 respectivamente y Tanguí 14 y 11 respectivamente. La similitud florística entre localidades fue menor al 45. Las especies con mayor peso ecológico y valor de uso fueron: Euterpe oleracea Mart., Oenocarpus bataua Mart., Attalea allennii H.E. Moore, Manicaria saccifera Gaertn., Bactris gassipaes Kunth y Wettinia quinaria O.F.Cook y Doyle R. Bernal. Las categorías de uso con mayor riqueza de especies e importancia cultural fueron: construcción, alimento y uso artesanal; y los órganos más usados fueron tallos y frutos. Los resultados de este trabajo demuestran que el Atrato Medio posee alta riqueza y diversidad de especies de palmas en un contexto regional y nacional. Sin embargo, la relación entre el número de uso y la importancia ecológica de la especie depende de la localidad, lo que indica que la importancia socio-cultural de la especie puede variar entre grupos humanos que comparten una misma cultura o región biogeográfica. Se publicarán estudios a futuro para determinar el papel del tipo de órgano utilizado como materia prima en la demografía y dinámica ecológica de las poblaciones de palma en el Chocó y otras regiones del Neotrópico.

    Despite the fact that many US researchers face increasing competition in chasing after federal support that has not kept pace with inflation, the good news is that private support is on the rise. A growing number of wealthy individuals are investing in research areas that reflect their deeply-held passions as their personal philanthropy. They typically are unafraid to take risks, abhor bureaucracy, and nimbly cross disciplinary boundaries. Many put their personal imprimatur on the direction and operation of the ventures that bear their names. However, private funding is not a replacement for federal funding. It is not coordinated. Absent adequate federal support, gaps can develop: between and within fields, in the balance of exploratory, basic, applied, and translational research, and in the support of scientific talent at different levels of training or institutions of different types. The private share remains small and cannot compensate for significant losses in federal dollars. For these reasons, it is important that scientists and philanthropists make the case to our political leadership that private funding does not replace public support. Private funding is and always has been a huge boon to the scientific enterprise. Universities and researchers have for more than a century been successfully merging public and private funds to profit from the advantages of each funding source, accelerate scientific discovery, and benefit humanity. Given the many causes that could engage the attention of these philanthropists, we are fortunate that so many have chosen to give back to society through the geosciences.

    Full Text Available Se realizaron descripciones de la arquitectura foliar, con énfasis en patrones de nerviación, de cuatro géneros y 14 especies de Myrtaceae incluyendo dos especies citadas como exóticas, para la Estación Biológica La Selva, OET, Heredia, Costa Rica. El material fresco descrito fue coleccionado en la estación biológica y fueron visitados los herbarios INB y CR, además de consultar el herbario de la propia estación e imágenes del MO. El 85% de las especies presentan un patrón de nerviación secundaria camptódromo- broquidódromo y ca. 50% poseen nervaduras secundarias rectas, que sólo se curvan cercanas al margen simulando una nervadura intramarginal. Las nervaduras terciarias son detectables a simple vista sólo en siete de las especies, de las cuales cuatro poseen un patrón reticulado y la nerviación última marginal en arcos o no visible. La combinación de los datos de arquitectura foliar con patrones de nerviación permitió discriminar las especies y obtener una clave de determinación de fácil uso en el campo.

    Full Text Available En este trabajo se analiza la representación de los aliens en un grupo reciente de franquicias, comunicaciones periodísticas y transmedia a fin de describir patrones recurrentes y de interpretarlos en el contexto cultural actual. La hipótesis es la preeminencia de la imagen esotérica de los aliens en ellas, como resultado de un hipotexto mitológico fruto de un folk procesado y actualizado en los transmedia. La comunicación mediática sería el canal de difusión de estos neomitos. Para ello, se parte como método del análisis comparativo de diferentes franquicias para detectar patrones narratológicos recurrentes. Las conclusiones conciernen al leitmotiv de las teorías conspiracionistas e interpretaciones milenaristas, ecologistas o neoevemeristas, según su recepción en los distintos grupos. Los símbolos codificados son una hibridación y reactualización de mitos tradicionales, en la dirección esotérica indicada, que proponen nuevas lecturas a cuestiones como el origen de la vida, el medio ambiente o el control de los recursos, configurando así una

  1. The Rise of the Abbasid Public Sphere: The Case of al-Mutanabbī and Three Middle Ranking Patrons

    Directory of Open Access Journals (Sweden)

    Mahdy Ali, Samer

    2008-12-01

    Full Text Available The tenth century in Iraq and Syria saw an unprecedented rise in the number of canonical poets who were delivering glorious praise hymns (madīḥ to middling members of society. Scholars have posed many theories in the past 30 years to explain the function and purpose of praise hymns for royalty and rulers, but why would ordinary men who had no hope of rulership pay painful sums to commission praise hymns in their favor? This article examines the emergence of a new kind of sociability and patronage in the tenth century that enabled middling people to form alliances and exercise influence in shaping ideals of government, leadership and manhood. Examples are given of poems to patrons of middle rank who gain glory and influence via the artistic endorsement of al-Mutanabbī (d. 965: The first ode restores the public dignity of a nineteen-year-old soldier who lost his face in battle; in the second ode, the poet glorifies and defends a state clerk who had little-known Sufi leanings; in the third ode, the poet vindicates an unmasked pseudo- Muslim who was in private a Christian. Using J. Habermas’s theory of the “Public Sphere,” I show the way these odes illustrate how middling members of society gained influence in a public sphere of participation and took measures to preserve that influence.

    En el siglo X, y en la zona de Siria e Iraq, el número de poetas canónicos que dedicaron panegíricos (madīḥ a miembros no destacados de la sociedad experimentó un incremento sin precedentes. A lo largo de los últimos treinta años, especialistas en este campo han formulado diversas teorías sobre los himnos de alabanza dedicados a la realeza y a los gobernantes, pero ¿qué llevó a personas corrientes, sin ninguna aspiración de llegar a gobernar, a pagar grandes cantidades de dinero por himnos de alabanza en su honor? Este artículo plantea la aparición de un nuevo tipo de sociabilidad y un nuevo patronazgo en el siglo X

Con la combinación de mapas de distribución potencial de las especies se creó un mapa de riqueza específica para calcular el porcentaje de celdas ocupadas por el género dentro de cada provincia biogeográfica, de cada RTP y conocer el tipo de uso de suelo. Además, se obtuvo la complementariedad de especies y la ordenación de las RTP a partir de su composición específica. El género se distribuyó en el 80.5% de México, en todas sus provincias biogeográficas. Los estados de Durango, Michoacán, Puebla, Veracruz y Oaxaca presentaron la mayor riqueza específica. Potencialmente, el género puede encontrarse en el 96% de las RTP de México con un patrón altitudinal y climático. De 6 grupos de las RTP, el grupo oriental presentó la mayor riqueza específica. El 25.8% de la distribución potencial del género se encontró en áreas modificadas por el hombre.

    2016-09-01

    Full Text Available Transport innovations have predominantly been recognised for their power to alter geographic space through time space compression. The emergence of Intelligent Transport Systems provides an interesting new lens through which to investigate individuals’ perceptions and constitution of time and space. This paper focuses on one of these systems, the Real Time Passenger Information Signal Pre-emption System (RTPISP System currently being installed in Auckland, New Zealand. It explores how individuals’ travel experiences are being shaped by interface the RTPISP System provides between the ubiquitous computing background and individuals’ everyday lives. This paper proposes that such technologies are causing more than just the compression of space by time. By embedding the mundane activity of catching the bus in the coded spaces of the RTPISP System new conditions of possibility are emerging allowing these bus patrons to constitute alternative timespaces while waiting for the bus, timespaces which they previously were unable or unwilling to access.

    Full Text Available Después de identificar nuevas fuentes de resistencia a la roya, causada por Uromyces appendiculatus, es necesario saber si las variedades con nuevos genes conservarán su resistencia cuando sean sembradas en diferentes regiones de producción. Para ello, se pueden utilizar viveros móviles con líneas/variedades de frijol con diferentes genes de resistencia para obtener los patrones de virulencia del patógeno de la roya. El vivero contiene plantas de frijol con seis días después de la germinación. El vivero se coloca por dos a tres horas en un campo de frijol infectado con la roya, y luego se exponen a las plantas bajo neblina por un periodo de 15 horas dentro de un ambiente controlado, para un un período de incubación de ocho a diez días en una casa de malla.

    Full Text Available El efecto de la variación ambiental en la estructura de las comunidades arbóreas en bosques tropicales, aún se debate. En paisajes como los bosques de tierra firme, donde el gradiente ambiental disminuye, el efecto de los suelos sobre los patrones de distribución de especies es mínimo. En contraste, un mayor efecto de la variación edáfica y topográfica sobre la composición florística, se ha reportado en estudios con diferentes tipos de plantas en bosques tropicales. Este estudio se realizó en diez hectáreas de una parcela permanente. Se evaluó el efecto de la variación ambiental y la configuración espacial sobre los patrones florísticos de las especies arbóreas a escala local, según el estado de desarrollo y categorías de abundancia relativa. Se registraron 14 074 individuos de 1 053 especies y 80 familias. Los suelos son ácidos, presentan altas concentraciones de Aluminio y son predominantemente arcillosos. La diversidad beta fue baja. Las diferencias florísticas explicadas fueron asociadas con procesos biológicos espacialmente estructurados, particularmente, con la limitación en dispersión. Aunque, la mayor parte de la variación no fue explicada por las variables consideradas. Estos resultados sugieren que procesos aleatorios son determinantes esenciales de la variación florística en bosques de tierra firme de la amazonia.

    En el Centro Nacional de Investigaciones del ICA, Palmira, se estudió el sistema de raíces de 12 patrones injertados con naranja Frost Valencia, de 14 años de edad, sembrados en un suelo Franco-Arcilloso. Se tomaron muestras a 1.0, 1,5, 2.0 y 3.0 m de distancia de la base del árbol y a profundidades de 0-20, 20-40, 40-60, 60-80 Y 80-100 cm, considerando cada distancia. Los patrones que mostraron la mayor densidad de raíces fueron: Amblycarpa, Citrange Carrizo y Mandarina Cleopatra. Se encontró correlación directa y altamente significativa entre el sistema de raíces menores de 2 mm de diámetro con la altura y diámetro del árbol, lo mismo que con el volumen de la copa. Estos aspectos son de especial importancia para evaluar el grado de adaptación a diferentes condiciones de suelo, al momento de plantar un huerto.

    At the ICA National Research Center in Palmira a study of the root system of 12 rootstocks grafted with "Frost Valencia" orange 14 years old grown on clay-loam soil was conducted. Root samples were taken at distances of 1.0, 1.5, 2.0 and 3.0 m from stem and a depth of 0-20, 20-40, 40-60, 60-80 and 80-100 cm in each distances. The rootstocks Amblycarpa, Citrange Carrizo and Cleopatra Mandarin presented the greater root densities. The height, diameter and the foliage tree volume showed positive correlation whit a diameter lesser than two millimeter. That's special importance for the adaptation several soil's conditions.

    Full Text Available We studied the phenological patterns and the reproductive success of 103 Ceiba pentandra trees, located in the tropical dry and wet forests of the Pacific coast of Costa Rica. To determine the phenological patterns of this species we recorded leaf fall, flower and fruit production of marked trees every two-weeks from December through March over three years (2001, 2002 and 2003. We also recorded the flowering and fruiting frequencies for two more years (2000 and 2004. Our data suggest that phenological patterns of C. pentandra trees behave as irregular cycles rather than cycles fixed at supra-annual intervals, and the forest type in which the trees are located does not have a decisive effect on either the probability or the frequency of the reproductive cycles. The absence of a pattern of negative autocorrelations in qualitative reproductive success (e.g., no reproduction, only flowers and fruits among successive years suggests that the flowering or fruiting cycles of this species do not correspond to a simple model of resource limitation. Our results show that there is no relationship between the reproductive success and the periodicity of the reproductive cycles in this species.Estudiamos los patrones fenológicos y el éxito reproductivo de 103 árboles de Ceiba pentandra, localizados en el bosque tropical seco y en el bosque tropical húmedo de la costa del Pacífico de Costa Rica. Para determinar los patrones fenológicos se anotó la caída de hojas y la producción de flores y frutos cada dos semanas desde diciembre hasta marzo para todos los árboles marcados por un periodo de tres años (2001, 2002 y 2003. También se tomaron datos de la frecuencia de floración y fructificación para dos años más (2000 y 2004. Nuestros datos sugieren que los patrones fenológicos de árboles de C. pentandra se comportan como ciclos irregulares más que como ciclos fijos de intervalos supraanuales y el tipo de bosque en el cual los árboles se ubican

    Full Text Available En el presente trabajo se analizaron los patrones de diversidad alfa en tres áreas protegidas de bosque con base en información florística proveniente de seis parcelas permanentes de 1ha -dos en cada área protegida-. Las regiones de estudio están localizadas a lo largo de un gradiente altitudinal, en la parte norte de la cordillera central de los Andes, Colombia. Para los análisis, se generaron dos categorías de acuerdo al tamaño de los árboles: dosel (diámetro a la altura del pecho mayor o igual a 10cm y sotobosque (diámetro a la altura del pecho mayor o igual a un cm y menor a 10cm. Las curvas especies-área mostraron diferencias en riqueza para las dos categorías de tamaño en las tres regiones. Las curvas especies-individuos, en cambio, fueron independientes con respecto al tamaño de los individuos, excepto en la región de Belmira. La diversidad, medida con el índice alfa de Fisher, mostró una fuerte tendencia a la estabilización en muestras mayores a 1 000 individuos. Ni las curvas de especies-área ni las de especies-individuos fueron asintóticas; sin embargo, la tasa de acumulación de especies (z en Belmira alcanzó valores muy bajos (0.05 en comparación con Anorí y Angelópolis (0.25 en cada caso. El índice alfa de Fisher permitió además entender la magnitud de las diferencias relativas en diversidad entre regiones o tipos de bosque en gradientes altitudinales, aun cuando el tamaño de la muestra fue relativamente pequeño. Los resultados de este estudio soportan la limitación en dispersión como el principal mecanismo en estructurar las comunidades de especies a escalas muy finas, y un incremento continuo de procesos denso-dependientes en determinar la estructura de la comunidad en escalas espaciales más grandes. Igualmente, los resultados de este estudio proponen que la denso-dependencia tiende a aumentar positivamente con la altitud.Alpha diversity patterns in three fragmented forests of Northern Andes

    Full Text Available OBJETIVO: Describir el patrón de uso de servicios generales y especializados entre los adultos con problemas de salud mental, así como su nivel de satisfacción con dichos servicios, con la finalidad de contribuir a optimizar los escasos recursos disponibles en la Región para la atención de la salud mental, particularmente en lo que corresponde a Chile. MÉTODO: Los diagnósticos y los patrones de uso de los servicios de salud mental se obtuvieron del Estudio Chileno de Prevalencia Psiquiátrica (ECPP, una investigación representativa de la población adulta del país, basada en una muestra aleatoria estratificada de 2 987 personas de 15 años y más, que abarcó el período de 1992 a 1999. Los diagnósticos psiquiátricos se obtuvieron por medio del instrumento de entrevista denominado Composite International Diagnostic Interview (CIDI. Asimismo, se preguntó a los entrevistados acerca del uso de servicios generales y de salud mental en los seis meses precedentes y sobre las dificultades que encontraron para acceder a ellos. RESULTADOS: Más de 44% de los entrevistados tuvieron contacto con algún tipo de servicio de salud durante los 6 meses previos al estudio, pero solo 5,6% recibieron atención especializada. Quienes presentan los diagnósticos de trastorno obsesivo y de pánico consultan con mayor frecuencia, pero no en centros especializados. El consumo de sustancias tóxicas y la personalidad antisocial se relacionaron con un bajo nivel de consulta. El sistema formal de salud es la opción que más se menciona como recurso de ayuda. Más de 75% refieren satisfacción o gran satisfacción con la atención recibida. CONCLUSIONES: Se confirma la existencia de una amplia brecha entre las necesidades de atención y el tratamiento realmente recibido. Los recursos alternativos informales y folclóricos (sacerdote, familiares, curanderos, hierbateros [yerberos], etc. se utilizan con una frecuencia menor de la esperada. Las barreras

    Full Text Available Para utilizar en forma confiable información obtenida con tecnología satelital, es necesario eliminar o disminuir los efectos perturbadores que se asocian con la información espectral que captan los sensores a bordo de las plataformas espaciales. En el presente trabajo se analiza la inversión de los modelos de radiación de la atmósfera, que consiste en determinar las constantes aditivas y multiplicativas por banda espectral, para realizar las correcciones atmosféricas necesarias. La metodología propone el uso de los patrones invariantes de las líneas del suelo y la vegetación densa, para la inversión de los modelos de radiación. Los resultados mostraron que, sin conocimiento del modelo atmosférico ni del tipo de aerosol, con el uso de datos de la línea del suelo fueron relativamente pobres (correlación baja para la obtención de las constantes aditivas y multiplicativas de las inversiones atmosféricas, con problemas de soluciones múltiples en el proceso de inversión. Bajo condiciones similares, ocurrió lo mismo para las constantes aditivas con la línea de la vegetación densa, pero para las constantes multiplicativas, los resultados fueron favorables (R2 > 0.9. A diferencia de lo anterior, con conocimiento del modelo atmosférico y del aerosol, las estimaciones de las constantes aditivas y multiplicativas resultaron altamente satisfactorias (R2 > 0.99 en ambos casos. Para las inversiones de la línea del suelo sólo se usó una restricción de las dos disponibles. En conclusión, el uso de los patrones invariantes de las líneas del suelo permite establecer dos relaciones básicas para invertir las simulaciones de modelos de radiación de la atmósfera, previa compactación funcional, y se puede recurrir a mediciones en campo para que el proceso de corrección atmosférica propuesto en el presente trabajo pueda considerarse en términos absolutos y no relativos.

    Full Text Available Resumen Antecedentes y Objetivo: En la Cirugía Plástica es fundamental una adecuada planificación preoperatoria y un conocimiento de la variabilidad anatómica de los vasos perforantes de la mama, que junto con las modificaciones provocadas por cirugías previas, hacen que el disponer de un sistema fiable de localización preoperatoria de los vasos sea de enorme utilidad para elegir la mejor técnica quirúrgica a utilizar. El objetivo del presente trabajo es determinar si la mamografía 3D/tomosíntesis es el método de elección para visualizar el patrón vascular del complejo areola-pezón (CAP en cirugía mamaria secundaria: mamoplastia de aumento, reductora y mastopexia con o sin implantes, para evitar complicaciones desde el punto de vista de su irrigación y elegir así la mejor vía de acceso para la cirugía secundaria. Material y Método: Llevamos a cabo un estudio clínico prospectivo, longitudinal y descriptivo sobre una muestra de 31 pacientes, todas mujeres sanas con antecedente de cirugía mamaria previa, a quienes se les realizó mamografía en 3 dimensiones (tomosíntesis para determinar su patrón vascular mamario. Resultados: Los patrones vasculares dominantes fueron los superiores (58.06%, las cicatrices encontradas fueron principalmente periareolares (48.3% y las cirugías secundarias realizadas, dependiendo de los patrones vasculares recogidos en la tomosíntesis, fueron pedículos superiores (87%. Las cicatrices no indicaron el tipo de patrón vascular usado en la cirugía previa. No encontramos ningún caso de necrosis del CAP. Conclusiones: El uso de la tomosíntesis como método de imagen en la evaluación preoperatoria de la vascularización en mamoplastias de revisión representa una herramienta útil para planificar la técnica quirúrgica a realizar en vista de que ofrece una información real y exacta, lo que conlleva evitar complicaciones vasculares como necrosis del CAP, garantizando una cirugía segura y

    Full Text Available Este trabajo aborda el problema del consumo de agua y energía en la minería sudamericana desde una arista menos explorada: el consumo sustentable. A partir de la sociología y los estudios sociales de la ciencia y la tecnología exponemos esta problemática presentando tres patrones de consumo distintos: convencional, alternativo y progresista. A partir de fuentes secundarias y entrevistas semi-estructuradas hemos rastreado las controversias en torno a dos proyectos mineros históricos argentinos: La Alumbrera y Cerro Vanguardia, focalizando nuestras interrogantes en torno al consumo sustentable de recursos vitales como el agua y la energía. Hemos podido constatar cuán urgente se interpreta la necesidad de transitar hacia patrones de consumo sustentable, quiénes son los llamados a emprenderlos y cuáles precisiones serían necesarias a distintas escalas para efectuar dicha transición. Reconociendo que el agua y la energía son factores constitutivos del tránsito hacia patrones de consumo sustentable en minería, planteamos su centralidad en la gestión de conflictos locales dentro de la gobernanza ambiental latinoamericana. Este estudio forma parte de uno más amplio que abarca varios países sudamericanos.

    Full Text Available El proyecto de las escuelas federales Artículo 123 aporta una mirada a los procesos de federalización centralizadora del Estado mexicano posrevolucionario; ofrece además un caso para el análisis de los supuestos acerca del radicalismo cardenista y el viraje de las políticas del Estado en la transición al gobierno de Ávila Camacho. El caso de estas escuelas pone de manifiesto la incapacidad del Estado para implementar sus políticas y la capacidad del poder patronal para resistir a los mandatos del Estado desde las trincheras jurídicas. La perspectiva del estado en la sociedad de Migdal ofrece valiosos elementos para entender al Estado no sólo como una representación idealizada, sino como un ente complejo y contradictorio que interactúa constantemente con otros poderes. Desde el ámbito de la historia de la educación, el artículo ofrece un análisis del enfrentamiento jurídico suscitado entre el poder patronal y el Estado mexicano en torno de las escuelas Artículo 123, a partir de la propuesta y aprobación de leyes, la argumentación jurídica esgrimida como defensa patronal, y los fallos y jurisprudencias emitidos por la Suprema Corte de Justicia de la Nación.

    Full Text Available Los más recientes cambios en los patrones de migración interna en varios países de Latinoamérica, apuntan a los crecientes flujos de migración intrametropolitana desde los centros urbanos hacia la periferia, asociados a procesos de urbanización residencial de zonas rurales cercanas a la zona metropolitana. Este artículo analiza este fenómeno para Costa Rica, estimando los patrones de migración interna dentro del Gran Área Metropolitana (GAM, y tratando de determinar algunos factores de atracción y expulsión que posiblemente explican estos patrones, utilizando un modelo de Poisson para discriminar entre algunas variables seleccionadas en un modelo de regresión multivariable. Los resultados confirman algunas tendencias observadas para otras áreas metropolitanas de América Latina, y da algunas explicaciones al caso específico de la GAM.

    Full Text Available Se busca encontrar patrones espaciales de agrupación de la criminalidad entre jóvenes y población total en Medellín, Colombia, durante el período comprendido entre octubre del 2013 y noviembre del 2014. Para esto se creó una malla hexagonal de ciudad y buscamos clústeres de agrupamiento entre trece variables delictuales. Para encontrar los clústeres usamos las técnicas de substractive clustering y fuzzy c-means clustering. Al correr los clústeres encontramos microcorredores territoriales donde la criminalidad alta se consolida durante varios períodos de tiempo y patrones temporales que muestran cómo algunas zonas de alta criminalidad se van formando de modo gradual. Adicionalmente, se buscaron patrones espaciales de criminalidad entre jóvenes, y se encontró que este grupo etario suele presentar mayor variabilidad en la dinámica criminal y territorios de injerencia más pequeños que el resto de la población.

    Full Text Available OBJETIVO: Describir la prevalencia del consumo de heroína, los patrones de inicio, el alto consumo y la dependencia a esta sustancia e identificar barreras que impidan a los adictos acudir a tratamiento. MATERIAL Y MÉTODOS: El estudio se realizó en la cárcel de Ciudad Juárez, Chihuahua, México, entre abril y junio de 2000; los participantes se obtuvieron a través de un muestreo aleatorio simple, partiendo del censo del penal. Se identificaron las barreras al tratamiento, estimadas mediante un modelo de regresión logística. RESULTADOS: La prevalencia de consumo de heroína en los últimos seis meses fue de 26.4%; de 25.3% para usuarios fuertes; 95% fueron dependientes. El promedio de la edad de inicio del consumo fue a los 21 años. El modelo multivariado mostró que baja escolaridad, abstinencia, sobredosis, enfermedades crónicas y tiempo de exposición son barreras que impiden solicitar tratamiento. CONCLUSIONES: Las implicaciones de los resultados se discuten en función de aplicarlos para implantar programas de tratamiento en las cárceles.

    Full Text Available La Sierra Norte de Puebla (SNP es una región con gran diversidad biológica y cultural en donde la cafeticultura ha tenido un papel relevante en el uso del suelo. El objetivo de esta investigación es conocer los patrones espaciales de la dinámica de cambio de la cobertura vegetal y el uso del suelo entre 1988-2003, y relacionarlos con las actividades de cafeticultura en la SNP. El análisis de cambio se realizó mediante una clasificación supervisada de dos imágenes de satélite Landsat, y se evaluó el cambio espacial entre las dos fechas mediante una matriz de detección de cambios. En ella se encontró que en el 58.4% del área no hubo cambios y en el 41.6% sí los hubo. Los principales tipos de cambio fueron de pastizal (cultivado e inducido o agricultura anual a cafetales con sombra/vegetación secundaria intermedia de bosque tropical o bosque mesófilo de montaña/cultivo permanente de cítricos; asimismo, el proceso de cambio de cobertura y uso del suelo está relacionado con la problemática actual del café.

Entre los hallazgos más destacables, se encuentra la correspondencia con las tendencias de la segregación residencial en otras ciudades latinoamericanas: una mayor segregación a escala menor y una disminución en el tiempo de los niveles de la segregación. Asimismo, la Gran Área Metropolitana (GAM en general presenta menores índices de segregación que varias ciudades latinoamericanas, particularmente Santiago de Chile, diferencia que se explica por el origen y la estructuración histórica de la ciudad, pues la GAM se caracteriza por ser un espacio urbano menos polarizado, más heterogéneo, con una concentración de las élites en áreas pequeñas distribuidas por toda la ciudad y una distribución más bien dispersa de una amplia clase media.

    Full Text Available La reciente investigación antropológica y sociodemográfica sobre los significados de la sexualidad entre la población mexicana reporta la existencia de un patrón de iniciación sexual diferenciado para hombres y mujeres marcado por el género. Por lo general para los varones la primera relación sexual tiene un carácter ritual, y es llevada a cabo bajo la presión del grupo de pares, ante el cual los jóvenes deben dar prueba de su identidad masculina. En contraste, las mujeres deben mantener una actitud de recato y preservar su virginidad hasta el matrimonio. La iniciación sexual femenina, a diferencia de la masculina, por lo general implica el establecimiento de vínculos emocionales así como el inicio de la inda conyugal y reproductiva. Teniendo en cuenta estos hallazgos, exploramos los datos de la Encuesta Nacional de Salud Reproductiva (Ensar de 2003 para comparar, desde una perspectiva de género, las experiencias de hombres y mujeres de distintas generaciones y grupos sociales. Intentamos detectar los cambios en el tiempo e identificar diversos patrones de iniciación sexual por grupos sociales.

    To collect data on tobacco brand visibility on packaging on outdoor tables at bars/cafes in a downtown area, prior to a proposed plain packaging law. The study was conducted in the Central Business District of Wellington City in March 2014. Observational data were systematically collected on tobacco packaging visibility and smoking by patrons at 55 bars/cafes with outdoor tables. A total of 19,189 patrons, 1707 tobacco packs and 1357 active smokers were observed. One tobacco pack was visible per 11.0 patrons and the active smoking prevalence was 7.1% (95%CI: 4.9-9.2%), similar to Australian results (8.3%). Eighty percent of packs were positioned face-up (showing the brand), 8% face-down (showing the large pictorial warning), and 12% in other positions. Pack visibility per patron was significantly greater in areas without child patrons (RR=3.1, pmarketing. The results also provide baseline data for the future evaluation of plain packaging if a proposed law is implemented in New Zealand. Other results warrant further research, particularly the reasons for lower pack visibility and smoking when children were present.

MATERIAL Y MÉTODOS: El estudio se realizó en la cárcel de Ciudad Juárez, Chihuahua, México, entre abril y junio de 2000; los participantes se obtuvieron a través de un muestreo aleatorio simple, partiendo del censo del penal. Se identificaron las barreras al tratamiento, estimadas mediante un modelo de regresión logística. RESULTADOS: La prevalencia de consumo de heroína en los últimos seis meses fue de 26.4%; de 25.3% para usuarios fuertes; 95% fueron dependientes. El promedio de la edad de inicio del consumo fue a los 21 años. El modelo multivariado mostró que baja escolaridad, abstinencia, sobredosis, enfermedades crónicas y tiempo de exposición son barreras que impiden solicitar tratamiento. CONCLUSIONES: Las implicaciones de los resultados se discuten en función de aplicarlos para implantar programas de tratamiento en las cárceles.OBJECTIVE: To assess the prevalence of heroin use, patterns of initiation, intense use, and drug-dependency; also, to assess barriers to drug treatment access. MATERIAL AND METHODS: The study was conducted in the Ciudad Juarez, Chihuahua prison. Subjects were selected using simple random sampling from census of prison inmates. Barriers to drug treatment were identified and analyzed using a logistic regression model. RESULTS: The prevalence of heroin use for the last six months was 26.4%; 25.3% were intense heroin users; and 95% showed dependence. The mean age of initiation was 21 years. A multivariate model showed that the significant barriers to drug treatment access were: low education, withdrawal, overdosing, presence of chronic diseases, and duration of heroin use. CONCLUSIONS: Study findings should serve to devise potential applications to establish treatment programs in prisons.

    In this observational study, we determined how frequently consumers accessed on-premises nutrition information provided at chain restaurants. The number of patrons entering and accessing nutrition information was recorded at 8 locations that were part of 4 major restaurant chains (McDonald's, Burger King, Starbucks, and Au Bon Pain). Only 6 (0.1%) of 4311 patrons accessed on-premises nutrition information before purchasing food. This very small percentage suggests that such information should be more prominently displayed, such as on restaurant menu boards, to help customers make informed decisions.

El patrón delictivo es el conjunto de características que tienen en común varios incidentes con relación a las víctimas, los perpetradores y el modus operandi. Las pruebas y los análisis con base en patrones han sido utilizados con éxito principalmente en las investigaciones de masacres, destrucciones y desplazamiento, pero su utilización en imputaciones de violencia sexual ha sido notoriamente más limitada.

The study area comprises two biogeographical regions (eurosiberian and mediterranean, and 3000 meters of altitudinal range (from 400 to 3400. A total of 2620 taxa have been recorded (103 endemics of the Pyrenees, 10 located exclusively in the study area from 150000 records of presence/ absence. They represent a third of the Iberian flora in just 3% of the spanish iberian territory. Of them, 6.5% are rare, and 7% are aliens. Grasslands, in particular those above the timberline, are the richest habitats in terms of number of species. Wetlands and tall herb fringe communities, as well as cliffs and screes, however, stand out when taking into account the extension of habitats. More than half of the plants can be found between 1000-1300 m.a.s.l., and only 17% in very well preserved habitats. These later ones shelter plants of highest interest from a taxonomic, biogeographic, and conservation point of view. Protected areas constitute 34% of the studied territory, and contain more than 90% of the flora, endemisms, and rare plants, as well as 80% of the localities of endangered species. Surprisingly, however, only 22% of “rare” plants are also catalogued as “endangered”, suggesting that the Regional Catalogue of Endangered species should be reviewed.

    2009-01-01

    From the 15th century to the present day, Christian art has portrayed people who suffer from epilepsy as attributes in illustrations of Saint Valentine (SV). The objective of our study was to interpret the works of art from a modern epileptological perspective on the basis of a collection of portrayals of SV in Europe that was as comprehensive as possible. The people depicted as attributes were analyzed with respect to their age, gender, social status, and possible seizure semiology. Three hundred forty-one illustrations of SV from Austria, Belgium, Croatia, Czech Republic, France, Germany, Hungary, Ireland, Italy, Luxembourg, Poland, Scotland, Slovakia, and Switzerland were systematically analyzed. Irrespective of the age of the work of art, among the 143 pictures of people with possible epilepsy characteristics, there were more males than females from various levels of society. As far as could be interpreted, there were 17 infants, 35 children, 7 adolescents, and 84 adults. With respect to possible seizure semiology, infantile spasms (n=10), atonic seizures (n=13), tonic seizures (n=53), absences (n=2), psychogenic seizures (n=4), and postictal or undefinable states (n=61) were differentiated in a subjective assessment. Despite the fact that from a modern perspective, the 15th to 20th centuries in Europe seemed to be dominated by a rather superstitious attitude toward epilepsy, there is striking accuracy in the detail of the semiology in many of the historic portrayals, and a well-founded knowledge of epilepsy is apparent.

    We present a synthetic view of continental-shelf evolutionary patterns around the Iberian Peninsula, focusing on proposed sequence stratigraphy interpretations and attempting a comparison between Atlantic- and Mediterranean-type shelf-margin constructions. Most of the studied shelves show a dominance of regressive to low stand deposition through successive pro gradations, particularly evident in the Pliocene-Quaternary, documenting the influence of glacio-eustasy. Transgressive to high stand development predating the Last Glacial Maximum seems to be favoured off major rivers, but the highest variability is seen during post glacial evolution. Transgressive deposits tend to show a higher spatial variability, ranging from pro graded para sequences to extensive sand sheets. Holocene high- stand deposits usually show a more homogeneous character, with development of proximal wedge-shaped deposits and a distal sheet-like deposition. Atlantic continental shelves off Iberia display three different types of shelf growth: depositional shelves, shelves with restricted pro gradation and erosional shelves. They result from the interplay between depositional and hydrodynamic regimes, with the occurrence of a latitudinal gradation from erosional shelves in the Cantabrian continental shelf to depositional shelves in the northern Gulf of Cadiz shelf. Some shelf sectors do not correspond to this general pattern, as shelf sedimentation is mainly controlled by morpho-structural features (e.g., ria environments and shelves crossed by major tectonic accidents). The Mediterranean continental shelves of Iberia show two basic types, high- versus low-supply shelves, and their growth patterns are mainly a response to the amount of fluvial supply. The low-supply style is clearly the most frequent type, and it may show further complexity according to the occurrence of submarine canyons and/or morpho-structural control. (Author)

  14. Of the Helmholtz Club, South-Californian seedbed for visual and cognitive neuroscience, and its patron Francis Crick.

    2014-03-01

    Taking up the view that semi-institutional gatherings such as clubs, societies, research schools, have been instrumental in creating sheltered spaces from which many a 20th-century project-driven interdisciplinary research programme could develop and become established within the institutions of science, the paper explores the history of one such gathering from its inception in the early 1980s into the 2000s, the Helmholtz Club, which brought together scientists from such various research fields as neuroanatomy, neurophysiology, psychophysics, computer science and engineering, who all had an interest in the study of the visual system and of higher cognitive functions relying on visual perception such as visual consciousness. It argues that British molecular biologist turned South Californian neuroscientist Francis Crick had an early and lasting influence over the Helmholtz Club of which he was a founding pillar, and that from its inception, the club served as a constitutive element in his long-term plans for a neuroscience of vision and of cognition. Further, it argues that in this role, the Helmholtz Club served many purposes, the primary of which was to be a social forum for interdisciplinary discussion, where 'discussion' was not mere talk but was imbued with an epistemic value and as such, carefully cultivated. Finally, it questions what counts as 'doing science' and in turn, definitions of success and failure-and provides some material evidence towards re-appraising the successfulness of Crick's contribution to the neurosciences.

    Full Text Available En la literatura histórica colombiana y caribeña se ha dado un fuerte acento en el papel que jugaron las ciudades y las regiones que emergieron de ellas en ola formación la moderna cultura caribeña. En la arqueología el énfasis se ha limitado a analizar procesos prehispánicos adaptativos a condiciones cambiantes del medio ambiente dejando de manera tacita fuera de foco la discusión de las consecuencias sociales y culturales de la conquista y la colonia y su impacto en el tejido social que surgiría a finales del siglo XVI. Estas delimitaciones disciplinarias se han convertido en un obstáculo para el conocimiento e interpretación de las dinámicas que siguieron al impulso inicial de la colonización del litoral caribeño y la bien conocida fundación de los centros militares y administrativos. Consecuentemente los historiadores han ignorado en gran parte el papel de las poblaciones aborígenes en la formación de los asentamientos al interior de la llanura costera a pesar que es un hecho bien conocido que no desaparecieron completamente después del siglo XVI. A pesar de que han existido intentos de sintetizar y complementar la información histórica con datos arqueológicos especialmente en los últimos diez años no hemos asistido a un evaluación del campo que consideramos de la mayor importancia para entender la estrategias a traves de las cuales las comunidades aborígenes y algo mas tarde las comunidades de composición mixta africano-indígena y mestizas establecieron exitosamente una serie de asentamientos fuera del sistema colonial reinante. El análisis de los patrones de asentamiento se ha restringido a estudios arqueológicos pero su potencial se extiende mucho mas alla de esta disciplina.

    Full Text Available Introducción. La esquizofrenia altera la percepción del individuo, el pensamiento, el afecto y el comportamiento. El tratamiento farmacológico puede mejorar estas manifestaciones. Objetivo. Determinar los patrones de prescripción de medicamentos antipsicóticos en un grupo de pacientes afilados al Sistema General de Seguridad Social en Salud de Colombia. Materiales y métodos. Se llevó a cabo un estudio descriptivo sobre base de datos de 6,2 millones de personas. Se seleccionaron los pacientes medicados con antipsicóticos, de ambos sexos, todas las edades, con tratamiento continuo de marzo a junio de 2012, y residentes de 57 ciudades colombianas. Se diseñó una base de datos sobre consumo de medicamentos, obtenidos por la empresa que dispensa dichos fármacos. Resultados. Se estudiaron 3.075 pacientes con edad promedio de 55,8±21,5 años; 50,3 % eran mujeres; 81,9 % recibían monoterapia y, 18,1 %, dos o más antipsicóticos. El orden de prescripción fue: atípicos, 77,1 %, y clásicos, 31,9 %. Los medicamentos más utilizados fueron: quetiapina (30,3 %, clozapina (23,7 %, levomepropamiza (18,4 % y risperidona (14,9 %. Las combinaciones más frecuentes fueron: haloperidol más levomepromazina (n=67; 12,1 % de las asociaciones, clozapina más pipotiazina (n=54;9,7 % clozapina más risperidona (n=45; 8,1 %, quetiapina más levomepromazina (n=40; 7,2 %. Los medicamentos prescritos concomitantemente más frecuentes fueron: antidepresivos (n=998; 32,5%; ansiolíticos (n=799; 26,0 %; hipolipemiantes (n=672; 21,9 %; antiparkinsonianos (341; 11,1 % yantidiabéticos (n=327; 10,6 %. Conclusiones. Predominan los hábitos de prescripción de medicamentos de alto valor terapéutico, principalmente en la monoterapia antipsicótica. En la mayoría, se emplean en dosis superiores a las recomendadas. Se plantea la necesidad de diseñar estrategias educativas para corregir algunos hábitos de prescripción e investigaciones que evalúen la efectividad

    Full Text Available Resumen: En este trabajo se presenta una metodología para el reconocimiento en-línea de acciones humanas en secuencias de vídeo. Se aborda un enfoque eficiente para el uso de momentos invariantes como descriptores de imagen, aplicados en siluetas obtenidas del procesamiento de mapas de profundidad. Una comparación rápida entre ventanas de tamaño 4 (equivalente a 4 frames es realizada mediante el cómputo de la distancia de Mahalanobis, sobre una de las secuencias de momentos invariantes identificada como la menos sensible al ruido de captura y la más estable durante ausencia de movimiento. Este enfoque es usado para la detección rápida del estado de parada/movimiento, el cual permite la captura de intervalos (ventanas de crecimiento dinámico para su posterior procesamiento, rescatando de la señal contenida sus propiedades temporales y frecuenciales. Mediante la aplicación de la transformada Wavelet Haar, tres niveles de descomposición son utilizados para el cómputo de la Energía Relativa Wavelet (RWE - Relative Wavelet Energy y SSC (Slope Sign Change, obteniendo patrones 11-dimensionales. En experimentos realizados, el 97% de 4 movimientos capturados en-línea fueron reconocidos correctamente, y 10 movimientos tomados de la base de datos Muhavi-MAS fueron reconocidos con 94,2% de efectividad. Abstract: This paper presents a methodology for online human action recognition on video sequences. It addresses an efficient approach to use invariant moments as image descriptors, applied in processing silhouettes obtained from depth maps. A quick comparison between size-4 windows (equivalent to 4 frames is performed by computing the Mahalanobis distance, on one of the invariant moment sequences identified as less sensitive to noise and more stable during movement absence. This approach is used for rapid detection of the idle/motion state, which allows the capture of dynamic growth intervals (windows for further processing, rescuing from

    Full Text Available We observed behavioral patterns of territorial male guanacos (Lama guanicoe in Torres del Paine National Park, Chile. Both solo territorial males and family-group territorial males were observed to compare the activity time budgets of males (n = 23 in different social groups and habitats. We found no difference in the activity time budgets of males based on social group type, total number of females or all guanacos present, or age of territorial males. Males, in all categories, spent most of their time foraging (65 % of overall time budget. There was a significant difference in time spent in aggressive and in miscellaneous (defecation, alertness to observer, scratching activities based on habitat type; most aggressive encounters and miscellaneous activity occurred on hilltops of areas dominated by mata barrosa shrubs (Mulinum spinosum. It is likely that territorial male guanaco behaviors are related to the resources defended rather than to any direct ability to attract potential mates.Observamos patrones de comportamiento de guanacos machos territoriales (Lama guanicoe en el Parque Nacional Torres del Paine, Chile. Comparamos el presupuesto de actividad de machos solos y en grupos familiares (n = 23 en diferentes hábitat. No encontramos diferencias en los presupuestos de actividad de machos basados en el tipo de grupo social, número total de hembras o número total de guanacos presentes, o la edad de los machos territoriales. Guanacos macho en todas las categorías asignaron alrededor de 65 % de su actividad a forrajeo. Por otra parte, detectamos una influencia del tipo de hábitat sobre el tiempo asignado a interacciones agresivas y misceláneas (defecación, vigilancia al observador, rasguñando; las interacciones agresivas y conductas misceláneas fueron más frecuentes en cimas de colinas de áreas dominadas por el arbusto mata barrosa (Mulinum spinosum.

    ía esperar, reflejos en otros niveles, en particular en el contexto del matrimonio. Contrariando la tendencia decreciente, observada para el total de matrimonios producidos entre 2001 y 2009, aquellos en que por lo menos uno de los cónyuges nació en Brasil casi se cuadruplicaron en ese período. Para muchos autores, los matrimonios mixtos son un buen indicador de la integración de las comunidades inmigrantes en la sociedad de acogida. Así pues, dada la importancia de la comunidad brasileña residente en Portugal, es relevante observar cuál es el peso de los matrimonios mixtos en esta comunidad y analizar sus patrones de matrimonio. El análisis estadístico de los microdatos de los matrimonios, puestos a nuestra disposición por el Instituto Nacional de Estadística, posibilitó estudiar y caracterizar la evolución de los matrimonios registrados en Portugal, entre 2001 y 2009, involucrando a brasileños residentes en Portugal. Quedó patente la existencia de un elevado nivel de matrimonios mixtos, en especial con portugueses, durante este período, lo que indicia su integración en la comunidad de acogida. Se verificaron igualmente algunas diferencias en los patrones de matrimonio entre los sexos, así como una tendencia a la disminución de la importancia de los matrimonios mixtos, en especial entre los hombres.Over the past decades, the number of foreign residents in Portugal has increased significantly. In this context, the Brazilian community is of increasing importance, and was, in 2009, the most represented nationality, with a 25% share in the total of foreign residents in Portugal. As expected, this development reflects on other levels, particularly in the context of marriage. Contrary to the downward trend observed for total marriages occurring between 2001 and 2009, those in which at least one spouse was born in Brazil almost quadrupled during the period. For many authors, mixed marriages are a good indicator of immigrant community integration in the host

    Full Text Available Objective – To identify patterns of patron behaviour in the library in order to improve space utilization. Design – Ethnographic data-gathering, including observations and a qualitative survey. Setting – Music library of a large public university. Subjects – Library patrons, primarily music students but also music faculty, other students and faculty, and regional music professionals and amateurs. Methods – In the exploratory phase, complete (i.e., incognito participant observers recorded patron characteristics and behaviours in four zones of the library (the technology lab, the stacks, the reference area, and study carrels. They conducted a series of five-minute-long visual sweeps of these zones at five-minute intervals. Observers were not given any checklist, but were told to record anything they saw regarding the personal characteristics, behaviours, and activities of patrons. The data collected resulted in what the investigators called “flip books” (a series of images recorded in close succession, which, when flipped, could give the illusion of movement. The data was analyzed using the grounded theory approach, a qualitative method to identify recurring themes on space use. A statistical analysis based on these themes was then conducted. In the second, explanatory phase, observers conducted new “sweeps,” or observations of the same library zones, this time using checklists to indicate the occurrence of specific activities identified in the first phase (solo vs. group activity, social interaction vs. study discussion, and use of technology. In addition, observers recorded patron entry and exit on “time cards,” and had all exiting patrons answer five brief questions about the types and volume of activities they had conducted in the various zones of the library. Main Results – The vast majority of the patrons were students. Most (at least three-quarters engaged in solitary activity, and a large majority used electronic

    Full Text Available Puesto que la Formación Inicial Docente (FID ha sido, en este último tiempo, parte de la agenda nacional del Ministerio de Educación de Chile, este estudio tiene como objetivo comprender los patrones de comunicación establecidos entre un grupo de profesores mentores y de profesores-estudiantes de pedagogía de una institución de educación superior de Concepción, Chile. La investigación es un estudio de casos múltiples de doce informantes, adscrita al paradigma interpretativo-hermeneútico. El instrumento de recolección de información es la entrevista semiestructurada, que fue analizada mediante el uso del software de análisis cualitativo Atlas-Ti que permitió segmentar, codificar y establecer relaciones entre los datos. El estudio constató que los patrones de comunicación en un proceso de mentoría se caracterizan por establecer tipos de interacciones reflexivas y promover la co-construcción de significados y la permanente autocrítica del quehacer pedagógico. Asimismo, el rol del mentor como apoyo y guía, resulta crucial en su relación con el profesor-estudiante.

    Full Text Available The patterns of infracommunity descriptors (diversity, dominance, abundance are compared when calculated with the number and body volume of the parasites in a sample of 26 southern pomfrets Brama australis collected in the area off Talcahuano, Chile. No numerical infracommunity descriptor was correlated with its corresponding volumetric descriptor. This single result casts doubts about the general validity of the infracommunity patterns described in the literature so far, because they are almost exclusively based on the number of parasite individuals per individual host, restricting communication with ecologists that use density or other measures of ecological abundanceLos patrones de los descriptores infracomunitarios (diversidad, dominancia, abundancia son comparados cuando son calculados en base a los números o al volumen corporal de los parásitos en una muestra de 26 reinetas Brama australis recolectadas en el área de Talcahuano, Chile. Ningún descriptor infracomunitario calculado con el número de parásitos estuvo correlacionado con los basados en el volumen corporal de los parásitos. Este resultado siembra dudas acerca de la validez general que pueden tener los patrones infracomunitarios registrados en la literatura ya que están casi exclusivamente calculados con el número de parásitos por individuo hospedador, lo que dificulta aún más la comunicación con los ecólogos, que usan la densidad u otras medidas de abundancia ecológica

    Full Text Available Equine viral arteritis (EVA is a contagious viral disease that frequently causes mild or subclinical infections in adult horses. Only one EAV serotype has been described. However, there are differences in antigenicity, pathogenicity and neutralization characteristics of virus field strains. The interaction of two viral proteins, GP5 and M, is critical for infectivity and amino acid changes in the GP5 sequences have an effect on the neutralizing phenotype, regardless the effects of other viral proteins. The objective of the present study was to evaluate the neutralization phenotypes of the 5 unique Argentine EAV strains reported and to compare them with the neutralization phenotypes of the EAV-UCD reference strain, with special emphasis on the analysis of M and GP5 proteins. The strains had a similar neutralization phenotype pattern when anti-EAV serum, derived from EAV seropositive horses, was used in the analysis. Meanwhile, low titers were observed when equine polyclonal anti-EAV reference sera were used in the assay. Argentine strains have almost the same amino acid substitutions, with the exception of LP01 strain, that mainly involves the first variable region V1, especially in neutralization sites B and C. However, they are fairly different from the EAV-UCD strain. Nevertheless, the nucleotide and amino acid differences observed among the Argentine strains LP02/R, LP02/C, LP02/P and LP-LT-ARG did not show any variations in the neutralization phenotype.La arteritis viral equina (AVE ocasiona infecciones, en su mayoría subclínicas, pero puede causar abortos y enfermedad respiratoria.

    Full Text Available Uneven distribution of biodiversity over the Earth's surface is a consequence of historic, environmental and functional factors. In this paper, spatial patterns of amphibians, reptiles, mammals and birds have been studied in a biogeographical gradient between Pyrenean and Mediterranean environments in Navarra. Also, the relationships between biodiversity, species richness, and biogeographical gradient have been measured with directional semivariograms and GIS. Results show correlations between biogeographical change and spatial patterns of vertebrates: reptiles have the higher values of species richness in the ecotone, while amphibians have an uneven distribution. Mammals and birds show lineal correlations with biogeographical change but in opposite directions.

    Full Text Available Na esfera Nacional, as Medidas Provisórias 563/2012, 582/2012, 601/2012 e 612/2013 propõem a substituição da alíquota previdenciária patronal do INSS por uma alíquota tributária de 1% ou 2% sobre o faturamento, esta alteração sendo feita em setores econômicos intensivos em trabalho. O presente estudo avalia impactos econômicos dessas mudanças sobre os agregados, setores e famílias na economia brasileira. Os resultados sugerem que os efeitos da substituição se devem exclusivamente à redução da carga tributária embutida na proposta, mas sem impacto relevante na redução das distorções do sistema tributário brasileiro.

    Full Text Available We estimate the population size and density, habitat preferences, habitat breadth and probable population trends in the last 25-15 years of the diurnal terrestrial bird species breeding in La Palma island (Canary islands. Data were obtained in a large extensive census program carried out during the 2007 nesting period using line transects that allowed detectability estimations. We also explored patterns of species richness both at inter-habitat and local scale. Local species richness (species per 0.5 km transects showed an important geographical component, increasing from south to north, from west to east, and reaching maximum values at altitudes around 600-1,000 m a.s.l. It was also positively related to vegetation development (specially in the herbaceous and shrub layer, and negatively associated with urbanization and agriculture. Total bird density reached the highest figures in the ‘monteverde’ (laurel and heath forests ca. 650 aves/km2, and in the transition pinewoods-laurel forests (509 aves/km2, while the lowest figures were recorded in high altitude shrublands (153 aves/km2 and recent lava fields (58 aves/km2. The bird species with lower population sizes are Falco [peregrinus] pelegrinoides, Burhinus oedicnemus distinctus, Upupa epops, Carduelis carduelis, Miliaria calandra and Petronia petronia, while the last five species have undergone more negative population trends in the last 15-25 years.

    Se estiman los niveles poblacionales, las densidades ecológicas, los principales patrones de preferencia de hábitat, las posibles tendencias demográficas habidas en los últimos 25 y 15 años, y el estatus de conservación actual de las especies de aves terrestres diurnas reproductoras en la isla de La Palma. Los datos fueron obtenidos durante el periodo reproductor de 2007, utilizando transectos lineales. En total se efectuaron 437 transectos de 0,5 km repartidos por toda la

    Full Text Available Uno de los principales objetivos de la biogeografía es determinar si las especies se distribuyen en el espacio en forma aleatoria o si existen grupos de especies con patrones de distribución comunes. En el presente estudio determinamos a través de técnicas cuantitativas si existen corotipos, es decir, grupos de especies con patrones de distribución común entre los árboles y arbustos en la zona de transición climática mediterráneo-templada de Chile, Octava Región de Chile. Adicionalmente, evaluamos la relación entre el clima y la distribución de los diferentes grupos de árboles y arbustos de la Octava Región. El análisis de agrupamiento de especies permitió definir 24 corotipos significativos, de los cuales 18 responden significativamente con alguna variable ambiental analizada. La temperatura media anual, la temperatura media invernal y la temperatura media de verano resultaron ser las variables que mejor explican el patrón de distribución de la mayoría de los corotipos. Las tendencias geográficas de los corotipos y su relación con las variables ambientales fueron evaluadas mediante un análisis de ordenación. Los resultados señalan que los corotipos con distribución en la cordillera de los Andes se correlacionan con la temperatura de invierno en tanto que los corotipos con distribución costera se correlacionan con la mediterraneidad. Se discute respecto de la utilización de una nueva aproximación para el análisis fitogeográfico y de su utilidad en el estudio de la relación entre la vegetación y los factores ambientales que determinan su distribuciónOne main aim of biogeography is to determine if species are randomly distributed or if there exist groups of species with common distributional patterns known as chorotypes. In this study, we determined through quantitative techniques if there exists such chorotypes for trees and shrubs in the transitional Mediterranean-temperate climatic zone of Chile, Eigth

    Full Text Available Abstract (english Analysis of cross-sectional and follow up clinical studies, of hypertensive patients with the different left ventricular geometric patterns, provide plausible explanations for the transition from hypertensive heart disease to the two distinct phenotypes of systolic and diastolic congestive heart failure. According to the LIFE study treated-uncomplicated patients, with normal ventricular geometry (12%, concentric remodeling (11 % and concentric hypertrophy (34 %, may evolve to the eccentric hypertrophy pattern. Patients with the eccentric hypertrophy pattern have selective sympathetic activation and progressive enlargement of the left ventricular cavity with thinning of its walls. This pattern goes on to a stage of systolic dysfunction with diminished ejection fraction and enhanced degradation of the collagen matrix. On the other hand, patients with the concentric hypertrophy pattern have predominant activation of the renin-angiotensin-aldosterone system and progressive shrinking of the left ventricular cavity with thickening of its walls. This pattern usually precedes the stage of diastolic heart failure with preserved ejection fraction, impairment of relaxation and increased deposition of collagen in the myocardial interstitium. Thus, ventricular remodeling preceding diastolic heart failure is opposite to that of hypertensive patients who go on to develop systolic heart failure.

    Full Text Available Los peces herbívoros son organismos que deben suplir los requerimientos de su economía energética a partir de una fuente de alimento con un bajo contenido de nutrientes y energía. Dos de las interrogantes más importantes en relación con la herbivoría por peces son: i ¿cuáles son los factores que influyen en la selección o rechazo de un determinado item dietario? y ii ¿son capaces los peces herbívoros de extraer los nutrientes y energía necesarios para suplir sus requerimientos energéticos en base a una dieta de macroalgas?. En este trabajo se estudiaron en dos especies de peces herbívoros, Scartichthys viridis y Girella laevifrons, los patrones de selectividad dietaria en terreno y laboratorio, la eficiencia de asimilación y la relación entre los patrones encontrados con la composición química del alga. Los resultados obtenidos señalan que la dieta de estos organismos se compone en más del 90% de macroalgas bentónicas. En terreno ambas especies presentan una conducta trófica no selectiva en verano y selectiva en invierno, prefiriendo el consumo de algas verdes. En los experimentos de selección dietaria ambas especies presentan un patrón similar caracterizado por la preferencia de algas verdes y rojas por sobre algas pardas. Los resultados de los experimentos de asimilación, indican que Girella laevifrons presenta tasas de asimilación mayores que Scartichthys viridis, siendo en la primera las algas verde Ulva y Enteromorpha las que presentan una mayor eficiencia de asimilación. Los resultados sugieren una fuerte relación entre el patrón de selección trófica observado en estas especies y la relación entre composición del alimento y características digestivasHerbivores are organisms that must meet their energy and nutrients requirements from a food source that typically has been characterized as having low nutritional value given their low concentration of nutrients and energy.

Se presenta una lista exhaustiva de las especies en la que se consigna el grado de adaptación a la aridez de cada una de ellas; un análisis de la calidad del inventario y la estimación de la riqueza total de especies; una evaluación de los patrones de distribución y riqueza, y la identificación de áreas de significativa mayor riqueza o hotspots. Los resultados indicaron que 25 especies con diferente grado de adaptación a la aridez habitan la península, aunque se estima que la riqueza total del área debería ser de 27. Además, se reconoció que los rangos de distribución de los tenebriónidos siguen una distribución log-normal y que sólo 3 especies son endémicas. Espacialmente, la riqueza se distribuyó de forma agregada en la península y se determinaron 10 hotspots. Finalmente, considerando que en la península Valdés están permitidas actividades productivas que originan una importante degradación del hábitat, se examina la implicancia de los resultados para la conservación de los tenebriónidos epigeos.We conducted a study of the biogeographic patterns of epigean tenebrionids (Coleoptera: Tenebrionidae that inhabit the Protected Natural Area Península Valdés (Chubut, Argentina, based on data obtained from collections and collecting trips.

    Full Text Available During the last decades, limnological studies on Chilean systems have contributed to know the species composition and main environmental variables of many water bodies distributed over a wide latitudinal interval, from 18º to 53º S. However, we still lack of a comprehensive view about the structure and functioning of regional freshwaters. In this work we review the available information about pelagic biota from Chilean basins, in order to reveal patterns of species distribution and their possible association with environmental variables. We built presence-absence matrices for phytoplankton, zooplankton and fish over lakes and basins. From this database, we performed parsimony analysis of endemicity as a tool for determining fundamental distribution patterns of freshwater biota. Also, we assessed the relationship between species occurrences and some available site-related variables. Our results indicated that latitude exerted the strongest influence on species distribution, although altitude, longitude, and area also exerted significant effects for some groups. On the other hand, our results suggest a relationship between the degree of vagility of the groups and the degree of metacommunity structuring, related to the number of endemicity areas.Durante las últimas décadas, los estudios limnológicos en sistemas chilenos han contribuido al conocimiento de la composición de especies y de las principales variables ambientales de muchos cuerpos de agua distribuidos sobre un amplio intervalo latitudinal, desde los 18º a los 53º S.

    We sought to determine the relative frequency and nature of personal display of cigarette packs by smokers in two Australian cities where 30% front-of-pack and 90% back-of-pack health warnings have been used since 2006 and comprehensive tobacco marketing restrictions apply. An observational study counted patrons, active smokers and tobacco packs at cafés, restaurants and bars with outdoor seating. Pack orientation and use of cigarette cases were also noted. Overall, 18954 patrons, 1576 active smokers and 2153 packs were observed, meaning that one out of every 12.0 patrons was actively smoking, and one of every 8.8 patrons displayed a pack. Packs were more frequently observed in lower socio-economic neighbourhoods, reflecting the higher prevalence of smoking in those regions. Packs were displayed less often in venues where children were present, suggesting a greater tendency not to smoke around children. Most packs (81.4%) were oriented face-up, permitting prominent brand display. Only 1.5% of observed packs were cigarette cases, and 4.2% of packs were concealed by another item, such as a phone or wallet. Tobacco packs are frequently seen on table-tops in café strips, providing many opportunities for other patrons and passers-by to be incidentally exposed to cigarette brand names and imagery. Use of cigarette cases is rare, suggesting that smokers eventually habituate to pictorial warnings on branded packs and/or find repeated decanting of each newly purchased branded pack into a case to be inconvenient.

    Full Text Available INTRODUCCIÓN: En Colombia no existen estudios específicos de prevalencia de consumo de heroína. Este artículo evalúa los patrones de consumo de esta sustancia en un grupo de consumidores de la ciudad de Medellín y su área metropolitana, evidenciándose que el consumo empieza a ser una amenaza para la salud pública por las particulares formas de consumo, entre las que se incluyen prácticas de riesgo. OBJETIVO: Evaluar el consumo de heroína en la ciudad de Medellín y su área metropolitana. MÉTODOS: La investigación tuvo un enfoque mixto mediante el estudio de casos múltiples hasta saturar cada una de las variables y categorías propuestas. Se accedió a 42 consumidores de heroína de centros de tratamiento de la ciudad de Medellín y área metropolitana mediante la técnica de "bola de nieve", proceso que se realizó entre los meses de julio y septiembre de 2008. La información se recolectó mediante una entrevista estructurada, cara a cara, que consultó el tipo de heroína consumida, vías de administración, frecuencias de consumo, utensilios utilizados, prácticas de consumo y rituales que acompañan estas prácticas. Los datos cuantitativos se analizaron con el paquete estadístico EPI-Info 2.000 y los cualitativos con Atlas ti, versión 5.5, para Windows. RESULTADOS: Los consumidores eran predominantemente hombres, solteros, con edades comprendidas entre los 18 y los 23 años, sin hijos y muchos con estudios universitarios no terminados. Mayoritariamente se ubicaban en un estrato socioeconómico medio, tenían antecedentes familiares de consumo de sustancias psicoactivas y se iniciaron en el consumo de heroína entre los 15 y los 17 años. Tienen formas particulares de nombrar la heroína, los consumidores, y poseen rituales propios para consumir esta sustancia. En el artículo se presentan detalles de la heroína que consumen, la parafernalia y las prácticas asociadas a dicho consumo. CONCLUSIONES: El consumo de heroína es

    Full Text Available I summarize what is known about the mediterranean ecosystem represented in San Carlos de Apoquindo (33º 23' S, 70º 31' W, a rugged area of 835 ha located ca. 20 km east of downtown Santiago on the Andean foothills. This site attracted numerous researchers during 1976-1990 because of its proximity to Santiago and its relatively protected status. I review the literature, and provide unpublished information on this site. A total of 132 literature entries describe the ecology of San Carlos de Apoquindo, in about 30 topics. The shrub and herbaceous vegetation have been well studied, but little is known about the respective seed banks. Among animals, small mammals, rabbits, and avian and mammalian predators are the best investigated, whereas epigean arthropods, amphibians, lizards, snakes, passerine birds, and scavengers of all types are the least studied. Thematically, interactions from plant/climate, to plant/soil, to plant/herbivore, to herbivore/predator interactions, and to decomposition of animal carcasses, have been addressed. But gross inequalities exist on the thoroughness with which each topic has been researched. The best studied aspects deal with plant/herbivore and herbivore/predator interactions. Up to now, no description existed of soils and climate in the area, which I present in this paper. Taking advantage of the long-term aspect of the research at the site, I highlight temporal variation patterns. And because of the different landscape aspects present at the site, I also highlight data that depict such spatial variability. In general, San Carlos de Apoquindo has contributed greatly to the understanding of ecological processes in central Chile. I call for renewed efforts at studying this site's ecology from an ecosystem perspectiveResumo lo que se conoce acerca del ecosistema mediterráneo representado en San Carlos de Apoquindo (33º 23' S, 70º 31' O, un área con alto relieve y de 835 ha localizada ca. 20 km al Este del centro

    Cancer patients and their caregivers want information about their disease and are interested in finding health information online. Despite the abundance of cancer information online, it is often fragmented, its quality is highly variable, and it can be difficult to navigate without expert-level knowledge of the cancer system. The Patient & Family Library at the Princess Margaret Cancer Centre offers a broad collection of high-quality cancer health information and staff are available to help patrons refine their questions and explore information needs that they may not have considered. The purpose of this research study was to deconstruct patrons' information-seeking behaviors in the library to assess the feasibility of replicating the services provided in the library through a Web app, extending the service beyond the walls of the cancer centre. The specific aims of this research were to understand (1) how patrons approach information seeking in the library (interface design), (2) how patrons communicate their informational needs (information categorization and metadata requirements), and (3) what resources are provided to address the patrons' information needs (collection development). We employed a qualitative, instrumental case study to deconstruct patrons' health information-seeking behavior. The study population included patients, the librarian, and library volunteers. Ethnographic observation was conducted at the library over 3 days and key informant interviews with library staff were conducted to address the first aim. A closed card-sorting activity was conducted to address the second aim and the library shift logs and Search Request Forms (SRFs) were reviewed to address the third aim. A total of 55 interactions were recorded during the ethnographic observation and nine semistructured interviews were conducted during the key informant interviews. Seven library patron personas were identified: (1) Newbie, (2) Seasoned, (3) Direct, (4) Window Shopper, (5

    Full Text Available El rol e impacto de los herbívoros en la trama trófica de comunidades intermareales rocosas podría ser más diverso y complejo de lo considerado hasta ahora, particularmente en el caso de consumidores de mayor tamaño y abundancia como el molusco placóforo Enoplochiton niger. Esta especie es uno de los pastoreadores de mayor tamaño (hasta 20 cm e importancia ecológica en las costas rocosas del norte de Chile, pero también una de las especies menos conocidas en términos tróficos. Este trabajo presenta una evaluación de los patrones dietarios de E. niger en cuatro comunidades del norte de Chile, distribuidas en 1.000 km de costa y muestreadas estacionalmente entre invierno 2004 y otoño 2006. Además se analizó la relación de su dieta con factores biológicos y físicos, incluyendo el efecto potencial del evento El Niño 2004-2005 ocurrido durante el período de estudio. A nivel regional, el espectro dietario de E. niger abarcó un total de 98 recursos (60 ítemes algales y 38 ítemes invertebrados, y los ítemes más importantes fueron organismos sésiles con formas de crecimiento incrustante o en capa. E. niger mostró una gran amplitud de nicho tanto a nivel regional como local (rango: 20,7-28,0; índice de Levins, con una riqueza dietaria a nivel individual independiente del tamaño corporal. Tanto el número de ítemes dietarios consumidos por individuo como la composición taxonómica de la dieta no mostraron diferencias significativas entre comunidades, pero variaron significativamente entre el período asociado al evento El Niño y el período posterior. No hubo ninguna relación clara entre los patrones dietarios de E. niger y los niveles contrastantes de intensidad de surgencia entre las comunidades estudiadas. Los resultados muestran que E. niger es un consumidor generalista y polífago, y un potencial omnívoro, el cual podría tener un alto impacto sobre los patrones de ocupación de espacio en la comunidad intermareal

Metodología: estudio cualitativo, descriptivo, basado en la técnica de análisis de contenido. Durante el segundo semestre de 2009 se valoraron los patrones funcionales de salud de pacientes inscritos en el Programa de Prevención y Control de Tuberculosis de tres instituciones prestadoras de salud de carácter público de Villavicencio, Meta. Resultados y discusión: los patrones más alterados son el patrón de actividad y ejercicio, patrón de nutrición y metabolismo, patrón cognoscitivo perceptual y patrón de autopercepción y autoconcepto. La fatiga y la disnea comprometen los desplazamientos a la institución de salud, la disminución de la energía dificulta mantener un empleo, lo que afecta los ingresos familiares. Hay desconocimiento acerca de aspectos relevantes para el control de la enfermedad. Se presentan manifestaciones de tristeza y aislamiento asociadas a la percepción social negativa de la enfermedad. Conclusiones: el servicio del equipo de salud debe responder a las situaciones complejas de los enfermos, que van más allá de la administración del tratamiento. Enfermería tiene un rol protagónico en la creación de escenarios de cuidado apropiados y en el fomento de la interdisciplinariedad para la atención integral de los enfermos. Se recomienda desarrollar intervenciones individualizadas con guías de cuidado de enfermería y de manera particular mejorar la información suministrada a las personas acerca de la enfermedad, el tratamiento y las estrategias de prevención y de control de la transmisión.Objetivo: Determinar as alterações dos padrões funcionais da saúde mais freqüentes em pessoas em tratamento contra a tuberculose pulmonar.

Nuestros datos sugieren que T. niger es un generalista polífago cuyos patrones de consumo son fuertemente modulados por la fluctuación t��rmica ambiental. Además, hipotetizamos que T. niger puede usar estrategias oportunistas y selectivas sobre distintos recursos, y que su conectividad y posición trófica serían más complejas que las de un simple consumidor primario.The role and impact of herbivores on rocky intertidal food webs could be more complex and diverse than previously considered, particularly in the case of larger and more abundant consumers such as the black urchin Tetrapygus niger (Molina in the coast of Chile. In this context, we analyzed the variation in diet richness and composition of the black urchin in four rocky intertidal communities over a 1,000 km stretch of coast in northern Chile, sampled seasonally between the austral winter of 2004 and spring of 2005. The 2004-2005 El Niño event took place during the study, and we incorporated its potential effects to this evaluation. For each community and season, we measured the abundance of species present in 45 quadrants (0.25 m² distributed between five permanent blocks, collecting about 10 individuals of T. niger to measure their body size (dry biomass and maximum diameter and to determine the number, identity and occurrence frequency of dietary items in their gastric tract. We collected a total of 251 urchin individuals, which consumed 89 items of algae (64 % and invertebrates (36 %; including other herbivores. A significant inverse relationship between the number of ingested animal items and body size suggests that T. niger changes its diet throughout the ontogeny. Dietary niche breadth was high but tended to decrease toward lower latitudes. The spectrum and occurrence frequency of dietary items were not significantly different among communities, despite their marked differences in upwelling

    Full Text Available En este artículo se identifican algunos de los patrones de organización presentes en el sistema social encargado del manejo de los residuos sólidos urbanos del Distrito Federal y del Estado de México. El supuesto de partida fue considerar a dichos residuos como un espacio de confluencia de relaciones sociales, susceptibles de ser mapeadas y estudiadas con el enfoque del análisis de redes sociales. Para ello se tomó en cuenta a los municipios, a las empresas y a la sociedad civil. La información que permitió observar esta organización provino de los responsables de medio ambiente y de servicios públicos municipales, de las estadísticas oficiales y de la bibliografía especializada en el tema. Existe un sistema complejo de gestión de residuos, consistente en procesos de retroalimentación, etapas diferentes de organización e información que lo dinamizan e innovan, pero que también lo atomizan, y esto provoca que la toma de decisiones sea limitada frente a la magnitud de la situación.

    Full Text Available En las ciudades, los espacios verdes públicos forman uno de los principales articuladores de la vida social, siendo lugares de encuentro e integración de los habitantes. La OMS considera que la superficie óptima mínima destinada a espacios verdes por habitante debe ser de 10 a 15 m2. No obstante, este indicador no garantiza la igualdad de acceso a todas las personas. Por ello, la superficie disponible y la ubicación de dichos espacios son factores fundamentales para asegurar esa igualdad y, por consiguiente, la calidad de vida urbana. Este trabajo centra su investigación en el análisis de los distintos modos de acceso y los patrones de uso de espacios verdes del Área Metropolitana de Mendoza, Argentina, con el fin de desarrollar un plan de inclusión de nuevos espacios verdes que aborden los ejes de cantidad y de igualdad de acceso peatonal. Con ese objetivo, se realizan encuestas a los usuarios, la cuales demuestran que la mayor parte de ellos llegan a estos sitios caminando, que existe relación entre el medio de transporte y la frecuencia con la que asisten a los espacios verdes, y que los radios de acción de dichos sitios varían entre 300 y 400m, dependiendo de la superficie del espacio.

La capacidad de determinar de forma precisa las características fundamentales del movimiento a través de la observación es fundamental para ofrecer una evaluación, diagnóstico y corrección eficaces. Del mismo modo, la capacidad de controlar con precisión la ejecución del movimiento es central para la producción de patrones de movimiento deseados. La observación de errores del movimiento (por entrenadores y terapeutas y la corrección de estos errores (por atletas o pacientes dependen fundamentalmente de diferentes sistemas de percepción que pueden diferir en su sensibilidad, unidad de control y capacidad de entrenamiento. En este trabajo se examina en primer lugar, la habilidad de percibir las características del movimiento y los patrones fundamentales (es decir, la cinemática del movimiento mediante una revisión bibliográfica de expertos del deporte que han investigado tanto las capacidades de los atletas como de los observadores expertos. Importantes diferencias en el conocimiento especializado referente a las habilidades en percepción visual son discutidas, centrándose en las contribuciones perceptivas y motoras a la habilidad de percepción. Las teorías relacionadas con la percepción de otros patrones de movimiento, tales como la codificación común, son revisados haciendo especial hincapié en las implicaciones para los practicantes en habilidades. A continuación se consideran las limitaciones en la bibliografía actual sobre la observación visual, en particular, la necesidad de examinar de forma más directa las capacidades perceptivas de los atletas para diferenciar de forma fiable los cambios cinemáticos. Además, de forma paralela, se analiza una cuestión clave como es la sensibilidad cinestésica del paciente o deportista, destacando la necesidad de conocer la

    1992-01-01

    Numerous health care facilities, located in downtown metropolitan areas, now find themselves surrounded by a decaying inner-city environment. Consumers may perceive these facilities as "old," and catering to an "urban poor" consumer. These same consumers may, therefore, prefer to patronize more modern facilities located in suburban areas. This paper presents a case study of such a health care facility and how strategic planning and marketing research were conducted in order to identify market opportunities and new strategic directions.

The species is present in 14 localities corresponding to 14 10x10 km UTM squares; 8 of them are published for the first time in this study. We corroborate the presence of the species in all the Protected Areas in Cuenca. Using the known occurrence data and a set of digital environmental variables such as current vegetation, climate, geology and elevation, we found that the distribution of the species seems to be mainly determined by the presence of Scots pine (P. sylvestris and Austrian pine (Pinus nigra subsp. salzmanii forests. Finally, a potential distribution map for the moth in Cuenca suggests that the species could inhabit other areas where it is presently unknown.Se ha realizado un estudio sobre la mariposa nocturna Graellsia isabelae (Graells, 1849 en la provincia de Cuenca, la cual se encuentra protegida en la región de Castilla-La Mancha.

    Full Text Available The Lemnaceae family lacks morphologic and anatomical characteristics with comparative aims and for that reason the molecular studies has been necessary a differentiation. In Costa Rica there are two species of Lemna: Lemna aequinoctialis and Lemna valdiviana. With the objective of a molecular characterization and differentiation of both species were extracted isoenzymes esterases. The study was carried out in the Molecular Genetics Laboratory of the School of Biological Sciences at Universidad Nacional, Heredia, Costa Rica. The technical electrophoresis in gel of polyacrylamida SDS-PAGE was used. It was difference in the pattern of isoenzymes between both species. According to previous molecular studies based on morphology and anatomy, flavonoides, isoenzymes, and DNA sequences of certain genes both species are very different; in addition they belong to different monophyletics groups. On the other hand, the importance of this molecular characterization is its possible use in water treatment, because the esterases have had important in the bioremediation. Also, species of the Lemnaceae family are used in the water treatment like bioremediation.

    Limited studies based in England and Australia reported misuse of anabolic-androgenic steroids (AAS) among homosexual men to enhance body image. Anecdotally, AAS are also being misused by homosexual men in the United States. Since many AAS and certain performance enhancing drugs (PEDs) are administered via injection, this poses a potential vector for the spread of infectious disease in an already at-risk population. This study compared and contrasted homosexual and heterosexual male gym clients regarding use of AAS and PEDs, use of alcohol and illicit drugs, seroprevalence of infectious disease, engagement in risky injection practices and sexual behaviors, and presence of psychiatric conditions. Recruitment and data collection occurred outside four exercise gyms in the San Francisco Castro District area between October 25, 2014 and March 10, 2015. Two hundred and twenty homosexual men and 73 heterosexual men completed the 114-item cross-sectional survey. Ten percent of homosexual men reported lifetime AAS use. Homosexual men had almost four times more sexual partners and were over 14 times more likely to knowingly have unprotected intercourse with a known HIV positive person than heterosexual men. In addition, a quarter of homosexual men who injected drugs admitted to sharing used syringes or needles with another person. Conclusions/Importance: The current study is the first to confirm AAS use among homosexual men in the United States. Homosexual men partook in high-risk sexual behaviors and injection practices which may place them at greater risks for contracting and spreading HIV and other infectious diseases.

    Cocaine- and amphetamine-regulated transcript (CART) is a hypothalamic anorectic neuropeptide that controls feeding behaviour and body weight. The study objective was to investigate the association of the CART prepropeptide gene (CARTPT) rs2239670 variant with obesity and its related anthropometric indicators among patients of a Malaysian health clinic in Kampar, Perak, Malaysia. A total of 300 Malay/Peninsular Bumiputera, Chinese, and Indian subjects (115 males, 185 females; 163 non-obese, 137 obese) were recruited by convenience sampling, and anthropometric measurements, blood pressures, and pulse rate were taken. Genotyping was performed using AvaII polymerase chain reaction-restriction fragment length polymorphism. Genotyping revealed 203 (67.7%), 90 (30.0%), and 7 (2.3%) subjects with the GG, GA, and AA genotypes, respectively, with a minor allele (A) frequency of 0.17. No significant difference in the CARTPT rs2239670 genotype and allele distribution was found between obese and non-obese subjects, and logistic regression showed no association between the mutated genotypes (GA, AA) and allele (A) with obesity, even after adjusting for age, gender, and ethnicity. Furthermore, the measurements did not differ significantly between the genotypes and alleles. No significant difference in the genotype and allele distribution was found among genders, but they were significantly different among ethnicities (P = 0.030 and P = 0.019, respectively). CARTPT rs2239670 is not a predictor for obesity among the Malaysian subjects in this study.

    .AbstractFilm festivals have increasingly been pointed out by scholars as key nodes of contemporary cinematic culture. In spite of their reputation as places for cultural celebration, the world of film festivals strikes as a particularly unequal and competitive one. Dominated by a few Euroamerican mega-events, film festivals seem full of hidden rules and dynamics regulating the movement of films and maintaining a hierarchical division. Focusing on two Latin American case studies: Central Station (Central do Brasil, Walter Salles, 1998 and Foreign Land (Terra estrangeira, Walter Salles and Daniela Thomas, 1995, this paper enquires about the consequences of this hierarchical structure of the film festival world for the international circulation of the Latin American cinema in the 90´s. While almost all non-Hollywood films with international ambitions are launched and promoted in several film festivals before they reach foreign commercial screens, the dynamics of this festival ‘tour’ where films are evaluated and passed through several filters (or dismissed on the way are closely related to the hierarchies of the film festival world. In this way, the festival tour has become a standardized tool of the international film marketing strategy that uses the logics and dynamics of the circuit to raise the artistic and cultural status of the film products targeted to international markets.Keywords: film festivals, film industry, international distribution, film marketing, film festival circuit, cultural discount, paratexts, Latin American cinema, world cinema.

    Full Text Available Reportamos el primer registro de la gaviota sombría (Larus fuscus en el estado de Veracruz; se trata de una especie cuya distribución geográfica ha estado expandiéndose, de Europa occidental hacia Norteamérica, desde la primera mitad del siglo XX hasta la fecha. Anida de forma regular en por lo menos dos áreas en el suroeste de Groenlandia, en las que la población reproductiva se ha estimado en más de 700 parejas. Su expansión parece estar ocurriendo también hacia el sur, ya que comenzó a reproducirse en las Islas Canarias a partir de 1995. El primer evento reproductivo confirmado en Norteamérica fue en Maine, EUA, en 2007. En México, el primer registro sucedió en 1979; la especie ha sido reportada en seis estados, con un notable incremento durante los últimos años. Nuestro registro ocurrió el 16 de marzo de 2008. La mayoría de los individuos registrados en el este de Norteamérica posiblemente provengan de poblaciones reproductivas ubicadas en Groenlandia o en Islandia, y quizá estén funcionando como puentes geográficos entre Europa noroccidental y Norteamérica. Con base en sus patrones migratorios y de expansión geográfica, y en el aumento de sus colonias reproductivas, L. f. graellsii es la subespecie que puede ocurrir más comúnmente en Norteamérica. Las características morfológicas del individuo registrado en este trabajo son consistentes con dicho taxón. Si consideramos la regularidad y la cantidad de registros en diferentes regiones del continente, es probable que la presencia de la especie se encuentre subestimada en las costas mexicanas del Golfo de México, siendo en realidad una especie regular, aunque poco abundante.

    Full Text Available Eurymetopum is an Andean clerid genus with 22 species. We modeled the ecological niches of 19 species with Maxent and used them as potential distributional maps to identify patterns of richness and endemicity. All modeled species maps were overlapped in a single map in order to determine richness. We performed an optimality analysis with NDM/VNDM in a grid of 1º latitude-longitude in order to identify endemism. We found a highly rich area, located between 32º and 41º south latitude, where the richest pixels have 16 species. One area of endemism was identified, located in the Maule and Valdivian Forest biogeographic provinces, which extends also to the Santiago province of the Central Chilean subregion, and contains four endemic species (E. parallelum, E. prasinum, E. proteus, and E. viride, as well as 16 non-endemic species. The sympatry of these phylogenetically unrelated species might indicate ancient vicariance processes, followed by episodes of dispersal. Based on our results, we suggest a close relationship between these provinces, with the Maule representing a complex area.Eurymetopum es un género de cléridos andinos con 22 especies.

Se obtuvo información de registros de mamíferos de Jalisco de diferentes colecciones biológicas nacionales y extranjeras. Se utilizaron las localidades de recolecta para realizar una cobertura de puntos. El estado se dividió en 159 unidades de clasificación geográfica (UCG´s de 15' por 15'. Se sobrepuso la cobertura de puntos, las UCG y algunos mapas de CONABIO para formar una matriz de presencia-ausencia. Se analizó la distribución de la riqueza por tipo de vegetación y altitud. Se observó un gradiente de riqueza que va desde las zonas tropicales hasta las semiáridas. Por altitud, la mayor riqueza se encontró entre los 1500 y 2000 m y la menor de los 4000 a 4500 m. Se aplicó una ordenación de Bray-Curtis y una clasificación con TWINSPAN. Ambas fueron consistentes en formar 2 grupos de mamíferos; uno con especies de la costa y el otro del noreste del estado, lo que refleja un gradiente climático. El porcentaje de variación acumulada fue del 94% y las variables del medio con mayor influencia fueron precipitación, temperatura, evaporación, altitud y vegetación.We analyzed the patterns of distribution of mammal species richness in Jalisco State and their relationships with some environmental factors. We retrieved distribution data from several national and foreign biological collections. We used the collecting localities to generate a spatial record of distribution points. The state was divided into 159 geographic units of classification (GUC's of 15' by 15'. We overlap the point cover, GUCs and some maps from CONABIO to create a presence-absence matrix. We analyzed the richness distribution by vegetation type and elevation. A richness gradient was observed from tropical to semiarid vegetation types and according to elevation; we observed higher richness between 1500 and 2000 m a. s

    Full Text Available The analysis of feces is a fundamental tool for field work, especially to identify the presence of certain species in an area. Fecal bile acids and their relative concentration follow patterns that are species-specific, and can be characterized by Thin Layer Chromatography (TLC. This technique has been used for differentiating feces of several mammal species; however it has never been used for Xenarthra species. In this work, 96 feces of Xenarthra species were analyzed by TLC to determine the bile acid pattern. The species were: Zaedyus pichiy (n = 10, Chaetophractus vellerosus (n = 5, Chaetophractus villosus (n = 57, Dasypus kybridus (n = 4, Priodontes maximus (n = 2, Tamanduá tetradactyla (n = 14 and Myrmecophaga tridactyla (n = 4. There were differences between the bile acid patterns of all the species, but not between males and females, nor between wild and captive animals of the same species. We found seven known bile acids, cholesterol and seven unidentified compounds (X1-X7. All the species had taurocholic, glycochenodeoxycholic and lithocholic acids, and cholesterol. Only C. villosus had deoxycholic acid (Rf: 0.30 ± 0.01. Z. pichiy, C. vellerosus and C. villosus had two or three bands of dehydrocholic acid (Rf between 0.29 ± 0.06 and 0.45 ± 0.02, while the other species had one or two. Z. pichiy had two unidentified bile acids, X6 (Rf: 0.85 ± 0.06 and X7 (Rf 0.93 ± 0.03, that were almost indistinguishable in other species. D. hybridus differed from Z. pichiy, C. vellerosus and C villosus because it did not have chenodeoxycholic acid and X7. T. tetradactyla was the only species without cholic acid and it differed from M. tridactyla because it had dehydrocholic acid. D. hybridus was the species with the lowest number of compounds (seven, and differed from the others because it did not have the X1 and X5 unidentified compounds. These results are the first for Xenarthra and would be very important for fu ture studies about the

    Full Text Available Using the Arduino development board (http://arduino.cc has become a very popular way to create hardware prototypes that bridge the divide between the physical world and the Internet. This article outlines how to use an Arduino, some off-the-shelf electronic parts, the Processing programming language, and Google Documents to create a push-button reference desk transaction tally device. The design: plugged into a computer at the reference desk, staff members push the appropriate button on the device when a reference transaction occurs, and the action is instantly tallied in a Google Document. Having a physical device on the desktop increases chances of proper collection of information since it is constantly visible and easily accessible, versus requiring staff members to click through a series of options in a piece of software running on the PC. The data can be tabulated in Google Documents or any other source that processes form-based HTML data. This article covers all of the major components of creating the project: - Constructing the Arduino circuit and programming it - Creating the Google Docs form - Creating the Processing program that will listen for information from the Arduino and send it to the Google Docs form

    Full Text Available The distribution of Concholepas concholepas (Mollusca, Gastropoda, Muricidae is limited to the coasts of Chile and southern Peru. Almost all studies of this gastropod have been carried out in open coastal systems, rather than the fjords and channels of southern Chile, despite the fact that this area represents ca. 95 % of the total coastline in this country. Although there is a large volume of background literature on C. concholepas, almost nothing is published about early larval development under natural conditions, mostly because early veligers have rarely been found in nature. This study is the first attempt to determine the spatial and temporal abundance and size patterns of C. concholepas larvae in their natural environment throughout all of their developmental stages until they settle. Weekly plankton samples were obtained at the surface and at 8 m depth in four locations in southern Chile in combination with temperature and salinity records in each location. Settlement was quantified using artificial substrates in all locations. We have observed that C. concholepas larval development occurs throughout the entire year in Chilean inland seas, with early veliger larvae being released mostly from August to March, reaching the competent stage around June to August, and settling between July and August. Thus, larvae appear to have a long planktonic development that can last between 6 and 12 months. Differences in local hydrology could affect larval development of C. concholepas in this region. Further oceanographic and ecological investigation is necessary in order to answer the questions and hypotheses originated from this studyConcholepas concholepas (Mollusca, Gastropoda, Muricidae se distribuye entre las costas del sur de Perú y extremo sur de Chile.

    Full Text Available Objective - To assess e-book delivery on handheld devices provided to public library patrons, particularly housebound or visually impaired patrons and the users of a mobile library. Design - Product trial with a post-trial questionnaire for patrons and a post-trial focus group discussion among participating library staff. Setting - Mid-to-large size public library system in the United Kingdom. Subjects - 23 patrons participated; the number of library staff participating is not identified. Although the target population initially identified was housebound people, patrons reliant on the mobile library, and visually impaired people, the project team determined that it did not have sufficient funds to upgrade the PDAs to be compatible woth their preferred software for the visually impaired, and therefore this group was eliminated from the study. Lack of funds was also cited as a factor in the team being unable to provide assistive technology for those users suffering from arthritis, though this group was not excluded from the study. Just over half the patrons were aged 60+, and more than half were female. Two patrons self-identified as housebound. Methods - e-books were downloaded onto Hewlett Packard iPAQ 1910 Pdas by library staff and were loaned to participants between Janualry and April 2004. Although the authors of the study state that "creating staff champions was an important objective in this project" (p.176, it is unclear whether staff were screened for positive attitude towards e-Books. Prior to the trial, staff members were provided with training and orientation, and participants were asked for their font sna d reading preferences. Suport for participating patrons was available from staff or via an accompanying user manual, e-mail, or telephone help line.

    Resumen: La embriogénesis somática representa una herramienta esencial en el mejoramiento genético y en la micropropagación clonal masiva de bananos mejorados. En el presente trabajo se analizaron los patrones morfológicos y anatómicos que ocurren durante la embriogénesis somática del banano Williams, dirigidos a conocer y mejorar este proceso. En la investigación se establecieron suspensiones celulares embriogénicas (SCE a partir de callo embriogénico obtenido de manos florales inmaduras masculinas, las cuales originaron abundantes embriones que regeneraron plantas. Hacia los tres meses de cultivo se detectaron embriones somáticos (ES primarios color blanco-crema en las manos florales de los nudos nueve a doce, contados a partir del ápice floral. Al cuarto mes estos ES primarios dieron origen al callo embriogénico, de color blanco crema, estructura granular, con abundantes ES torpedo en su periferia y con una organización celular en tres diferentes zonas. De este callo se cultivaron porciones pequeñas con ES torpedo en medio de multiplicación durante dos meses, dando origen a la SCE I. La misma se tamizó (250 µm para establecer la SCE II. El sedimento de células y los agregados celulares embriogénicos de ambas SCE se trasladó a medio de maduración. Transcurridos dos meses los embriones maduros se transfirieron a medio de conversión de embriones, lográndose regenerar plantas completas a partir de las dos semanas. Las SCE produjeron numerosos embriones somáticos maduros y mostraron una buena conversión de embriones a plantas y regeneración de plantas.

Este grupo ha sostenido las grandes capturas invernales reportadas desde 2000 y, dado su largo tamaño y concentración, ha justificado el interés de la industria pesquera como un potencial recurso para la pesca en el talud. Características reproductivas y patrones de distribución temporales/ espaciales de los desovantes de invierno corroboran la hipótesis que les relaciona a concentraciones migratorias de stock del norte de la plataforma Patagónica. Si se confirma esta hipótesis, estos datos resaltan la importancia de considerar estrategias de manejo dirigidas a stocks compartidos en el Atlántico SW.

    -PCE propuesto por García-Barros et al. (2002 no garantiza la detección de todas las áreas delimitadas por endemismos de distribución exactamente coincidente. Sin embargo, ese procedimiento es eficaz si se aplica asociado a un método de búsqueda de cladogramas que proscriba la homoplasia, como el principio de compatibilidad.

    Full Text Available Cheilodactylus variegatus is an abundant carnivorous demersal reef fish that lives in the shallow subtidal of the north-central Chilean coast. Characteristically, these environments are dominated by kelp forests of Lessonia trabeculata. This species preys on a great variety of benthic invertebrates, and shows particularly high consumption rates on amphipod crustaceans. In our study, two widely separated populations of C. variegatus were considered (central and northern Chile. Individuals that form part of these populations show considerable differences in their distribution, abundance and trophic behavior. In the northern zone, the species is abundant and both juveniles and adults are distributed along the whole bathymetric gradient. This contrasts with populations found in central Chile, which are more sparse and lack juveniles. The distribution and abundance patterns appear to be influenced mainly by the great abundance of diverse understory macroalgae in the northern subtidal, which harbors a large number of invertebrates, especially amphipods. In contrast, the understory algal abundance of the central zone is much lower, and does not show a direct relationship with the lesser abundance of amphipods. In general, C. variegatus maintains a high consumption rate on amphipods throughout its ontogeny but it includes several other prey items in later ontogenetic stages. The different understory algal assemblages, and their associated fauna, are likely to be the main factors influencing the patterns of abundance and distribution observed between these two geographically distinct fish populationsCheilodactylus variegatus es un pez demersal abundante que habita el submareal somero de la costa norte y central de Chile.

    Full Text Available OBJECTIVE: To examine the relationship between growth patterns in early childhood and the onset of menarche before age 12. METHODS: The study included 2,083 women from a birth cohort study conducted in the city of Pelotas, Southern Brazil, starting in 1982. Anthropometric, behavioral, and pregnancy-related variables were collected through home interviews. Statistical analyses were performed using Pearson's chi-square and chi-square test for linear trends. A multivariable analysis was carried out using Poisson regression based on a hierarchical model. RESULTS: Mean age of menarche was 12.4 years old and the prevalence of menarche before age 12 was 24.3%. Higher weight-for-age, height-for-age, and weight-for-height z-scores at 19.4 and 43.1 months of age were associated with linear tendencies of increased prevalence and relative risks of the onset of menarche before age 12. Girls who experienced rapid growth in weight-for-age z-score from birth to 19.4 months of age and in weight-for-age or height-for-age z-scores from 19.4 to 43.1 months of age also showed higher risk of menarche before age 12. Higher risk was seen when rapid growth in weight-for-age z-score was seen during these age intervals and the highest risk was found among those in the first tertile of Williams' curve at birth. Rapid growth in weight-for-height z-score was not associated with menarche before age 12. CONCLUSIONS: Menarche is affected by nutritional status and growth patterns during early childhood. Preventing overweight and obesity during early childhood and keeping a "normal" growth pattern seem crucial for the prevention of health conditions during adulthood.OBJETIVO: Evaluar la relación entre patrones de crecimiento en la infancia precoz y ocurrencia de menarca antes de 12 años de edad.

    The purpose of this paper is to explore the characteristics of bars where drug use was observed compared to those where no drug use was observed. The study was done through a combination of qualitative and quantitative techniques gleaned through observations and interviews. Among the most important of indicators were the type of activity (particularly dancing) and the level of rowdiness evident in the bars. In addition drug use bars had higher levels of other types of rule-breaking. Patron characteristics (more men) and behavioral patterns (more sexual risk-taking) also distinguished these bars.

Las relaciones biogeográficas regionales se determinaron utilizando información de las leguminosas de 12 áreas de América Central, América del Norte, América del Sur y las Antillas. Se emplearon 3 métodos de análisis: coeficiente de Jaccard, análisis de parsimonia (PAE y un análisis de patrones generales de distribución, como una visualización general de los trazos individuales de Croizat. También se revisaron filogenias de algunos géneros de leguminosas para determinar patrones de evolución geográfica. La mayor riqueza de especies encontrada al sur de la península se asocia con el gradiente climático en sentido norte-sur. Los resultados indican que esta área se puede dividir en 2 áreas biogeográficas (distritos: una franja septentrional y una franja meridional y al menos 5 subdistritos. Los análisis de parsimonia (PAE y los patrones generales de distribución son congruentes con los análisis de similitud.

    Full Text Available Los erizos regulares son uno de los principales grupos de organismos bioerosionadores que destruyen los arrecifes coralinos alrededor del mundo. En el presente estudio se determinaron los patrones de distribución y abundancia y las tasas de carbonato de calcio removido en el arrecife de Playa Blanca por Centrostephanus coronatus, una de las especies de erizos más abundante en este arrecife. Para este fin se realizaron cuatro visitas al arrecife entre 1997 y 1998 durante las cuales se contabilizó el número de individuos en cada una de las principales zonas arrecifales (Trasarrecife, Plataforma-Cresta, Frente, y Talud. Las tasas de erosión fueron determinadas por medio del análisis del contenido estomacal de un número representativo de individuos colectados en cada zona. Cada sistema digestivo fue calcinado para eliminar la materia orgánica y conservar solamente la porción inorgánica de carbonato de calcio. C. coronatus presentó sus mayores densidades hacia las zonas centrales del arrecife (12.4 ind/m² ; rango 0-48 ind/m² . La tasa de bioerosión promedio más alta de C. coronatus fue de 0.103 kgCaCo3 /m² /año en la Plataforma-Cresta (rango 0 a 0.69 kgCaCo3 /m² /año. En las otras zonas (trasarrecife y frente las tasas promedio de erosión fueron 0.071 (0-0.39 y 0.052 (0-0.31 kgCaCo3 /m² /año respectivamente. De acuerdo con estos datos fue posible comprobar que la destrucción de esqueletos de corales en este arrecife por esta especie de erizo es baja, comparada con la acción abrasionadora de este tipo de organismos en otras partes del mundo. Sin embargo, la acción combinada de C. coronatus con otros organismos bioerosionadores y con algunos factores ambientales adversos para los corales, puede estar provocando un desbalance entre los procesos normales de contrucción-destrucción arrecifal en la Isla GorgonaRegular sea-urchins are one of the main bioeroding organisms affecting coral reefs around the world.

    Full Text Available Literature in emotional management has considered that emotions of employees may have important organizational implications. In librarianship, emotions also play an important role in affecting librarians’ attitude to patrons and in turn his/her job performance. Yet the exploration of emotion has not been much studied in Taiwan’s librarianship. Hence, the purpose of this study is trying to explore librarians’ perception and causes of negative emotions in the library settings in Taiwan. The result indicates that librarians in Taiwan experience significant levels of negative emotions, and interpersonal relationship appears as one of the most important causes.[Article content in Chinese

    Alcohol-related harm is a substantial burden on the community in Australia and internationally, particularly harm related to risky drinking practices of young people in the night-time economy. This protocol paper describes a study that will report on the changes in a wide range of health and justice outcome measures associated with major policy changes in the state of Queensland, Australia. A key element includes trading hours restrictions for licensed premises to 2 am for the state and 3 am in Safe Night Precincts (SNPs). Other measures introduced include drinks restrictions after midnight, increased patron banning measures for repeat offenders, mandatory ID scanning of patrons in late-night venues, and education campaigns. The primary aim of the study is to evaluate change in the levels of harm due to these policy changes using administrative data (e.g., police, hospital, ambulance, and court data). Other study elements will investigate the impact of the Policy by measuring foot traffic volume in SNPs, using ID scanner data to quantify the volume of people entering venues and measure the effectiveness of banning notices, using patron interviews to quantify the levels of pre-drinking, intoxication and illicit drug use within night-time economy districts, and to explore the impacts of the Policy on business and live music, and costs to the community. The information gathered through this project aims to evaluate the effectiveness of the Policy and to draw on these findings to inform future prevention and enforcement approaches by policy makers, police, and venue staff.

In this official document, produced and promoted by the Chilean Government, the authors strive to present themselves as powerless to judge society or to explain historical events. However, they propose evaluations (evoked and inscribed of relevant sectors of society, offer an interpretation of history, and specifically, give explanation for the "military intervention" and the possible causes for the severe human rights violations during the dictatorship. Informed by the complementary theoretical approaches of SFL and CDA, I focus on Appraisal analysis (White 2000, 2003; Martin 1997, 2003, 2004; Martin & Rose 2003; Martin & White 2005 and a transitivity analysis of mental and verbal projections in the discourse, as tools for a more flexible and detailed exploration of the use of evaluation resources. This analysis allows us to create a systemic network of the patterns of grammatical and lexical resources used by the Commission to generate mitigation and self/others representation in the discourse. This linguistic analysis, inserted in a social practice, also offers a complementary understanding of the subjectivities found in the field of oral history, specifically in the study of testimonies that account for different and contradictory memories of the recent Chilean past (Stern 2006.Este artículo analiza algunos patrones de la realización de voz de la Comisión Nacional de Verdad y Reconciliación chilena de 1991, establecida después de la dictadura militar (1973-1990.

    Patrons of art galleries and museums, tourists visiting historic buildings, and sightseers viewing archaeological sites are generally unaware of the extent to which science and technology has contributed to the value of what they see. Many countries rely on cultural tourism to generate national wealth. The use of radiation of many kinds to assist in the conservation/restoration of cultural heritage artefacts is described in this paper. In particular, the paper will describe studies of the pigments used in historic Australian Indigenous art, the degradation of manuscripts written using iron-gall inks, the protection of statues against corrosion and the selection of lubricants for use in old machinery.

    offered the most balanced comparison because the numbers of enhanced and non-enhanced records were almost equal. The overall circulation of items with enhanced records published between 2000 and 2004 was 2.9% higher than for items with non-enhanced records, constituting a relative percentage difference of 30.7%. The relative percentage difference in this period was higher for books in science and technology (36.9%, followed by history (34%, language and literature (30.6%, and social sciences (25.7%. Enhanced records also had a positive impact on circulation for items published between 1990 and 2000 over their non-enhanced counterparts; however, this positive growth levelled off for items published between 2005 and 2008, with almost equal circulation rates between items with enhanced and non-enhanced records during this period. The impact of the three MARC fields was examined, and the presence of the MARC 505 field was most associated with increased circulation rates, in part because it was the most commonly used field of the three for the period in question. The number of records with MARC 520 and 856 fields was not sufficient to draw firm conclusions about their impact on circulation. While not the focus of the study, the circulation data also suggested a preference for current titles among all four subject areas, most significantly among the social sciences and science and technology. The second part of the study found that keyword searching was the most common strategy employed by patrons, with 49.6% of the 130 searches examined falling into this category. Keyword searches most commonly led to the borrowing of items from the history LC classes, while title searches were most common in science and technology. Known item searches (title or author accounted for 45.9% of the overall searches analyzed. However, in most cases, the search terms used that led to a title circulating were found in the title and subject fields, rather than in a content-enriched MARC field. The

    2013-07-01

    Full Text Available This article reports on a 2012 survey of library patrons at ATLA-affiliated libraries regarding academic reading habits and preferences. The research questions for the study were: [1] To what extent is academic reading done as e-reading?; [2] What features do participants value in e-books?; [3] What library sources do patrons want made available to them electronically?  The method used in the study was an online survey. A total of 2,578 individuals took the survey in the spring of 2012. Key findings were that half of respondents regularly read journal articles on a computer screen and  one  in five regularly reads or listens to e-books in their academic work. Participants wanted e-books to enable them to perform keyword searches, move around quickly within the text, and annotate the text electronically. Seven out of ten participants stated that they would like libraries to provide reference works, Bible commentaries, circulating titles, and textbooks in electronic format. It appeared that the distinction between library-owned resources and those owned by an individual disappeared in the minds of many respondents. The author concludes that theological library directors should consider spending a significant proportion of their collection budget on electronic resources now, despite ongoing difficulties that academic publishers face in making a transition to digital publishing. The author also interprets findings in light of Fred Davis’ model of technology acceptance.

    The use of complementary and alternative medicine including herbal medicine is increasing in many countries including Ghana. However, there is paucity of research on the perspectives of patrons of herbal medicine regarding the facilitators and barriers of herbal medicine use. This study sought to investigate the facilitators and barriers of herbal medicine among Ghanaian adults who use one form of herbal medicine or the other. The study employed an inductive exploratory qualitative approach. It was conducted at a private herbal clinic in Accra. Purposive sampling was employed to recruit 16 participants. Data collection was through individual face-to-face interviews and these were transcribed and analysed using content analysis procedures. It was realized that the factors that enhanced the use of herbal medicine included use of convincing information to enhance the initiation of herbal medicine use, effectiveness of herbal medicine, personal preference for herbal medicine, perceived ineffectiveness of western medicine and integration of spirituality in herbal medicine. The factors that hindered herbal medicine use included negative perceptions and attitudes about herbal medicine, poor vending environment, poor knowledge of vendors, high cost of herbal products at credible herbal clinics and inconsistent effectiveness of some herbal products. Participants desired that the national health insurance scheme will cover the cost of herbal medicine to alleviate the financial burden associated with herbal medicine use. Although some Ghanaians patronize herbal medicine, the negative perceptions about herbal medicine resulting from deceitful producers and vendors call for enhanced education and monitoring to ensure that effective herbal products are used.

    Full Text Available Mixed bird flocks are groups of individuals from different species that travel and forage together. Such groups are common in several bird communities around the world. We present species composition and activity patterns of mixed bird flocks in a region of the Central Andes of Colombia. We compared the number of species per flock, as well as the number of flocks among 3 different habitats. We tested hypotheses concerning the flocks daily activity and the co-occurrences of species within them. We recorded 75 species, and the species number per flock varied from 4 to 21. Our data suggest that habitat affects the number of flocks but not their species number, and that the activity of flocks is similar throughout the day. In addition, the association of birds in flocks is affected by interspecific facilitation, with some species co-occurrences found more times than expected by chance. We hypothesize that some tanager species could have a role in flock cohesion. We witnessed 2 predator attacks upon flocks, a number of agonistic interactions among flock members, and squirrels following bird flocks. Our results meet some general patterns described for mixed bird flocks.Las bandadas mixtas de aves son grupos de individuos de diferentes especies que viajan y forrajean juntos, y son comunes en varias comunidades de aves alrededor del mundo.

Les rythmes de travail sont la principale cause de fatigue, car les périodes de repos n’autorisent pas une récupération suffisante. Ainsi, nous notons une accumulation de la fatigue d’ordre psychologique tout au long de la saison de pêche. Cette récupération est limitée par les troubles du sommeil observés à bord.

The data were collected in natural situation. Our methodology combined direct observation with non-directive interviews.The work rhythms aboard trawlers (phases of work and rest alternation are the main cause of the captain’s fatigue. The short periods of rest do not authorize a sufficient recovery. Thus, we note a fatigue accumulation throughout the trawling season. In addition, the recovery is restricted by the sleep disorders observed during the embarkations. The analysis of the trawler captain’s activity reveals workload, causing stress, as well as risk-taking in a diminished vigilance context.Analizamos los procesos de fatiga a traves de la actividad de tres capitanes de pesca de los barcos pescadores pelágicos.

Se analizaron los patrones de riqueza y biogeográficos de las serpientes de Santa Fe, Argentina, para priorizar áreas para su conservación y evaluar si las reservas existentes coinciden con ellas. Los patrones de diversidad y distribución fueron establecidos mediante el análisis de 2.532 especímenes de ofidios de Santa Fe, obtenidos en muestreos de campo y revisión de colecciones, complementados con registros bibliográficos y un banco de datos regional de 8.000 ejemplares. Se determinaron las áreas de endemismos de serpientes, las que fueron comparadas con las divisiones fitogeográficas. Se dividió Santa Fe en 16 celdas de un grado de latitud y longitud, para comparar su riqueza, similitud y complementariedad, aplicándose un método para priorizar áreas de conservación según la riqueza y el valor de conservación de cada taxón. La riqueza de especies en Santa Fe aumenta con la disminución de la latitud y longitud en relación con un gradiente de aumento de temperatura y precipitaciones anuales promedio. En consecuencia las celdas ubicadas en el extremo nordeste poseen la mayor riqueza (conteniendo 84 % de las especies y las celdas ubicadas en el extremo suroeste la menor riqueza (20 %. Todas las celdas atravesadas por el río Paraná tienen una mayor riqueza que las celdas contiguas, probablemente, debido al efecto de este río como corredor de especies tropicales y subtropicales. Se definieron cinco áreas de endemismos, cuatro de ellas coinciden con una o dos divisiones fitogeográficas y son relevantes en análisis de conservación por tener especies exclusivas. El análisis de similitud entre celdas muestra tres grupos mayores, "noroeste", "noreste-centro" y "sur", que coinciden con tres áreas de endemismos. El análisis conjunto

    The purpose of the present study was to investigate the potential associations of binge drinking detected at the exit of nightclubs and risk behaviors and alcohol effects just after leaving the venue in a representative sample of Brazilian nightclub patrons according to sex. For this purpose, a portal survey study called Balada com Ciência was conducted in 2013 in the megacity of São Paulo, Brazil, using a two-stage cluster sampling survey design. Individual-level data were collected in 2422 subjects at the entrance and 1822 subjects at the exit of 31 nightclubs, and breath alcohol concentration (BrAC) was measured using a breathalyzer. The following day, 1222 patrons answered an online follow-up survey that included questions about risk behaviors and alcohol effects practiced just after leaving the nightclub. Weighted logistic regressions were used to analyze binge drinking associated with risk behaviors by sex. For both sexes, the most prevalent risk behaviors practiced after leaving a nightclub were drinking and driving (men=27.9%; women=20.4%), the use of illicit drugs (men=15.8%; women=9.4%) and risky sexual behavior (men=11.4%; women=6.8%). The practice of binge drinking increased the behavior of illicit drug use after leaving the nightclub by 2.54 times [95% CI: 1.26-5.09] among men who drank and increased the risk of an episode of new alcohol use by 5.80 times [95% CI: 1.50-22.44] among women who drank. Alcoholic blackouts were more prevalent among men [OR=8.92; 95% CI: 3.83-20.80] and women [OR= 5.31; 95% CI: 1.68-16.84] whose BrAC was equivalent to binge drinking compared with patrons with a lower BrAC. Public policies aiming to reduce patrons’ BrAC at the exit of nightclubs, such as staff training in responsible beverage service and legislation to prevent alcohol sales to drunk individuals, would be useful to protect patrons from the risk behaviors associated with binge drinking in nightclubs.

    The objective of this article is to describe the recent space and furniture utilization study conducted through direct observation at the small, academic-centered Schusterman Library. Student workers from the library's reference desk monitored two semesters of use and went on to observe a third semester after electrical power upgrades were installed. Extensive use details were collected about where library patrons sat during which parts of the day, and certain areas of the library were ultimately identified as much more active than others. Overall, the information gathered proved useful to library planning and will be valuable to future space initiatives. This article further demonstrates feasible means for any library to implement a similar study with minimal resources.

    Full Text Available The patterns of current land use in the Rabanal paramo suggest a slow and progressive deterioration of the vegetation of this ecosystem, probably due to the current practice of disturbances imposed apparently largely by human causes, mainly the expansion of the agricultural frontier (mechanized potato crops and grazing. The typical situation of the pattern of occupation and land-holding in these places, as well as the established production system, is the starting point to determine its effect on this sector of the Rabanal paramo ecosystem and define whether or not this fact is crucial to its conservation and management.The study was conducted in three stages that included the characterization of the area done through surveys, a review of primary and secondary education, followed by field work, and final tabulation of information.The present study obtained results which were intended to contribute to the knowledge of current land use in a sector of the settlement of San Antonio - Township Guachetá, bordering the Rabanal Paramo and with this give the necessary foundation for understanding how anthropogenic intervention operates in the area and its implications for vegetation dynamics and knowledge of its production systems.

    In this work the results obtained when analyzing new strategies in the reload designs of nuclear fuel and models of control bars, for boiling water reactors are presented. The idea is to analyze the behaviour of the reactor during an operation cycle, when the heuristic rules are not used (commonly used by expert engineers in both designs). Specifically was analyzed the rule of low leak and the load strategy Control Cell Core for the design of a fuel reload. In a same way was analyzed the rule of prohibiting the use of the intermediate positions in the control bars, as well as the construction of bar models based on load strategies type Control Cell Core. In the first analysis a balance and transition cycle were used. For the second analysis only a transition cycle was used, firstly with the reloads designed in the first analysis and later on with reloads built by other methods. For the simulation of the different configurations proposed in both cases, was used the code Simulate-3. To obtain the designs in both studies, the heuristic techniques or neural networks and taboo search were used. The obtained results show that it can be omitted of some rules used in the ambit for the mentioned designs and even so to obtain good results. To carry out this investigation was used Dell work station under Li nux platform. (Author)

    In the present work we characterized samples of plasters and pictorial layers taken from a fresco in the Acireale Cathedral. The fresco represents the Coronation of Saint Venera, patron saint of this Ionian town. By performing a detailed spectroscopic analysis of the plaster preparation layer by Fourier-transform infrared (FTIR) spectroscopy and x-ray diffraction (XRD), and of the painting layer by FTIR and confocal Raman microspectroscopy, scanning electron microscopy+energy dispersive x-ray spectroscopy, and XRD, we were able to identify the pigments and the binders present. In particular, Raman investigation was crucial to the characterization of the pigments thanks to the high resolution of the confocal apparatus used. It is worth stressing that the simultaneous use of complementary techniques was able to provide more complete information for the conservation of the artifact we studied

    2011-10-01

    This exploratory study examines the nature of customer entitlement and its impact on front-line service employees. In an open-ended qualitative inquiry, 56 individuals with waitstaff experience described the types of behaviors entitled customers engage in and the kinds of service-related "perks" these individuals feel deserving of. Participants explained how they responded to entitled customers, how and when managers became involved, and how their dealings with these patrons influenced their subjective physical and psychological well-being. We found that the behaviors of entitled customers negatively impacted waitstaff employees. Participants reported physiological arousal, negative affect, burnout, and feelings of dehumanization as a result of dealing with these patrons. While respondents drew on a variety of strategies to manage their encounters with entitled customers, they indicated workplace support was often informal and described feeling abandoned by management in dealing with this workplace stressor. Approaching customer entitlement as a form of microaggression, we offer recommendations for practice and suggest new directions for future research. .

The great majority of Spanish language journals are official publications of Spanish medical societies which represent for their members an important channel for scholarly communication. The Spanish language journals revealed a notable number of Spanish research groups (n = 525, 85.8 % of published papers came from health care institutions, and the prevalent type of collaboration was domestic and regional. Furthermore, the study reveals that higher levels of citation are associated with papers published by the aforementioned research groups, those having a greater degree of collaboration, and those that had at least one woman participating. On the other hand, English language journals are focused on basic research and only publish articles or reviews. Their productivity rate is lower, but they have a higher level of international participation and outstanding citation rates. 87.62 % of papers from these journals were published by researchers from academic institutions. Collaboration on the international level ranges between 16 % and 22 % of the total.

    Full Text Available Using multivariate analyses of fish community and environmental data, we explored associations among 13 fish species and 9 ecological guilds and identified ecological gradients that explain patterns in the fish community of the La Antigua River (Veracruz, Mexico. Altitude, distance to ocean, stream width, and water temperature were the most important variables explaining community composition. Sites with high altitudes (> 1 393 m, cold water ( 100 km and less than 5 m wide were dominated by non-native Onchorhynchus mykiss. Many sites exclusively inhabited by native poeciliids were also narrow ( 80 km, 20°C. Because 7 guilds were exclusive to a single species, results from the guild analysis were very similar to species-specific analyses. Higher species and guild diversity were found in wider sites (> 5 m, sites with lower altitudes (Utilizamos datos de la comunidad de peces y de variables ambientales y análisis multivariados para explorar asociaciones entre 13 especies y 9 gremios ecológicos en el río La Antigua (Veracruz, México.

The températe evergreens Nothofagus nítida and N. dombeyi are differentially distributed on soil moisture gradients, only the former being common on poorly-drained sites. We compared the relative height growth rate (RGR H and foliage loss of seedlings subjected experimentally to normal drainage (soil at field capacity, sudden waterlogging and gradual waterlogging for two months to determine which waterlogging regime more accurately predicts interspecific differences in tolerance, as evident from natural distributions. RGR H was similar between species but differed between treatments (normal watering > gradual waterlogging = sudden waterlogging. Sudden waterlogging caused massive foliage loss in the two species, but gradual waterlogging caused much greater foliage loss in N. dombeyi than in N. nítida, indicating some degree of acclimation by the latter species. Linear regressions indicated that RGR H was negatively affected by foliage loss in both species, without differences between them. Since no difference in RGR H was found between species in the waterlogging treatments, but yet in foliage loss, other mechanisms may be in volved in the short term growth reduction of N. nítida. Effects of waterlogging on long-term performance in the field were evaluated by reciprocal transplants between a poorly-drained site naturally occupied by N. nítida, and a well drained site naturally occupied by N. dombeyi. After two growing seasons, N. dombeyi had significantly lower specific leaf área (SLA and RGR H, at the poorly drained site than at its original site. At the poorly drained site N. nítida achieved 100 % survival, compared with 73.5 % in N. dombeyi. Reduced growth and survival of N. dombeyi associated with the negative effects on carbón gain of extensive foliage loss and reduced SLA may thus exelude it from the wetter sites. We conclude that tolerance may be better

    Full Text Available In order to evaluate the present distribution patterns of salmonids and their potential effects on native fish, we sampled 11 large lakes and 105 streams, encompassing a total of 13 main hydrographic watersheds of southern Chile (39° to 52°S. Overall, trout (Salmo trutta and Oncorhynchus mykiss accounted for more than 60 % of total fish abundance and more than 80 % of total biomass, while 40 % of the streams sampled did not have native fish. Salmon, introduced for aquaculture, such as O. kisutch, Salmo salar, and O. tshawytscha, were only present in lakes with salmon farming and did not seem to be reproducing naturally in affluent streams. We tested the effect of river geographic origin (Andes mountains, central valley, or Coastal range on fish abundance and found that rainbow trout was more restricted to the Andean streams with higher water discharge, while brown trout was widely distributed and did not relate to any of several catchment attributes measured. The abundance of native fish was greater in lakes than in streams and the highest native fish biodiversity occurred in streams of the central valley. The most common native species were Galaxias maculatus, G. platei, Brachygalaxias bullocki, Aplochiton zebra and Basilichthys australis. Streams with higher conductivity, larger pool areas, more fine sediments, and low brown trout densities were more suitable for native fish. Thus, catchments with higher anthropogenic disturbance appeared as refuges for native species. Given the descriptive nature of our study we can only presume the negative impacts of trout and salmon on native fish; an effect which should be superimposed on biogeographical conditioning of present distribution. Yet based on the present abundance and distribution patterns of salmonids and native fish, negative effects are very likely.

    2008-12-01

    Full Text Available This article addresses the role of private foundations in commissioning site-specific ephemeral art works: contemporary art projects of a temporary nature that are realised outside of public institutions. Though small in number, I argue that the private individuals creating and managing private foundations of this nature demonstrate a new form of patronage, creating in the process a new role of ‘curator/patron’. Equally, this process of realisation reflects the changing needs of contemporary art practice. Work of this scale and ambition would increasingly not be possible without the vision, perseverance and funding of these kinds of foundation. In Australia, this trend is demonstrated by two foundations: Kaldor Art Projects, and their commissioning of works by artists such as Christo and Jeanne-Claude, Gilbert & George and Jeff Koons; and the more recently formed Sherman Contemporary Art Foundation, whose first project was with Chinese artist Ai Weiwei. In this article, these examples are placed within the broader international context of foundation models such as Artangel, UK, Fondazione Nicola Trussardi, Milan, and The Public Art Fund, New York.

    Full Text Available The aim of this study was to delimit two Iodophanus species: I. carneus and I. testaceus , based on morphological characteristics and electrophoretic patterns of their intracellular isozymes. Twenty monosporic strains were used, including five belonging to I. granulipolaris as a control. Fourteen isozyme systems were tested, and the five having the best resolution selected: aspartate aminotransferase, esterases, alkaline phosphatase, glutamate dehydrogenase, and superoxide dismutase. These analyses confirmed the similarity between I. carneus and I. testaceus , since they both produced the same band patterns, which were in turn different from the band pattern of I. granulipolaris. So, as we couldn´t find any character wich permit us to classify the isolated studied during this work in defferent species, we believe that I. testaceus shoul be consider as a synonym of I. carneus .El objetivo del presente trabajo fue la delimitación taxonómica de dos especies del género Iodophanus : I. carneus e I. testaceus a partir de caracteres morfológicos y de los patrones electroforéticos de isoenzimas intracelulares. Para ello se utilizaron veinte cepas monospóricas, cinco de las cuales pertenecientes a I. granulipolaris que fueron utilizadas como control. Se probaron catorce sistemas isoenzimáticos y se eligieron los cinco con mejor resolución: aspartato amino transferasa, esterasa, fosfatasa alcalina, glutamato dehidrogenasa y superóxido dismutasa. El análisis de los patrones isoenzimáticos corroboró la silimitud existente entre I. carneus e I. testaceus , ya que los patrones de bandas obtenidas para estas dos especies fueron iguales y diferentes de I. granulipolaris. Entonces, al no encontrar ningún caracter que nos permita separar a los aislamientos estudiados en este trabajo en dos especies distintas, proponemos a I. testaceus como un sinónimo de I. carneus.

    The purpose of the Health Sciences Library System (HSLS) electronic book (e-book) study was to assess use, and factors affecting use, of e-books by all patron groups of an academic health sciences library serving both university and health system-affiliated patrons. A web-based survey was distributed to a random sample (n=5,292) of holders of library remote access passwords. A total of 871 completed and 108 partially completed surveys were received, for an approximate response rate of 16.5%-18.5%, with all user groups represented. Descriptive and chi-square analysis was done using SPSS 17. Library e-books were used by 55.4% of respondents. Use by role varied: 21.3% of faculty reported having assigned all or part of an e-book for class readings, while 86% of interns, residents, and fellows reported using an e-book to support clinical care. Respondents preferred print for textbooks and manuals and electronic format for research protocols, pharmaceutical, and reference books, but indicated high flexibility about format choice. They rated printing and saving e-book content as more important than annotation, highlighting, and bookmarking features. Respondents' willingness to use alternate formats, if convenient, suggests that libraries can selectively reduce title duplication between print and e-books and still support library user information needs, especially if publishers provide features that users want. Marketing and user education may increase use of e-book collections.

Some of the studied species are endemic to Turkey. The seed oils of different Leguminous taxa contained linoleic, oleic and linolenic acids as their major components. The ratios of these fatty acids in the Leguminous genera were found to be highly variable. Palmitic and stearic acids are the major saturated fatty acids in the seed oils. Vicia and Onobrychis patterns showed high similarity in means of qualitative fatty acid concentration. The tocopherol and tocochromanol patterns of the seed oils were also found to be highly variable among the genera investigated here. The total tocopherols was higher than the total tocotrienols. Alpha and gamma tocopherols were also the highest tocopherols present in the whole species. Beta, gamma and delta-tocotrienols were not found in most of the studied leguminous patterns.

    Full Text Available Abstract Background Alcohol intoxication and overserving of alcohol at sporting events are of great concern, given the relationships between alcohol consumption, public disturbances, and violence. During recent years this matter has been on the agenda for Swedish policymakers, authorities and key stakeholders, with demands that actions be taken. There is promising potential for utilizing an environmental approach to alcohol prevention as a strategy to reduce the level of alcohol intoxication among spectators at sporting events. Examples of prevention strategies may be community mobilization, Responsible Beverage Service training, policy work, and improved controls and sanctions. This paper describes the design of a quasi-experimental control group study to examine the effects of a multi-component community-based alcohol intervention at matches in the Swedish Premier Football League. Methods A baseline assessment was conducted during 2015 and at least two follow-up assessments will be conducted in 2016 and 2017. The two largest cities in Sweden are included in the study, with Stockholm as the intervention area and Gothenburg as the control area. The setting is Licensed Premises (LP inside and outside Swedish football arenas, in addition to arena entrances. Spectators are randomly selected and invited to participate in the study by providing a breath alcohol sample as a proxy for Blood Alcohol Concentration (BAC. Actors are hired and trained by an expert panel to act out a standardized scene of severe pseudo-intoxication. Four types of cross-sectional data are generated: (i BAC levels among ≥ 4 200 spectators, frequency of alcohol service to pseudo-intoxicated patrons attempting to purchase alcohol at LP (ii outside the arenas (≥200 attempts and (iii inside the arenas (≥ 200 attempts, and (iv frequency of security staff interventions towards pseudo-intoxicated patrons attempting to enter the arenas (≥ 200 attempts.

    Full Text Available La presencia del dinoflagelado tóxico Alexandrium catenella en las aguas interiores de la Patagonia noroccidental, fue registrada en la década de los 90. A partir de 1995 se iniciaron programas de monitoreo de fitoplancton orientados al seguimiento de este dinoflagelado y sus efectos sobre los mariscos en la Décima y Undécima Región de Chile, financiados por distintas instituciones. Esto permitió recolectar una importante base de datos, aunque incompleta en muchos aspectos debido a la independencia de objetivos de los diferentes estudios. En esta revisión se agruparon todos los datos disponibles para buscar patrones que ayuden a la formulación de hipótesis sobre la dispersión e incidencia espacial y temporal de A. catenella en esta amplia zona y mucho más habitada que la Duodécima Región. Inicialmente se recolectaron muestras mensuales y desde fines de 2000 semanales tanto de fitoplancton como de mariscos en un número de estaciones que varió cada año. Desde fines de 1995 al 2002 se registraron cuatro floraciones de A. catenella, con intensidad y distribución variable, observándose una expansión de la distribución geográfica de esta especie hacia el norte (desde aproximadamente 45° 47' S en 1996 a 42° S, Chiloé en 2002. Las cuatro floraciones registradas fueron marcadamente estacionales, concentradas entre los meses de enero a marzo y coincidieron con los máximos registros del veneno paralizante de los mariscos.

El analisis de los datos comprendio las estimaciones de cloruros en las descargas totales, temperaturas de yacimiento, exceso de vapor en los fluidos de alimentacion, las concentraciones de CO{sub 2} en las descargas totales y en la fase liquida del yacimiento y las saturaciones de liquido en la formacion. Con los resultados se elaboraron mapas de isovalores de los parametros mencionados correspondientes a 2006 y 2007 para investigar su evolucion con respecto a los mapas obtenidos en 2005, asi como su relacion con las historias de reinyeccion. Se correlacionaron las composiciones isotopicas de los fluidos incluyendo los de reinyeccion para estimar efectos de mezcla de fluidos. Los resultados indican que las variables estudiadas responden a las tasas de reinyeccion en el campo. Las relaciones {delta}D vs {delta}18 O indican que un buen numero de pozos del campo producen diferentes proporciones de retornos de reinyeccion; en la zona norte los pozos AZ-65D, AZ-13, AZ-32, AZ-9A, AZ-9AD, AZ-28A, AZ-69D y AZ-44 producen una mayor proporcion mientras que los pozos AZ-5, AZ-28 y AZ-19 entre otros, producen una menor proporcion. En la zona sur los pozos AZ-2A, AZ-16AD, AZ-46 y AZ-33 producen relativamente altas proporciones de retornos de reinyeccion mientras que los pozos AZ-34, AZ-36 y AZ-37 producen menores proporciones. La distribucion de saturaciones de liquido hallada en 2007 muestra que las areas de maxima saturacion han disminuido con respecto a las distribuciones de este parametro en 2005 y 2006. En 2007 las saturaciones maximas de liquido se localizaron alrededor de los pozos AZ-22 y AZ-23 (zona sur) y AZ-28, AZ-32, AZ-45 y AZ-48 (zona norte), mientras que las saturaciones minimas se localizaron en

    Full Text Available While «pattern-welded» swords have been found all over Europe from sites dating from the Migration Period and into the Early Middle Ages, they were steadily supplanted during the Viking period by swords made out of a few pieces of iron and steel, or even a single piece of steel. Swords with «Ulfberht» or related inscriptions were the most famous of these. The results of the metallurgical study of 44 specimens from «Ulfberht» swords, as well as some other Viking-age swords, together with electron microanalyses carried out on selected examples, are presented here.

    Mientras que se han encontrado en toda Europa espadas forjadas mediante el sistema de ‘pattern welding’ (entrelazado de láminas formando patrones visibles, procedentes de yacimientos que se extienden desde el Periodo de las Migraciones bárbaras hasta la Alta Edad Media, durante el periodo vikingo fueron habitualmente reemplazadas por espadas forjadas a partir de unas pocas piezas de hierro y acero, o incluso de una única pieza de acero. Las más famosas de entre ellas fueron las espadas con la inscripción «Ulfbehrt» u otras relacionadas. Este artículo presenta los resultados del estudio metalúrgico de 44 ejemplares de espadas de «Ulfberht» y otras de época vikinga, así como los microanálisis efectuados sobre algunas muestras seleccionadas.

    Full Text Available Physicochemical properties like density, viscosity, boiling point, saponification value (SV, iodine value (IV,and peroxide value (PV of Corn and Mustard oils were studied to evaluate the compositional quality of oils and also to investigate the effect on the use of same oil for repeated frying as it ultimately changes the physicochemical, nutritional and sensory properties of the oil. FT-IR spectroscopy was used to evaluate the degree of oxidation after heating and frying processes. Results revealed that due to the temperature change in the oil there is a notable difference in the spectral band which showed that the proportions of the fatty acids were changed. The spectra of Corn oil at the boiling point and at multiple frying times with a piece of potato showed frequencies in range of 2852.7–2926.0 cm−1 while in Mustard oil an additional peak was observed at 3633.8 cm−1 which exhibits the secondary oxidized product formation.

    In 1986, a report of the U.S. Surgeon General concluded that second hand smoke is a cause of disease in healthy non smokers. Subsequent many nations including Tunisia implement smoke-free worksite regulations. The aim of our study is to test air quality in indoor ambient air venues in Tunisia. A TSI SidePak AM510 Personal Aerosol Monitor was used to sample, record the levels of respirable suspended particles (RSP) in the air and to assess the real-time concentration of particles less than 2.5 microm in micrograms per cubic meter, or PM2.5. Thirty three venues were sampled in Tunis. The venues were selected to get a broad range of size, location and type of venue. Venues included restaurants and cafés, bars, bus stations, hospitals, offices, and universities. The mean level of indoor air pollution was 296 microg/m3 ranged from 11 microg/m3 to 1,499 microg/m3. The level of indoor air pollution was 85% lower in venues that were smoke-free compared to venues where smoking was observed (ppollution were found in hospitals, offices and universities (52 microg/m3) and the highest level was found in a bar (1,499 micro/m3). Hospitality venues allowing indoor air smoking in Tunisia are significantly more polluted than both indoor smoke-free sites and outdoor air in Tunisia. This study demonstrates that workers and patrons are exposed to harmful levels of a known carcinogen and toxin. Policies that prohibit smoking in public worksites dramatically reduce second hand smoke exposure and improve worker and patron health.

    Objectives: The purpose of the Health Sciences Library System (HSLS) electronic book (e-book) study was to assess use, and factors affecting use, of e-books by all patron groups of an academic health sciences library serving both university and health system–affiliated patrons. Methods: A web-based survey was distributed to a random sample (n = 5,292) of holders of library remote access passwords. A total of 871 completed and 108 partially completed surveys were received, for an approximate response rate of 16.5%–18.5%, with all user groups represented. Descriptive and chi-square analysis was done using SPSS 17. Results: Library e-books were used by 55.4% of respondents. Use by role varied: 21.3% of faculty reported having assigned all or part of an e-book for class readings, while 86% of interns, residents, and fellows reported using an e-book to support clinical care. Respondents preferred print for textbooks and manuals and electronic format for research protocols, pharmaceutical, and reference books, but indicated high flexibility about format choice. They rated printing and saving e-book content as more important than annotation, highlighting, and bookmarking features. Conclusions: Respondents' willingness to use alternate formats, if convenient, suggests that libraries can selectively reduce title duplication between print and e-books and still support library user information needs, especially if publishers provide features that users want. Marketing and user education may increase use of e-book collections. PMID:21753914

    The proportion of women who patronized traditional birth attendants (TBAs) or modern health care practitioners (MHCPs) was compared, including reasons for their choices. A comparative design was adopted to study 300 respondents selected through a multistage systematic random sampling technique. The instrument for data collection was a validated 21-item structured questionnaire. We observed that 75 (25%) patronized and 80 (27%) preferred TBAs, and 206 (69%) patronized and 220 (75%) preferred MHCPs, while 19 (6%) patronized both. The view that TBAs prayed before conducting deliveries was supported by a majority 75 (94%) of the respondents who preferred them. Factors associated with preference for TBAs should be addressed.

    Full Text Available Objective: To synthesize research findings on experiences and attitudes about obesity and stigma in health care. Methods: We compiled qualitative studies and applied Noblitt & Hare's meta ethnography to identify, translate, and summarize across studies. Thirteen qualitative studies on experiences and attitudes about obesity and stigma in health care settings were identified and included. Results: The study reveals how stigmatizing attitudes are enacted by health care providers and perceived by patients with obesity. Second-order analysis demonstrated that apparently appropriate advice can be perceived as patronizing by patients with obesity. Furthermore, health care providers indicate that abnormal bodies cannot be incorporated in the medical systems—exclusion of patients with obesity consequently happens. Finally, customary standards for interpersonal respect are legitimately surpassed, and patients with obesity experience contempt as if deserved. Third-order analysis revealed conflicting views between providers and patients with obesity on responsibility, whereas internalized stigma made patients vulnerable for accepting a negative attribution. A theoretical elaboration relates the issues of stigma with those of responsibility. Conclusion: Contradictory views on patients’ responsibility, efforts, knowledge, and motivation merge to internalization of stigma, thereby obstructing healthy coping and collaboration and creating negative contexts for empowerment, self-efficacy, and weight management. Professionals need to develop their awareness for potentially stigmatizing attitudes towards vulnerable patient populations.

    A full-scale mechanical prototype line was deployed to a depth of 2500 m to test the leak tightness of the electronics containers and the pressure-resistant properties of an electromechanical cable under evaluation for use in the ANTARES deep-sea neutrino telescope. During a month-long immersion study, line parameter data were taken using miniature autonomous data loggers and shore-based optical time domain reflectometry. Details of the mechanical prototype line, the electromechanical cable and data acquisition are presented. Data taken during the immersion study revealed deficiencies in the pressure resistance of the electromechanical cable terminations at the entry points to the electronics containers. The improvements to the termination, which have been integrated into subsequent detection lines, are discussed. The line also allowed deep-sea acoustic measurements with a prototype hydrophone system. The technical setup of this system is described, and the first results of the data analysis are presented.

    Patrons of art galleries and museums, tourists visiting historic buildings, and sightseers viewing archaeological sites are generally unaware of the extent to which science and technology has contributed to the value of what they see. Many countries rely on cultural tourism to generate national wealth. The use of radiation of many kinds to assist in the conservation/restoration of cultural heritage artefacts is described in this paper. In particular, the paper will describe studies of the pigments used in historic Australian Indigenous art, the degradation of manuscripts written using iron-gall inks, the protection of statues against corrosion and the selection of lubricants for use in old machinery. - Highlights: • We describe a diverse range of techniques used to study cultural heritage artefacts. • IR X-ray and particle beam techniques were used to study: • The structure and composition of Australian Indigenous bark paintings. • The effects of iron-gall inks on parchment. • The results of corrosion and corrosion protection in machinery and vehicles.

    Nowadays in the National Institute of Nuclear Research are carried out studies with some bio-inspired optimization techniques to improve the performance of the fuel cycles of the boiling water reactors of the Laguna Verde power plant (CLV). In the present work two bio-inspired techniques were applied with the purpose of improving the performance of a balance cycle of 18 months developed for the CLV: genetic algorithms (AG) and systems based on ants colonies (SCH). The design of the reference cycle it represents in several aspects an optimal cycle proposed starting from the experience of several operation decades with the boiling water reactors (BWR initials for Boiling Water Reactor) in the world. To try to improve their performance is beforehand a difficult challenge and it puts on test the feasibility of the optimization methods in the reloads design. The study of the bio-inspired techniques was centered exclusively on the obtaining of the control rod patterns (PBC) trying to overcome the capacity factor reached in the design of the reference cycle. It was fixed the cycle length such that the decrease of the coast down period would represent an increase of the capacity factor of the cycle; so that, it diminishes the annual cost associated with the capital cost of the plant. As consequence of the study, was found that the algorithm based on the ants colonies reaches to diminish the coast down period in five and half days respect to the original balance cycle, what represents an annual saving of $US 74,000. Since the original cycle was optimized, the above-mentioned, shows the ability of the SCH for the optimization of the cycle design. With the AG it was reach to approach to the original balance cycle with a coast down period greater in seven days estimating an annual penalization of $US 130,000. (Author)

    Full Text Available Thisstudy generally aimed to document the existing practice of the “Parada ng Lechon” in Balayan, Batangas Philippines to honor St. John the Baptist and the implications of the findings in relation to the study of Philippine culture. This paper employed the ethnographic research method which involved the use of documentary materials, participant observation method, questionnaires, and interviews with 150 purposively selected respondents. The results of the study revealed the world-famous “Parada ng Lechon” which originated as an old thanksgiving custom of the working class in what-used-to-be the poor and depressed area of the western district of Balayan, Batangas, Philippines. It was noteworthy to mention that during the Spanish and American regimes, families who were fortunate enough to receive some significant blessings during the past year would parade a lechon in the town plaza every June 24 - the Feast of St. John the Baptist. For the Balayeños, the parading of lechon is the best expression of thanksgiving and veneration to their patron saint. Even during these times, the sight of people parading lechons in Balayan - coupled with centuries-old practice of water dousing - was quite a spectacle to behold. The “Parada ng Lechon” is considered an invaluable asset that encapsulates the Philippine culture which may be cherished for posterity.

    Full Text Available Patterns of habitat preference and distribution and abundance of wintering bird fauna in central Spain. Analysis and prediction of the effect of ecological factors This paper analyses the effect of geographic, topographic, land use and habitat structure variables on the composition and structure of wintering bird communities in Central Spain (Iberian peninsula. Parameters describing the avifauna varied in a predictable way considering a small group of coarse-grained variables defining the geographical and altitudinal location of the censuses, and the basic characteristics of the structure and typology of habitats: 49-76% of variance accounted for total bird density and for abundance of four ecological groups, 37-63% accounted for species richness and diversity, and 65% explained the relative abundance of species with conservation problems according to the European scale (SPEC figures. Regarding the most widespread species in the study area, significant models were obtained by means of tree regression analysis for 50 species, with an average reduction of deviance of 39%. Altitude was the most important variable affecting bird community parameters and abundance of each bird species, showing a consistent and marked negative effect. Structural complexity of the vegetation and geographical location followed as the variables of importance explaining variability. The habitats with the lowest bird density, richness and diversity of birds were mountain grasslands/shrublands, young pine re-forestations, and Pyrenean oak forests at 1,200-1,600 m a.s.l. The habitats with the highest values on these parameters were riparian forests, agricultural mosaics, and holmoak “dehesa” parklands, mainly located at the southern and western part of the region and at intermediate altitudes. The total density of birds increased from east to west, was higher in intermediate altitudes than in the extremes of the altitudinal range, and increased with habitat structural

    The {sup 131}I prepared as potassium iodide (KI) or sodium iodide (NaI) is given to patients to treat some diseases related to the thyroid gland, in doses of 15 to 30 mCi for hyperthyroidism and 100 to 300 mCi in treatments of thyroid cancer. Up to 80% of the administered activity is discarded by the patient through the body fluids over a period of 24 h; these radioactive waste must be controlled and accordingly the different countries based on radiological impact studies establishing maximum release rates. In Colombia, the Resolution 180005 2010 establishes 1000 Bq/day (2.7027x10{sup -5} Ci /day), 10000 Bq/month (2.7027x10{sup -4} mCi/month) or 100000 Bq/year (2.7027x10{sup -3} mCi/year), this restriction requires implementing waste management methods generated by patients before discharge to the sewage networks. The method of retention of these wastes through tanks, without any treatment generates a high potential risk, therefore, this study shows three alternatives to remove the {sup 131}I in the amount of waste liquids, to generate a small solid residue in secure containers, allowing pouring fluids with radioactive traces without exceeding the limits. The sizing of the system applicable to nuclear medicine services depends on the workload of the service and combines the three methods described here by a control system, which does not require the direct intervention of staff, optimizing safety and radiation protection in the service.

    To describe the radiological features of pulmonary tuberculosis (TB) in patients infected with human immunodeficiency virus (HIV) and its correlation with the blood CD4 cell count. We present 44 HIV+patients, 24 with CD4 cell counts of less than 200 cells/mm''3 (group A) and 20 in whom the CD4 counts surpassed this level (group B). We also assessed the chest x-ray images to determine whether or not there was any correlation with the blood CD4 cell counts. Fisher's exact test was used for the statistical study of the differences in the radiological findings in the two groups. The incidence of atypical features was significantly greater in the patients with CD4 cell counts of less than 200 cells/mm''3 (group A) than in those with CD4 counts of over 200 cells/mm''3 (group B). Among HIV+patients, those with a more intact immune status were more likely to present lung x-ray images typical of post-primary TB, with cavitary lesions in upper lobes. The group of patients in whom the immune deficiency was more marked showed a greater incidence of atypical pulmonary findings, more characteristics of primary TB. (Author)

    Higher-tier ecological risk assessment (ERA) in mesocosms is commonly performed in lotic or lentic experimental systems. These systems differ in their physico-chemical and hydrological properties, leading to differences in chemical fate, community characteristics and potential recovery. This raises the issue of the relevance and sensitivity of community-level endpoints in different types of mesocosms. In this study, macroinvertebrate abundance and biomass estimates were used to assess the effects of a dithiocarbamate fungicide, thiram (35 and 170 µg l(-1)), and a petroleum middle distillate (PMD; 0.01, 0.4, 2 and 20 mg l(-1)) in outdoor stream and pond mesocosms. Streams were continuously treated during 3 weeks followed by a 2-month long post-treatment period. Ponds were treated weekly for 4 weeks, followed by a 10-month long post-treatment period. Taxonomic structure of macroinvertebrate communities was characterized using the α, β and γ components of taxa richness, Shannon and Gini-Simpson indices. Computations were based either on abundance or biomass data. Results clearly highlighted that the effects of chemicals depended on the exposure regime (for thiram) and type of system (for the PMD). Causes of the differences between streams and ponds in the magnitude and nature of effects include differential sensitivity of taxa dwelling in lentic and lotic systems and the influence of hydrology (e.g., drift from upstream) and mesocosm connectivity on recovery dynamics. This study also showed complementarities in the use of both types of mesocosms to improve the characterization of chemical effects on communities in ERA.

    Full Text Available Abstract Juices and fruit nectars are an important segment of the beverage market in Brazil. The aim of this study was to analyze and characterize the profile of consumers of ready-to-drink juices and fruit nectars. A semi-structured questionnaire was applied to 389 patrons, intentionally and conveniently, when they approached the shelves. The chi-square test was applied to associate sociodemographic variables and consumption profile of the beverages with the type of establishment. Logistic regression models were developed to evaluate the variables associated with nectar acquisition. The level of education and knowledge about the beverages were significantly related. Practicality was the main reason that led respondents to consume these drinks, followed by quality and price, with the latter being associated with the level of education. Nectar was the most purchased option, and this choice was associated with increasing age and education, price and practicality. The consumption of juices and nectars with no added sugar was lower compared with traditional beverages. The information in the labels of these beverages was not sufficiently clear, for most of the participants. The most mentioned brand by the interviewed was the one with better sensory preference, regardless of flavour and the blinded or informed analysis.

    Full Text Available This study reports the infectious peritonitis rates in 44 patients on peritoneal dialysis in three different systems over the last 15 years, covering clinical outcomes, exit-site infections, tunnel infections, causative microorganisms, and the history of susceptibility of organisms causing peritonitis, in order to establish our center-specific selection of empiric therapy. Two microbiological procedures were herein used: method A, where 100 ml of dialysate were centrifuged and cultured in standard media and into blood-culture bottles; and method B, where 10 ml were directly injected into blood-culture bottles. Swabs from the exit-site or tunnel were taken when purulent drainage was observed. There were 96 episodes of peritonitis during 110.43 patient-years (0.87 episodes/patient-year. Sensitivity of method A was 96.88% (93/96 episodes versus 81.25% (78/96 of method B (p= 0.001. Gram stain sensitivity was 36.46%. The etiologic agents were 64 (56.64% gram-positive cocci, 22 (19.47% gram-negative fermentative rods, 20 (17.7% gram-negative non fermentative rods, 5 (4.43% yeasts, 1 (0.88% micelial fungus, and 1 (0.88% anaerobic rod. Fifty-five exit-site infections were documented (0.5 episodes/patient-year. Ceftazidime and imipenem showed excellent activity on gram-negative rods. There were 92.3% of methicillin-susceptible Staphylococcus aureus but only 33.3% of methicillin-susceptible coagulase- negative staphylococci; vancomycin was active against 100% of the gram-positive cocci. The clinical outcomes of peritonitis were 73 initial cure, 19 catheter removal and four related deaths. The empiric therapy in our center should be vancomycin plus ceftazidime or imipenem. Once the etiological agent and its susceptibility pattern are known, the deescalating therapy must be applied to avoid the emergence and spread of vancomycin-resistant microorganisms.Se comunican las tasas de peritonitis infecciosa de 44 pacientes en tres sistemas diferentes de di

    Some versions of restaurant menu labelling legislation do not require energy information to be posted on menus for drive-through lanes. The present study was designed to quantify the number of customers who purchase fast food through drive-in windows as a means of informing legislative labelling efforts. This was an observational study. The study took place at two McDonald's and Burger King restaurants, and single Dairy Queen, Kentucky Fried Chicken, Taco Bell and Wendy's restaurants. The number of customers entering the chain restaurants and purchasing food via the drive-through lane were recorded. A total of 3549 patrons were observed. The percentage of customers who made their purchases at drive-throughs was fifty-seven. The overall average (57 %) is likely a conservative estimate because some fast-food restaurants have late-night hours when only the drive-throughs are open. Since nearly six in ten customers purchase food via the drive-through lanes, menu labelling legislation should mandate the inclusion of menu labels on drive-through menu boards to maximise the impact of this public health intervention.

    We examined loose cigarette (loosie) purchasing behavior among young adult (aged 18-26 years) smokers at bars in New York City and factors associated with purchase and use. Between June and December 2013, we conducted cross-sectional surveys (n = 1916) in randomly selected bars and nightclubs. Using multivariable logistic regression models, we examined associations of loose cigarette purchasing and use with smoking frequency, price, social norms, cessation behaviors, and demographics. Forty-five percent (n = 621) of nondaily smokers and 57% (n = 133) of daily smokers had ever purchased a loosie; 15% of nondaily smokers and 4% of daily smokers reported that their last cigarette was a loosie. Nondaily smokers who never smoked daily were more likely than were daily smokers to have last smoked a loosie (odds ratio = 7.27; 95% confidence interval = 2.35, 22.48). Quitting behaviors and perceived approval of smoking were associated with ever purchasing and recently smoking loosies. Loosie purchase and use is common among young adults, especially nondaily smokers. Smoking patterns and attitudes should be considered to reduce loose cigarette purchasing among young adults in New York City.

    Full Text Available La interacción entre las organizaciones y la innovación son los dos ejes sobre los que giran las nuevas dinámicas productivas. El objetivo de este artículo es comprobar si existe un modelo o patrón común en la red de relaciones existentes entre las empresas innovadoras y de base tecnológica ubicadas en los parques tecnológicos españoles. Este objetivo implica estudiar la red que se conforma en dichos espacios tanto desde una perspectiva reticular, como de la búsqueda de un modelo explicativo. En dicho modelo nos apoyamos además, de en los atributos de las empresas, en las variables relacionales extraídas de los flujos entre las mismas. Aplicamos el modelo a las redes de tres Parques Tecnológicos, y de los resultados extraemos que la estructura de la red viene determinada, además de las variables consideradas, por la condiciones socioinstitucionales e industriales del área geográfica sobre la que se asientan.

    Full Text Available This article focuses on the ways in which a candidate running for city councilor and representing the Peronist party organized the distribution of public resources (social plans and food programs in La Matanza, a district in the west of Greater Buenos Aires, during the 2005 election campaign. The first part describes the personal trajectory of the candidate and some of the neighbors dependent on him. The second part examines how this leading figure rallied election campaigners and the meaning invested in their behaviors during a series of events including the opening of a 'soup kitchen' and the election day itself. The text also identifies the constraints imposed on these actors and the implications associated with their compliance (or failure to comply with mutual obligations. This analysis enables a clearer understanding of the dynamics and complexity of the processes regulating vast political circuits in which State resources are redistributed in exchange for votes on the outskirts of Greater Buenos Aires.
