The Police Executive and Governance: Adapting Police Leadership to an Increase in Oversight and Accountability in Police Operations

Directory of Open Access Journals (Sweden)

Gary Ellis

2014-03-01

Full Text Available In a democracy, it is generally understood that the police serve at the will of the people and are accountable through police governance. This usually consists of elected and/or appointed officials whose primary legal authority is to set policy and appoint the police leaders whom they hold accountable for ensuring that effective policing operations are carried out. It is widely held in common law jurisdictions that the governing body is limited in their role and cannot get involved in “operational policing issues.” In June 2010, the G20 world leaders’ conference was held in Toronto, Canada. The events surrounding the police actions during this conference caused a great deal of concern and led the Toronto Police Services Board, who are the governing authority for the Toronto Police Service, to commission a review to look at their own role. The findings in relation to “board” involvement in the operational side of policing challenged a long held belief regarding the limited role of governance in police operations. These findings will be examined in relation to the lack of board expertise and the challenges faced by police leaders to adapt and develop their attitudes, skills and abilities to respond to any expansion of governance authority.

Police as Life World. An Ethnography of Police-Officers' Identity

Directory of Open Access Journals (Sweden)

Rafael Behr

2002-01-01

Full Text Available The purpose of this paper is to present some findings and problems which I encountered during my ethnography work on several German police units conducted in 1995. Participant observation is not original, but nevertheless unusual for a study of police work. To understand the behavior and the thinking of police officers, one must regard their exclusive possession of power and their discretion for using it. The power of the police is different to the power of suspects or other individuals: Police-power is part of the monopolized state-force, the action of suspects against the police is seen as violence or obstruction. The tensions following this difference are both subject and background of stories and actions of police officers, especially for those "on the beat" (also called "street cops". The ethnography of police-work refers to the narrations of street cops and the observation of their attitudes for "managing the job". I argue, that in contrast to the official "police culture", it can also be referred to it as "cop culture". Cop culture is significantly connected with "doing masculinity".

Gastric emptying measurements: delayed and complex emptying patterns without appropriate correction

Energy Technology Data Exchange (ETDEWEB)

Moore, J.G.; Christian, P.E.; Taylor, A.T.; Alazraki, N.

1985-10-01

Anteriorly acquired and geometric mean corrected gastric emptying curves of solids and liquid isotopic-labeled meals were compared in 37 subjects given 61 meals of three different sizes. Anterior data alone consistently and significantly underestimated solid-phase gastric emptying rates with all meal sizes when compared to geometric mean acquired data. However, with liquids there were only slight differences between anterior and anterior and posterior geometric mean corrected emptying-rates. The difference probably reflects greater attenuation of the 140 kev photon of /sup 99m/Tc compared to the 247 keV photon of In. With anterior data alone, an apparent early delay in emptying of solids was present with all meal sizes and the resultant emptying curves were nonlinear in shape. Geometric mean correction resulted in the linearization of the solid-phase emptying curves and essentially eliminated the apparent delay in emptying or lag phase noted with the anterior data alone. Based on our results, geometric mean correction techniques are necessary for accurate assessment of radioisotopic-labeled solid meals.

Policing for Conflict Zones: What Have Local Policing Groups Taught Us?

Directory of Open Access Journals (Sweden)

Bruce Baker

2017-08-01

Full Text Available The police are invariably severely reduced or even cease to be active in times of conflict. Policing as an activity, however, persists, with local groups taking up the role of maintaining order and combating crime. Such local policing is very diverse in its practices and in the nature of its links with the state. Using examples of local policing practices in four sub-Saharan conflicts, this article considers different patterns of harnessing local capacity to provide policing services. The patterns range from authorities utilising existing local policing providers or initiating new local responses, to local non-government organisations [NGOs] seeking to fill policing gaps left by the state, or long-established local provision continuing unchanged. Each response, whether one of cooperation, delegation, neglect or abandonment, is evaluated for its effectiveness, and lessons to be learned from their practices are offered. Together the four case studies suggest new pathways to achieving police effectiveness and reform in challenging conflict environments.

Policing Diversity: Examining Police Resistance to Training Reforms for Transgender People in Australia.

Science.gov (United States)

Miles-Johnson, Toby

2016-01-01

Using field notes collected from participant observation of Australian police officers training to work with the transgender community, the current research builds on previous work examining social identity theory (Tajfel, 2010) to explain how one training program implemented to educate police about transgender people challenges police culture. This research determines that police culture, training procedures, and stereotypes of gender are equally influential on police perceptions of all transgender people. Overall, the results indicate that negative police perceptions toward police training reforms strengthen in-group identity of police, and negative out-group perceptions of transgender people.

Pathways to Police Contact for Spousal Violence Survivors: The Role of Individual and Neighborhood Factors in Survivors' Reporting Behaviors.

Science.gov (United States)

Barrett, Betty Jo; Peirone, Amy; Cheung, Chi Ho; Habibov, Nazim

2017-09-01

Rational choice theory proposes that spousal violence survivors engage in a cost-benefit analysis when determining whether to contact the police in the aftermath of violence. Feminist intersectional frameworks contend that the perceived costs and benefits of police intervention differ among survivors based on their intersecting social identities. Normative theory further posits that it is not solely individual factors but also social norms derived from one's neighborhood context that may be related to reporting practices. Consistent with these perspectives, this study assessed the association between spousal violence survivors' sociodemographic, violence, and neighborhood characteristics and (a) police contact, (b) pathways to police contact, (c) motivations for contacting the police, and (d) motivations for not contacting the police. Data were drawn from the 2009 Canadian General Social Survey-Victimization main file, and included male and female survivors ( N = 890). Survivors most commonly contacted the police to stop the violence (89.4%) and most commonly did not contact the police because they did not believe it was important enough (35.3%). Results of multivariate regression analysis indicate that survivors who were visible minority, those who feared for their lives, and those who were injured were significantly more likely to self-report violence to police. Survivors were more likely to say the violence was not important enough to report if there was a police station in their neighborhood, and were less likely to say that violence was not important enough to report if they had experienced multiple incidents of violence. Implications for policing and criminal justice system engagement with spousal violence survivors are provided.

Reporting Crime Victimizations to the Police and the Incidence of Future Victimizations: A Longitudinal Study.

Science.gov (United States)

Ranapurwala, Shabbar I; Berg, Mark T; Casteel, Carri

2016-01-01

Law enforcement depends on cooperation from the public and crime victims to protect citizens and maintain public safety; however, many crimes are not reported to police because of fear of repercussions or because the crime is considered trivial. It is unclear how police reporting affects the incidence of future victimization. To evaluate the association between reporting victimization to police and incident future victimization. We conducted a retrospective cohort study using National Crime Victimization Survey 2008-2012 data. Participants were 12+ years old household members who may or may not be victimized, were followed biannually for 3 years, and who completed at least one follow-up survey after their first reported victimization between 2008 and 2012. Crude and adjusted generalized linear mixed regression for survey data with Poisson link were used to compare rates of future victimization. Out of 18,657 eligible participants, 41% participants reported to their initial victimization to police and had a future victimization rate of 42.8/100 person-years (PY) (95% CI: 40.7, 44.8). The future victimization rate of those who did not report to the police (59%) was 55.0/100 PY (95% CI: 53.0, 57.0). The adjusted rate ratio comparing police reporting to not reporting was 0.78 (95%CI: 0.72, 0.84) for all future victimizations, 0.80 (95% CI: 0.72, 0.90) for interpersonal violence, 0.73 (95% CI: 0.68, 0.78) for thefts, and 0.95 (95% CI: 0.84, 1.07) for burglaries. Reporting victimization to police is associated with fewer future victimization, underscoring the importance of police reporting in crime prevention. This association may be attributed to police action and victim services provisions resulting from reporting.

Gastric-emptying tests

International Nuclear Information System (INIS)

Brown, M.L.; Malagelada, J.R.

1983-01-01

Mechanisms regulating gastric emptying have been characterized through many decades of experimental work. Both central and peripheral mechanisms are important. Central mechanisms are related to the center of vomiting and are probably influenced by psychologic and emotional factors. Peripheral mechanisms are located at both sides of the pylorus. Gastric mechanisms are stimulatory and are triggered mainly by distention of the stomach, although hormonal mechanisms may also participate (gastrin). However, with complex, nutrient-containing meals, the intragastric volume is not the primary determinant of gastric emptying. Inhibitory mechanisms of the gut are more important. The key factors are the pH, osmolality, and nutrient content of the chyme being emptied into the duodenum. Osmotic and pH-sensitive receptors are thought to reside in the duodenum. On the other hand, receptors triggered by nutrients extend much more distally into the duodenum and are sensitive to nutrient composition and load. Protein, carbohydrates, and lipids all inhibit gastric emptying, although the lipids are probably the most potent inhibitors. If the duodenal load or the characteristics of the emptying material are not adequate, inhibitory mechanisms will reduce gastric emptying at the expense of expanding the intragastric volume. It is therefore not possible to dissociate postprandial gastric emptying from postprandial gastric secretion

Diversity Policing–Policing Diversity: Performing Ethnicity in Police and Private-Security Work in Sweden

Directory of Open Access Journals (Sweden)

Cecilia Hansen Löfstrand

2014-09-01

Full Text Available This article draws upon two separate studies on policing in Sweden, both investigating “ethnic diversity” as a discourse and a practice in the performance of policing functions: one interview study with minority police officers from a county police authority and one ethnographic study of private security officers. To examine how “diversity policing” and the “policing of diversity” are performed by policing actors, their strategic reliance on an ethnically diverse workforce is examined. The official discourse in both contexts stressed “diversity policing” as a valuable resource for the effective execution of policing tasks and the legitimation of policing functions. There was, however, also another, more unofficial discourse on ethnicity that heavily influenced the policing agents’ day-to-day work. The resulting practice of “policing diversity” involved situated activities on the ground through which “foreign elements” in the population were policed using ethnicized stereotypes. Diversity in the policing workforce promoted the practice of ethnic matching, which, ironically, in turn perpetuated stereotypical thinking about Swedish “others”. A conceptual framework is developed for understanding the policing strategies involved and the disjuncture found between the widely accepted rationalities for recruiting an ethnically diverse workforce and the realities for that workforce’s effective deployment at the street level.

Perceived Threat Associated with Police Officers and Black Men Predicts Support for Policing Policy Reform

Directory of Open Access Journals (Sweden)

Allison Louise Skinner

2016-07-01

Full Text Available Racial disparities in policing and recent high-profile incidents resulting in the deaths of Black men have ignited a national debate on policing policies. Given evidence that both police officers and Black men may be associated with threat, we examined the impact of perceived threat on support for reformed policing policies. Across three studies we found correlational evidence that perceiving police officers as threatening predicts increased support for reformed policing practices (e.g., limiting the use of lethal force and matching police force demographics to those of the community. In contrast, perceiving Black men as threatening predicted reduced support for policing policy reform. Perceived threat also predicted willingness to sign a petition calling for police reform. Experimental evidence indicated that priming participants to associate Black men with threat could also reduce support for policing policy reform, and this effect was moderated by internal motivation to respond without prejudice. Priming participants to associate police officers with threat did not increase support for policing policy reform. Results indicate that resistance to policing policy reform is associated with perceiving Black men as threatening. Moreover, findings suggest that publicizing racially charged police encounters, which may conjure associations between Black men and threat, could reduce support for policing policy reform.

Temperament vs. chronic fatigue in police officers

Directory of Open Access Journals (Sweden)

Ewa Stępka

2015-12-01

Full Text Available Background: Chronic fatigue is a problem affecting a still growing number of people. Among them there are representatives of different professions who are forced to cope not only with occupational stress, but also with the problem of fatigue. The police is one of such occupational groups, in which exposure to stressful and often traumatic situations, contact with those who violate the law, shift work and contact with superiors can play a key role in the development of chronic fatigue. However, chronic fatigue, induced by the above mentioned factors, does not affect all police officers since its occurrence also depends on many personal traits, including temperament. Material and methods: We studied a group of 61 police officers of the Kuyavian-Pomeranian garrison. The study was conducted using the Buss and Plomin EAS (emotionality, activity, sociability Temperament Questionnaire, CIS-20R (community, innovation, survey Questionnaire, developed by Vercoulen et al. and a questionnaire on socio-demographic data. Results: The results indicated the relationship between chronic fatigue and emotionality. Statistical analyses showed a negative correlation between the nature of emotional components, distress, fear, anger, and the general rate of chronic fatigue. There was no statistically significant correlation between age, and service experience and the level of chronic fatigue. Conclusions: The results indicate that the officers of the study group show dramatically high levels of chronic fatigue. The results also revealed that temperament characteristics, such as sociability and activity, reported in the literature as factors reducing fatigue and stress, did not show relevance to chronic fatigue in the study group.

Attitudes in Korea toward Introducing Smart Policing Technologies: Differences between the General Public and Police Officers

HyungBin Moon

2017-10-01

Full Text Available This study analyzes different attitudes toward introduction of smart policing technologies in cybercrime policing among the Korean public and police. Policing is essential for a sustainable community. Technological advances in policing have both positive and negative aspects, making it essential to investigate perceptions of both public and police when introducing smart policing technologies. A discrete choice experiment was undertaken to survey preferences of the public and police toward introduction of such technologies and conduct simulation analysis to compare changes in the acceptance of various scenarios. The study divides cybercrime policing into prevention and investigation. The sample included 500 members of the public and 161 police officers. The results show that the public thinks an increase in yearly taxes and invasion of privacy are the most important factors. Conversely, the police think factors enhancing the efficiency of policing are most important. Moreover, when smart policing technologies are introduced, the public and police perceive more utility in the prevention and investigation of cybercrime, respectively. Few studies in this field separate the prevention and investigation of crimes, or compare perceptions of the public and police toward the introduction of smart policing technologies. This study’s quantitative analysis provides insights lacking in previous literature.

Commercial sex plays a critical role in rapidly increasing heterosexual transmission of HIV in China. Low-paid female sex workers (FSWs) are especially vulnerable to HIV/AIDS. Because of the illegality and stigma associated with sex work, FSWs may constantly live with fears in their daily life. Based on cross-sectional study of 794 low-paid FSWs in China we described their psychological fears related to commercial sex and examined the associations between fears and HIV-related behaviors. Fear of HIV infection was significantly associated with consistent use of condoms with clients. However, fear of breaching sex worker identity significantly prevented the FSWs from consistently using condoms with clients and taking HIV tests. Fear of being arrested by the police was positively associated with consistent use of condoms but negatively associated with accessing HIV prevention services. Our findings underlined the importance of examining the triadic interaction of behavioral, psychological and environmental factors in HIV prevention interventions among low-paid FSWs.

Gastric and oesophageal emptying in obesity

Energy Technology Data Exchange (ETDEWEB)

Maddox, A.; Horowitz, M.; Wishart, J.; Collins, P. (Royal Adelaide Hospital (Australia))

1989-01-01

Gastric and esophageal emptying were evaluated in 31 obese patients and 31 control subjects. A double-isotope techniques was used to measure gastric emptying of a mixed solid/liquid meal, and esophageal emptying was measured as the time taken for a bolus of the solid meal to enter the stomach. Gastric emptying of the solid and the liquid meal and esophageal emptying were delayed in the obese patients compared with the control subjects. There were no significant relationships among gastric emptying, esophageal emptying, and upper gastrointestinal symptoms in the obese patients alone. However, in the total group of 62 subjects there were significant correlations between body mass index and both gastric and esophageal emptying. These results indicate that delayed gastric and esophageal emptying occurs frequently in obesity and that these abnormalties relate to body weight.

Weight loss following gastroplasty had no correlation with gastric emptying rate. Patients who showed transient prolongation of gastric emptying returned to normal one year later and showed no significant difference in weight loss from those who did not have temporary delayed gastric emptying. Perhaps gatroplasty (at least temporarily) reduces the gastric volume producing early satiation without affecting the gastric emptying rate as tested by a small volume radiolabelled test meal. Longer follow-up is indicated to see if delayed weight gain occurs because of gastric pouch stretching and if this has any correlation with gastric emptying rate. (Author)

2016-05-01

Full Text Available Since the reformation and democratization movement in 1998, Indonesians have faced a chronic corruption problem. At the beginning of reformation era in 1998 to fight against corruption, the Indonesian government reforms the organization structure of the Indonesia Police to be an independent body separated from the Military organization. The police reforms begun in 1999 and got legal foundation with Act No. 2/2002. However, since fourteen years, the level of police reform has not yet succeed because of low community satisfaction on police service and the intense conflicts always occur whenever ACA investigates the case of corruptions conducted by police leaders. Three conflicts between police institution and ACA have taken placed. By using institutionalism approach, this research focus on the reform in police themselves are major actors on how reforms are organized and managed. This study is interpretative in nature gained only through social constructions such as language, consciousness, shared meanings, documents, tools, and other artefacts’. This finding revealed that this unsuccessful institutionalization process took place in a context of the main task of police for communicty service. Second, the study has demonstrated that three concepts from institutional theory as aforementioned provided vocabularies and insights to explain the phenomenon under study.

Empty Container Logistics

2012-05-01

Full Text Available Within the whole world container traffic, the largest share of containers is in the status of repositioning. Container repositioning results from the need for harmonization between the point of empty container accumulation and the point of demand, and waiting time for the availability of the first next transport of cargo. This status of containers on the container market is the consequence of imbalances in the worldwide trade distribution on most important shipping routes. The need for fast and effective reallocation of empty containers causes high costs and often represents an obstacle affecting the efficiency of port container terminals and inland carriers.In accordance with the above issue, this paper is mainly focused on the analysis of the data concerning global container capacities and the roots of container equipment imbalances, with the aim of determining the importance of empty container management and the need for empty container micro-logistic planning at the spread port area.

Gastric emptying abnormal in duodenal ulcer

Holt, S.; Heading, R.C.; Taylor, T.V.; Forrest, J.A.; Tothill, P.

1986-07-01

To investigate the possibility that an abnormality of gastric emptying exists in duodenal ulcer and to determine if such an abnormality persists after ulcer healing, scintigraphic gastric emptying measurements were undertaken in 16 duodenal ulcer patients before, during, and after therapy with cimetidine; in 12 patients with pernicious anemia, and in 12 control subjects. No difference was detected in the rate or pattern of gastric emptying in duodenal ulcer patients before and after ulcer healing with cimetidine compared with controls, but emptying of the solid component of the test meal was more rapid during treatment with the drug. Comparison of emptying patterns obtained in duodenal ulcer subjects during and after cimetidine treatment with those obtained in pernicious anemia patients and controls revealed a similar relationship that was characterized by a tendency for reduction in the normal differentiation between the emptying of solid and liquid from the stomach. The similarity in emptying patterns in these groups of subjects suggests that gastric emptying of solids may be influenced by changes in the volume of gastric secretion. The failure to detect an abnormality of gastric emptying in duodenal ulcer subjects before and after ulcer healing calls into question the widespread belief that abnormally rapid gastric emptying is a feature with pathogenetic significance in duodenal ulcer disease.

Objective: The relationship between gastroesophageal reflux disease (GERD) and gastric emptying rate was investigated. Results of endoscopy, 24-hour esophageal pH monitoring were also evaluated. Methods: 15 patients were evaluated with endoscopy, pH monitoring and radionuclide gastric emptying. The results were compared with that of 17 control subjects. Correlations of gastric emptying rate and esophagitis, 24-hour pH monitoring between GERD patients and control subjects were also analyzed. Results: Liquid gastric emptying rate of GERD patients was significantly lower than that of control subjects at 15 and 30 min (P 0.05), but there exhibited a linear correlation between 50% solid emptying time and esophagus pH total score (r=0.643, P<0.05). Conclusions: The results indicate a delayed liquid and solid gastric emptying in GERD patients. There is a linear correlation between 50% solid emptying time and esophagus pH total score. Delayed gastric emptying may be an important factor in the pathogenesis of GERD

The Potential Use of Legitimate Force for the Preservation of Order: Defining the Inherent Role of Public Police Through Policing Functions that cannot be Carried out by Private Police

Directory of Open Access Journals (Sweden)

Jasmina Arnež

2016-12-01

Full Text Available In the UK, private policing institutions have been rapidly increasing since the 1980s, so the lines between public- and private police have been blurred. This paper explores whether there is a policing function that is inherent in public police and if so, why it occupies this position. It integrates Rousseau’s social contract theory, Bittner’s definition of police functions, Brodeur’s reasoning on force and Loader and Walker’s concept of ‘policing as public good’ to argue that the potential use of legitimate force for the preservation of order is the function intrinsic to public police. It shows why it cannot and should not be carried out by private police and outlines how it depends on police legitimacy. It concludes with an abstract rethinking of public-state-police relations to determine that this function remains in the realm of public policing.

Designing Multidimensional Policing Strategy And Organization: Towards A Synthesis Of Professional And Community Police Models

Directory of Open Access Journals (Sweden)

Suve Priit

2015-06-01

Full Text Available In this article we analyse professional police and community policing in view of professionalism, strategy and structures. We aim to find ways for synthesizing these models that are usually seen as incompatible. Unlike many earlier studies of police organizations or strategies, we view strategies in the organization at the corporate, functional and operational levels, and argue that by combining them with functional and divisional principles of structuring, it is possible to place professional strategy at the core of policing, while using the community policing strategy mainly as a component part of the strategy in the framework of divisional organization. This way it is possible to avoid the risk of alienating police from the community and to ensure the successful implementation of corporate strategy through providing professional police units that perform the narrow functions, with quick and adequate information from the community.

Gastric emptying

Gastric emptying (GE) of nutriments is a major function of the stomach. GE disorders are observed after gastric surgery and with various diseases, either of a strictly gastroenterologic kind or interesting other specialities (especially diabetes mellitus). Scintigraphy, which has allowed a better knowledge of GE physiological and pathological mechanisms, has now become the reference method for studying the emptying of solids and liquids. In a near future, it could well have two major applications: a diagnostic approach of functional digestive disorders and an assessment of the various effects of pharmacological drugs with digestive affinity [fr

Police Training in El Salvador: Challenges and Opportunities in Promoting the Community Police Model

Directory of Open Access Journals (Sweden)

Luisa Carolina Arévalo Herrera

2014-05-01

Full Text Available The Peace Accords emphasized creating a new police force that would be diametrically opposite to previous security forces. This change would have to be expressed symbolically, and from the onset it would have to underscore the fact that the main weapon of the police would be intelligence. From its foundation to June 2011, a total of 30,344 people have graduated from the Academy. Currently, in the process of training new police with greater quality, and modernizing the entire police force, it faces the difficult challenge of adopting the Community Police philosophy to empower this model for action, promoting a new relationship between community and law enforcement, and between managers and operational personnel in the agency. Nevertheless,police training is not enough if there are no significantchanges in the organizational climate and culture within the law enforcement agency.DOI: http://dx.doi.org/10.5377/rpsp.v1i1.1390

The Media Representations of Police Image

Directory of Open Access Journals (Sweden)

Wayne W. L. Chan

2015-09-01

Full Text Available The Hong Kong Police Force has undergone one of its biggest challenges in the Occupy Movement that emerged in the last year. Despite the sheer complexity of the police roles, we know little about its representations in the media coverage, and even less about the extent to which the imagery impacts of police acting as peacekeepers would have been made upon the images of police acting as crime fighters. Against this background, this empirical research aims to investigate the police image and its relation to the police’s specifically categorized duties in Hong Kong. The content analysis of local newspaper accounts is used as the research method. It is found that there would be generally negative media representations of police in the order-maintenance work whereas the police images in the crime-fighting duties could still remain positive. The reasons for these findings and their implications for the conceptions of the police role are discussed.

2017-10-01

In this analysis we quantify the wallclock time used by short empty pilot jobs on a number of WLCG compute resources. Pilot factory logs and site batch logs are used to provide independent accounts of the usage. Results show a wide variation of wallclock time used by short jobs depending on the site and queue, and changing with time. For a reference dataset of all jobs in August 2016, the fraction of wallclock time used by empty jobs per studied site ranged from 0.1% to 0.8%. Aside from the wall time used by empty pilots, we also looked at how many pilots were empty as a fraction of all pilots sent. Binning the August dataset into days, empty fractions between 2% and 90% were observed. The higher fractions correlate well with periods of few actual payloads being sent to the site.

2017-06-01

Full Text Available Background: Occupational stress and associated physical and mental health related issues are not addressed in Indian police personnel with adequate importance. Methods: Cross-sectional survey was conducted among police personnel (both male and female in Calicut urban police district, Kerala state, India. Police personnel from all designations (ranks, except from the all India services (Indian Police Service were included in the study. Data were collected using a specifically designed datasheet covering socio-demographic profile, physical and mental health related details which was prepared by researchers. Occupational stress was measured using Operational Police Stress Questionnaire (PSQ-OP and Organisational Police Stress Questionnaire (PSQ-ORG. Result: The study found that both operational and organisational stress was significant among the police officers. Organisational stress was experienced in moderate level by 68% and in high level by 14%. Operational stress scores were in the moderate range in 67% and in high range in 16.5%. The younger age group (21-35 years and lower level rank police personnel had higher stress. Stress was higher among female police personnel compared to males. While 23% of them had been diagnosed with physical illnesses, a significant four per cent of them with mental illness, and 29% of them reported substance abuse. Conclusion: The results point to the high level of stress among Indian police personnel and the need for urgent interventions from the government to address the occupational stress.

Simultaneous gastric emptying of two solid foods

Weiner, K.; Graham, L.S.; Reedy, T.; Elashoff, J.; Meyer, J.H.

1981-01-01

A variety of radionuclide-labeled, solid foods have been used to measure gastric emptying. Implicit is the idea that the nuclide label identifies the rate of emptying of meal contents. The present studies tested whether different foods empty from the human stomach at different rates. Eight volunteers were fed meals of 200 ml of water + 213 g of beef stew + 52 g of chicken liver, with half the liver as 0.25-mm particles and half as 10-mm chunks, labeled with /sup 99m/Tc and /sup 113m/In, respectively, or the reverse. Another 8 subjects ingested 200 ml of water + 75 g of noodles, labeled with /sup 123/I, + 30 g of liver, labeled with /sup 113/In. Gastric emptying of each radionuclide was determined for 3 h by measuring the decline of counts in the gastric region of interest, using an Ohio Nuclear S410 gamma camera interfaced to a DEC computer. In each case, appropriate corrections were made for nuclear decay, down-scatter from /sup 113m/In, and septal penetration. Seven of 8 subjects emptied 0.25-mm liver particles more quickly than 10-mm chunks of liver, while 1 subject emptied the two sizes of liver at the same rate. The t 1/2 for the 0.25-mm liver was 70 +/- 10 min; and for the 10-mm liver, 117 +/- 19 min (p less than 0.05). Six of 8 subjects emptied noodles much faster than liver, while 2 emptied the two foods at similar rates. The t 1/2 for the noodles was 52 +/- 8 min; and for the liver, 82 +/- 5 min (p less than 0.02). Since different foods in the same meal were found to empty at different rates, we conclude the gastric emptying of every food in a meal is not accurately represented by the emptying of a single, nuclide-labeled food. The different t 1/2s for the emptying of 10-mm liver in the two meals (p less than 0.05) probably reflected the influence of other meal components on gastric motility

2016-06-01

An online survey gathered the experiences and views of 394 police officers (from England and Wales) regarding autism spectrum disorder (ASD). Just 42 % of officers were satisfied with how they had worked with individuals with ASD and reasons for this varied. Although officers acknowledged the need for adjustments, organisational/time constraints were cited as barriers. Whilst 37 % of officers had received training on ASD, a need for training tailored to policing roles (e.g., frontline officers, detectives) was identified. Police responses are discussed with respect to the experiences of the ASD community (31 adults with ASD, 49 parents), who were largely dissatisfied with their experience of the police and echoed the need for police training on ASD.

The European Union as a Comprehensive Police Actor

Directory of Open Access Journals (Sweden)

Stephen Anthony Rozée

2011-12-01

Full Text Available The European Union (EU has responded to changing security threats by seeking to increase cooperation between the law enforcement agencies of the Member States, granting further powers to Europol and other intelligence-sharing institutions, and by undertaking police missions beyond EU borders. The literature relating to EU policing is generally focused on the ‘internal’ and ‘external’ dimensions, or on specific aspects of police activity. This tendency to concentrate on narrow or isolated areas of policing has led to a significant gap regarding the broader analysis of the EU as a comprehensive police actor. Important questions about the nature of EU policing as a whole, as well as the contribution of policing activities to the EU’s security agenda, remain unexplored in the literature. This article aims to define what is meant by ‘comprehensive policing’ and to indentify criteria by which the comprehensiveness of EU-level policing may be measured. In addition to this, an integrated actorness/police comprehensiveness framework will be presented as a tool for assessing the EU as a comprehensive police actor.

There have been a number of reports of gastric emptying in cirrhosis, all with unconfirmed results. Moreover, the mechanism for delayed emptying in cirrhotic patients in unclear. We evaluated gastric emptying in patients with chronic hepatitis and cirrhosis by means of gastric emptying scintigraphy. The subjects were 18 normal controls and 75 patients with chronic viral hepatitis (50 patients had chronic hepatitis and 25 patients had cirrhosis). Tc-99m diethyltriamine pentaacetic acid labeled solid meals were used to evaluate gastric emptying; the half-time (T 1/2) of which was calculated. Digestive symptom scores were determined at the time of gastric emptying tests. Fourteen (28%) of 50 patients with chronic hepatitis and 16 (64%) of 25 patients with cirrhosis had delayed gastric emptying. T 1/2 in patients with cirrhosis was significantly higher than that in normal controls and patients with chronic hepatitis (p=0.0001 and 0.0003, respectively). The difference between T 1/2 in patients with chronic hepatitis and that in normal controls was not significant. On regression analysis, two indices, the serum albumin level and platelet count, were found to be significantly related to delayed gastric emptying. Gastric emptying was more delayed in cirrhotic patients than in those with chronic hepatitis and normal controls. Delayed gastric emptying may be related to liver function and portal hypertension.

Symptoms of patients with autoimmune gastritis are not specific, and some patients may present symptoms suggestive of delayed gastric emptying. This study aims to investigate whether any delay in gastric emptying of solid food exists in patients with autoimmune gastritis and, if so, to identify the factors that might affect delayed gastric emptying. A total of 165 patients (106 women) diagnosed as having autoimmune gastritis were analyzed by means of a gastric emptying test. All patients underwent a standardized scintigraphic gastric emptying study. Patients with delayed gastric emptying and normal gastric emptying tests were then compared by means of factors that might affect gastric emptying. Also 65 patients with functional dyspepsia who had a gastric emptying study constituted the control group. The median gastric emptying T ½ time was 127.43 min (min-max 50-953) for patients with AIG and 81 min (min-max 21-121.6) for functional dyspepsia patients (p gastritis, gastric emptying is generally delayed. Autoimmune gastritis is an important etiology to explain the finding of delayed gastric emptying on a radionuclide test. This new finding is likely to be relevant to clinicians when evaluating and initiating appropriate medical treatment for patients with autoimmune gastritis manifesting upper gastrointestinal symptoms.

Recent advances in gastric emptying scintigraphy

International Nuclear Information System (INIS)

Urbain, J.L.C.; Mayeur, S.M.

1996-01-01

Gastric emptying scintigraphy was introduced more than 25 years ago by Grittith and still remains the gold standard to assess gastric emptying. Test meals, radiopharmaceuticals and acquisition procedures have been refined and optimized over the years and the test procedure is now pretty well standardized. However, in its most common use, gastric emptying scintigraphy provides little information on gastric physiology. Over the last decade, modelling of the liquid and solid emptying curves have brought some insight in the complex gastric physiology. Compartmental analysis of the stomach has also provided information on the pathophysiological mechanisms of delayed gastric emptying. Over the past 5 years, the most dramatic development in gastric emptying scintigraphy has been the introduction of Digital Antral Scintigraphy (DAS). Digital Antral scintigraphy basically consists in dynamically imaging of the stomach and the use of a refined Fourier transform processing method. This new procedure allows for the visualization of antral contractions and, alike manometry, permits quantitative characterization on the frequency and amplitude of these contractions. Overall, this new procedure provides a unique, non invasive tool to characterize gastric motility, to define the pathophysiologic mechanisms of gastric motor disorders and to evaluate the effect of new gastro-kinetic compounds.

Empty seeds are not always bad: simultaneous effect of seed emptiness and masting on animal seed predation.

Directory of Open Access Journals (Sweden)

Ramón Perea

Full Text Available Seed masting and production of empty seeds have often been considered independently as different strategies to reduce seed predation by animals. Here, we integrate both phenomena within the whole assemblage of seed predators (both pre and post-dispersal and in two contrasting microsites (open vs. sheltered to improve our understanding of the factors controlling seed predation in a wind-dispersed tree (Ulmus laevis. In years with larger crop sizes more avian seed predators were attracted with an increase in the proportion of full seeds predated on the ground. However, for abundant crops, the presence of empty seeds decreased the proportion of full seeds predated. Empty seeds remained for a very long period in the tree, making location of full seeds more difficult for pre-dispersal predators and expanding the overall seed drop period at a very low cost (in dry biomass and allocation of C, N and P. Parthenocarpy (non-fertilized seeds was the main cause of seed emptiness whereas seed abortion was produced in low quantity. These aborted seeds fell prematurely and, thus, could not work as deceptive seeds. A proportion of 50% empty seeds significantly reduced ground seed predation by 26%. However, a high rate of parthenocarpy (beyond 50% empty seeds did not significantly reduce seed predation in comparison to 50% empty seeds. We also found a high variability and unpredictability in the production of empty seeds, both at tree and population level, making predator deception more effective. Open areas were especially important to facilitate seed survival since rodents (the main post-dispersal predators consumed seeds mostly under shrub cover. In elm trees parthenocarpy is a common event that might work as an adaptive strategy to reduce seed predation. Masting per se did not apparently reduce the overall proportion of seeds predated in this wind-dispersed tree, but kept great numbers of seeds unconsumed.

Full Text Available The task of this study was to investigate the level of satisfaction of various categories of crime victims with various aspects of police work and behavior. The aim of this research was to examine whether the police treat all victims of crime equally responsibly, or whether there is a significant difference in the satisfaction of various categories of crime victims with various aspects of police work and behavior. On an occasional sample of 150 examinees, we analyzed the level of satisfaction of crime victims in relation to the expectations of the police regarding the reported criminal offenses and then the level of satisfaction towards different aspects of work and conduct of the police, such as reporting crime to the police, environmental conditions of interview and human compassion/empathy of police officers. The results indicate a significant difference in the satisfaction of specified aspects of police work among different categories of victims. Most dissatisfaction was expressed by members of the LGBT community and convicted persons when they appear in the role of victims. The research makes recommendations for improving the quality of the work and behavior of the police towards victims of crime.

Gastric emptying of a semiliquid test meal with 5 MBq /sup 99m/Tc-sulfur colloid as a marker was measured in 97 chronic dyspeptic patients and 16 healthy subjects. A comparison of half emptying time between both showed that chronic dyspeptic patients empty semiliquid meal at a significantly (p < 0.005) slower rate (at 70 +- 33 min) than healthy controls (at 52 x 20 min). The studies indicate that gastric stasis in chronic dyspepsia is not caused by inflammatory changes in gastric or duodenal mucosa nor by different gastric acid secretion. The presence of stasis cannot be predicted sufficiently by anamnestic complaints or endoscopic findings. (author)

Gastroparesis is defined as a delay in gastric emptying in the absence of mechanical obstruction, associated with symptoms such as nausea and / or vomiting, feeling of postprandial gastric fullness, early satiety or epigastric pain for more than 3 months. The gold standard in the diagnosis of delayed gastric emptying scintigraphy is gastric emptying and radiopharmaceutical has been used more 99m Tc-sulfur colloid not available in the country. In order to evaluate the usefulness of colloidal tin in the scintigraphic gastric emptying study, a descriptive study was conducted in 64 patients over 18 years using as radiopharmaceutical 99m Tc-Sn colloid. 31% of patients had symptoms. The emptying time was normal in 50 cases and the association of gastroparesis symptoms was observed in 20 (15 diabetic and 5 non-diabetic), 9 patients had a delayed emptying, but reported no symptoms. Gastroparesis was more frequent in women than in men (35% versus 21%). 21% of patients had a moderate delayed gastric emptying. Conclusions: The results obtained with 99m Tc-Sn colloid are comparable to those reported by other authors using 99m Tc-SC in the scintigraphic assessment of gastric emptying. (author)

Do calories or osmolality determine gastric emptying

International Nuclear Information System (INIS)

Shafer, R.B.; Levine, A.S.; Marlette, J.M.; Morley, J.E.

1984-01-01

Recent animal studies suggest that gastric emptying is dependent on the caloric and osmotic content of the ingested food. These studies have involved intubation with infusion of liquid meals into the stomach. Scintigraphic methods, which are non-invasive and do not alter normal physiology, are now available for precise quantitation of gastric emptying. To study the role of calories and osmolality on gastric emptying, the authors employed a standardized /sup 99m/Tc-scrambled egg meal washed with 50 cc tap water in 10 normal human volunteers. A variety of simple and complex sugars, non-absorbable complex carbohydrate (polycose), medium chain fatty acid (MCFA) and gluten were dissolved in water and ingested with the test meal. Each subject acted as his own control. Coefficient of variation in control tests in each subject 12 weeks apart was 9.9%. Results showed that incremental glucose (25-66 gm) produced a linear increase in gastric emptying (T/2 control 50 +- 3, 25 gm 60 +- 3, 50 gm 79 +- 3 and 66 gm 102 +- 3 minutes). 25 gm fructose (T/2 59 +- 3 minutes) and 25 gm polycose (T/2 59 +- 3 minutes) had similar effects to glucose. 25 gm sucrose and 25 gm gluten did not significantly differ from controls. MCFA had an effect similar to 50 gm glucose - suggesting that calories are important in gastric emptying. However, 25 gm xylose markedly prolonged gastric emptying to 80 +- 5 minutes. The rank order for osmolality for substances tested MCFA = gluten < polycose < polycose < fructose < sucrose = glucose < xylose defined no relationship to gastric emptying. The authors' results suggest that neither calories nor osmolality alone determine gastric emptying. A specific food does not necessarily have the same effect on gastric emptying in different individuals

Gastric emptying is usually measured in animals and humans by dilution/sampling or external scintigraphy. These methods are either time consuming or require expensive equipment. The capacity of a miniature gamma counter positioned in the stomach to measure emptying of liquid and solid meals was evaluated. In eight conscious pigs fitted with gastric and duodenal cannulae, gastric emptying of saline (500 mL), dextrose (20%, 500 mL), porridge (300 g) and scrambled eggs (300 g), all labelled with 3.5 MBq 99mTC, was evaluated. When positioned in the antrum the probe was unable to quantify gastric emptying. In contrast, measurements of the fractional emptying of saline over 4-min periods by the probe positioned in the corpus and quantification of radioactivity in the duodenal effluent correlated closely (r = 0.88, P < 0.05). Gastric emptying (50% emptying time) of saline and both solid meals measured by the probe was not significantly different from quantification of the duodenal effluent volume. No difference was observed also for the dextrose meal but only while gastric acid secretion was suppressed by omeprazole. We conclude that an intragastric gamma counter permits measurement of gastric emptying of homogeneous meals provided meal stimulation of gastric secretion was not extensive. This was possible probably by monitoring emptying from the proximal stomach.

Scintigraphic measurement of gastric emptying time has been reported to be influenced by the variation in depth of radionuclide within the stomach. This study was designed to clarify whether a part of the variability in gastric emptying could be ascribed to a relationship between anterior image, the total anteroposterior image and the tissue attenuation correction(geometric mean). A dual-head scintillation camera(ADAC, USA) was used to investigate effect of such changes. We were performed 16 normal subject gastric emptying studies with 99 mTC labelled scramble egg, milk and solid meal(610 Kcal, 300 g). The results are as follows; On anterior image, T 1/2 emptying time was delayed by 5 min, 6.5%(range : 3 ∼ 18 min, 5∼31.4%) compared with the geometric mean. But there was no different gastric emptying time between the total anteroposterior image and geometric mean. Therefore, if will be useful to use the method of geometric mean or the total anteroposterior image to evaluate the gastric emptying time accurately

To review internationally recognized models of police interactions with people experiencing mental health crises that are sometimes complex and associated with adverse experience for the person in crisis, their family and emergency service personnel. To develop, implement and review a partnership model trial between mental health and emergency services that offers alternative response pathways with improved outcomes in care. Three unique models of police and mental health partnership in the USA were reviewed and used to develop the PACER (Police Ambulance Crisis Emergency Response) model. A three month trial of the model was implemented and evaluated. Significant improvements in response times, the interactions with and the outcomes for people in crisis were some of the benefits shown when compared with usual services. The pilot showed that a partnership involving mental health and police services in Melbourne, Australia could be replicated based on international models. Initial data supported improvements compared with usual care. Further data collection regarding usual care and this new model is required to confirm observed benefits. © The Royal Australian and New Zealand College of Psychiatrists 2015.

Fisher, R.S.; Malmud, L.S.; Bandini, P.; Rock, E.

1982-05-01

The purposes of this study were to use a noninvasive scintigraphic technique to measure gastric emptying of liquids and solids simultaneously, to study the interactions between emptying of the liquid and solid components of meals in normal subjects, and to employ dual isotope gastric scintigraphy to evaluate gastric emptying of liquids and solids in patients with clinical evidence of gastric outlet obstruction. The solid component of the test meal consisted of chicken liver, labeled in vivo with /sup 99m/Tc sulfur colloid, and the liquid component was water mixed with /sup 111/In DTPA. The rates of emptying were quantitated using a gamma camera on line to a digital computer. Twenty normal subjects were studied using this combined solid-liquid meal. Ten of them also ingested a liquid meal alone and ten a solid meal alone. Liquid emptied from the stomach significantly more rapidly than did solids. The emptying curve for liquids was exponential compared to a linear emptying curve for solids. The gastric emptying rate of the liquid component was slowed significantly by simultaneous ingestion of solids, but the emptying rate of solids was not affected by liquids. Several patients with clinical gastric outlet obstruction were evaluated. Both combined and selective abnormalities for gastric emptying of liquids and solids were demonstrated.

Abnormalities of esophageal and gastric emptying in progressive systemic sclerosis

International Nuclear Information System (INIS)

Maddern, G.J.; Horowitz, M.; Jamieson, G.G.; Chatterton, B.E.; Collins, P.J.; Roberts-Thomson, P.

1984-01-01

Gastric and esophageal emptying were assessed using scintigraphic techniques in 12 patients with progressive systemic sclerosis and 22 normal volunteers. Esophageal emptying was significantly delayed in the patient group, with 7 of the 12 patients beyond the normal range. Gastric emptying was slower in patients than in controls, with 9 patients being outside the normal range for solid emptying and 7 patients outside the normal range for liquid emptying. Findings from gastric and esophageal emptying tests generally correlated well with symptoms of dysphagia and gastroesophageal reflux. However, 2 patients with normal emptying studies had symptomatic heartburn, and 2 patients with delay of both solid and liquid gastric emptying gave no history of gastroesophageal reflux. Delayed gastric emptying may be an important factor in the development of upper gastrointestinal symptoms in patients with progressive systemic sclerosis

Food Policing in Early Modern Danish Towns

Directory of Open Access Journals (Sweden)

Jørgen Mührmann-Lund

2016-08-01

Full Text Available This article explores the efforts of early modern authorities to provide food security in three different Danish towns in order to understand the goals and methods of early modern food policing. As in other European countries, urban authorities were expected as part of the regulation called ‘the police’ to control the guilds and fix the prices on bread, meat, beer and other life necessities in order to avoid scarcity among the urban poor. In 1682–83 the Danish king established a police force in Copenhagen and the other market towns. The goal of the metropolitan police was to increase the population of the capital and thus increase the military-fiscal power of the absolutist state, by providing food security and even a comfortable life. In practice, the vigilant policing of bakers, butchers and brewers proved difficult. The positive economic effect of food policing was doubted early on and was reduced as a means to avoid food riots at the end the 18th century. In a major provincial market town like Aalborg, the food trade was policed in a similar manner by the town council and the police, but especially the intermediate trade proved difficult to stop. In a tiny, agrarian market town like Sæby, food policing was more a question of feeding the poor with the town’s own products.

In this prospective, clinical study, four groups, each consisting of 12 patients were established to determine how gastric emptying is influenced in cholelithiasis with accompanied flatulent dyspepsia and the relationship of symptoms and gastric emptying after cholecystectomy: group 1--healthy people; group 2--patients with dyspeptic cholelithiasis; group 3--patients with no dyspepsia after cholecystectomy; group 4--patients with dyspepsia after cholecystectomy. Groups are compared according to solid phase gastric emptying scintigraphies performed with Tc 99m sulphur colloid bound with scrambled eggs. Gastric emptying delayed in groups 2 (P 0.005). These results demonstrate that dyspepsia, in cholelithiasis and persisting after cholecystectomy, has a close relation with delay in gastric emptying.

The police state myth

International Nuclear Information System (INIS)

Spinrad, B.I.

1985-01-01

This chapter attempts to refute the assertion made by antinuclear groups that the use of nuclear energy will lead to a suppression of civil liberties in the US. The ''police state'' argument is based on the belief that the management of nuclear materials would necessitate the investigation of the stability and loyalties of their managers, and that in an instance of the theft of nuclear weapons material, police countermeasures might have to include violations of due process with regard to entry and search. It is pointed out that the screening of a person for a responsible position does not violate due process, and the fact that nuclear materials are radioactive and can be easility detected at some distance indicates that close police searches would not be necessary in the case of theft

Erythromycin, a macrolide antibiotic, has recently been shown to have a motilin like effect on gastrointestinal muscle strips. In this study, we have evaluated the effect of erythromycin on patients with delayed gastric emptying and healthy subjects using the dual radionuclide technique. Twelve patients with gastroparesis diabeticorum and ten healthy age- and sex-matched controls were studied. Gastric emptying of solids and liquids was determined using 99mTc-SC scrambled egg and 111In-DTPA in water. Following a baseline study and on a separate day, each patient and control received a 15-min i.v. perfusion of erythromycin starting at meal ingestion. Eleven out of the 12 patients were restudied after a 3-wk oral administration. In patients and controls, i.v. erythromycin dramatically accelerated gastric emptying of both solids and liquids which were emptied at the same rate. After chronic oral administration, solid and liquid emptying remained significantly accelerated. Erythromycin appears to be a very powerful gastrokinetic drug. Derived compounds with the gastrokinetic effect and without the antibiotic activity could be useful in dyspeptic patients with delayed gastric emptying

Scintigraphic evaluation of gastric emptying and motility

International Nuclear Information System (INIS)

Linke, R.

2003-01-01

The stomach consists of two functionally distinct parts. The fundus and upper corpus mainly serve as a reservoir and exert primarily a tonic activity, which presses ingesta towards the antrum and duodenum. The phasic contractility of the lower corpus and antrum cause mechanical breakdown and mixing of the food particels. A complex regulation of these mechanisms provides a regular gastric emptying. Various disorders such as diabetes mellitus, mixed connective tissue diseases, gastritis, tumors, dyspeptic disorders but also drugs and gastric surgery may influence or impair gastric function and may cause typical symptoms such as upper abdominal discomfort, bloating, nausea and vomiting. However, the interpretation of gastrointestinal symptoms often is difficult. Radionuclide studies of gastric emptying and motility are the most physiologic tools available for studying gastric motor function. Gastric scintigraphy is non-invasive, uses physiologic meal and is quantitative. Emptying curves generated from the gastric ROI offer information whether a disorder is accompanied by a regular, fast or slow gastric emptying. Data on gastric contractions (amplitude and frequency) provide additional information to results obtained by conventional emptying studies. Depending on the underlying disorder, gastric emptying and peristalsis showed both corresponding and discrepant findings. Therefore, both parameters should be routinely assessed to further improve characterisation of gastric dysfunction by scintigraphy. (orig.) [de

Effect of solids, caloric content on dual-phase gastric emptying

The dual-phase gastric emptying technique is routinely employed to determine the differential emptying of solids and liquids in a wide spectrum of gastrointestinal diseases. Composition, acidity, volume, caloric density, physical form and viscosity of the test means have been shown to be important determinants for the quantitative evaluation of gastric emptying. In this study, the authors have evaluated the effect of increasing the caloric content of the solid portion of a physiologic test mean on both solid and liquid emptying kinetics in health male volunteers. They observed that increasing solid caloric content delayed emptying of both solids and liquids. For the solid phase, the delay was accounted for by a longer lag phase and decrease in emptying rate; for liquids a longer emptying rate was also obtained. They conclude that modification of the caloric content of the solid portion of a meal not only affects the emptying of the solid phase but also alters the emptying of the liquid component of the meal.

Analysis of empty ATLAS pilot jobs

CERN Document Server

Love, Peter; The ATLAS collaboration

2016-01-01

The pilot model used by the ATLAS production system has been in use for many years. The model has proven to be a success with many advantages over push models. However one of the negative side-effects of using a pilot model is the presence of 'empty pilots' running on sites which consume a small amount of walltime and not running a useful payload job. The impact on a site can be significant with previous studies showing a total 0.5% walltime usage with no benefit to either the site or to ATLAS. Another impact is the number of empty pilots being processed by a site's Compute Element and batch system which can be 5% of the total number of pilots being handled. In this paper we review the latest statistics using both ATLAS and site data and highlight edge cases where the number of empty pilots dominate. We also study the effect of tuning the pilot factories to reduce the number of empty pilots.

To evaluate the gastric emptying time of pharmaceutical dosage forms in a clinical setting, a relatively simple dual-radionuclide technique was developed. Placebo tablets of six different combinations of shape and size were labeled with indium-111 DTPA and enteric coated. Six volunteers participated in a single-blind and crossover study. Tablets were given in the morning of a fasting stomach with 6 oz of water containing /sup 99m/Tc pertechnetate and continuously observed with a gamma camera. A scintigraph was obtained each minute. The results suggested that the size, shape, or volume of the tablet used in this study had no significant effect in the rate of gastric emptying. The tablets emptied erratically and unpredictably, depending upon their time of arrival in the stomach in relation to the occurrence of interdigestive myoelectric contractions. The method described is a relatively simple and accurate technique to allow one to follow the gastric emptying of tablets

Pouch emptying of solid foods after gastroplasty for morbid obesity

1985-01-01

To obtain information on possible determinants of weight loss after horizontal gastroplasty, pouch emptying was prospectively investigated in 27 morbidly obese patients. A scintigraphic method was used. Examinations were carried out every 6 months until 2 years after surgery. Pouch emptying...... was described by means of delay, time until half emptying, mean transit time, and emptying rate. The measures all showed a significant (p less than 0.05) acceleration of pouch emptying during the first 6 months after gastroplasty. Thereafter pouch emptying was unaltered. No significant association could...

A standard, dual-isotope meal (Tc-99m-egg sandwich and In-111 DTPA in water) was administered to 14 normal volunteers and 37 patients, who had not undergone gastric surgery, to determine if the emptying characteristics of the liquid phase alone could accurately predict delayed solid emptying. Delayed gastric emptying was defined clinically as a solid half-emptying time more than two standard deviations greater than the mean for normal volunteers. Linear regression analysis was performed on the natural logarithm of liquid fractional retention at each time interval to yield a slope and y-intercept for each subject. There was no significant difference (0.6 less than P less than 0.8) between volunteers and patients with normal solid emptying for the liquid slope. In patients who exhibited delayed gastric emptying for solids, the liquid slopes were significantly different from the normal values (P less than .001). There was a high correlation of liquid slope to solid half-emptying time in all patients and volunteers (r = -0.80, P less than .001). Comparison of the liquid slope measurement to solid half-emptying time criteria revealed a sensitivity of 96%, a specificity of 100%, and a predictive value of 100% for the slope test. These results suggest that delayed gastric emptying can be accurately detected with a liquid-solid meal using only a single-liquid label.

PREDICTING RELEVANT EMPTY SPOTS IN SOCIAL INTERACTION

Institute of Scientific and Technical Information of China (English)

Yoshiharu MAENO; Yukio OHSAWA

2008-01-01

An empty spot refers to an empty hard-to-fill space which can be found in the records of the social interaction, and is the clue to the persons in the underlying social network who do not appear in the records. This contribution addresses a problem to predict relevant empty spots in social interaction. Homogeneous and inhomogeneous networks are studied as a model underlying the social interaction. A heuristic predictor function method is presented as a new method to address the problem. Simulation experiment is demonstrated over a homogeneous network. A test data set in the form of market baskets is generated from the simulated communication. Precision to predict the empty spots is calculated to demonstrate the performance of the presented method.

1993-07-01

The purpose of this study was to determine whether obese patients have different rates of solid and liquid gastric emptying compared to healthy controls. Twenty-four obese patients (7 males, 17 females) were investigated prior to dietary restriction. The patients had a weight excess above ideal weight ranging from 25% to 216% (mean weight 118.1 +/- 6.5 kg). The control group consisted of 8 healthy subjects (4 males, 4 females), within 10% of the ideal weight. The solid phase of the test meal consisted of 40 g bread, 30 g ham, 10 g margarine, and two scrambled eggs labeled with 99mTc. For the liquid phase, 200 ml orange juice was labeled with 201Tl. Three-minute counts of both tracers were taken for 106 min using a large field-of-view gamma camera. In obese patients, a significantly shortened lag phase for the emptying of solids was observed (27.0 +/- 3.3 versus 38.4 +/- 4.1 min; P < 0.05). Half-emptying time (105.9 +/- 6.7 versus 100.7 +/- 5.7 min), emptying rate (0.60 +/- 0.04 versus 0.71 +/- 0.07%/min), and total emptying of solids (49.4 +/- 3.6 versus 50.5 +/- 5.0%) were not different from controls. Obese subjects had a trend to slowed liquid emptying (half-time 82.7 +/- 4.8 versus 69.9 +/- 6.9 min; emptying rate 0.59 +/- 0.03 versus 0.65 +/- 0.03%/min; total emptying 59.8 +/- 2.9 versus 66.0 +/- 3.3%), but this was not statistically significant. There was no correlation between weight or body surface area and rate of solid or liquid gastric emptying.(ABSTRACT TRUNCATED AT 250 WORDS)

Behavioral Variables Associated with Obesity in Police Officers

CAN, S. Hakan; HENDY, Helen M.

2014-01-01

Past research has documented that non-behavioral variables (such as long work hours, exposure to police stressors) are associated with obesity risk in police officers, but limited research has examined behavioral variables that might be targeted by Employee Assistance Programs for police weight management. The present study compared non-obese and obese officers for behavioral variables found associated with obesity in other adult samples: physical activity (cardiovascular, strength-training, stretching), sleep duration, and consumption of alcohol, fruit and vegetables, and snack foods. Participants included 172 male police officers who completed questionnaires to report height and weight, used to calculate body mass index (BMI = kg/m2) and to divide them into “non-obese” and “obese” groups. They also reported the above behaviors and six non-behavioral variables found associated with obesity risk: age, health problems, family support, police work hours, police stressors, police support. ANCOVAs compared each behavioral variable across obesity status (non-obese, obese), with the six non-behavioral variables used as covariates. Results revealed that cardiovascular and strength-training physical activity were the only behavioral variables that differed significantly between non-obese and obese police officers. The use of self-reported height and weight values may provide Employee Assistance Program with improved cost, time, and officer participation. PMID:24694574

Theories of police legitimacy – its sources and effects

Directory of Open Access Journals (Sweden)

Pavla Homolová

2018-04-01

Full Text Available The review of theories on police legitimacy aims at introducing the subject with a multidisciplinary approach. It quotes criminological, sociological as well as psychological and institutional theories of legitimacy, in order to provide the reader a rich framework, in which the findings of the presented current empirical studies can be evaluated. Police legitimacy is conceived as a social phenomenon, closely related to social norms such as socially constructed police roles and models of policing. The prevailing normative model of police legitimacy in criminology is discussed in greater detail, including critical outlook on procedural fairness as the assumed main source of police empirical legitimacy. Recent findings concerning legal socialization and theories of legitimization myths are high- lighted in order to supplement the micro-level oriented criminological literature on police legitimacy. Possible future pathways of legitimacy research in criminology are discussed.

Building capability throughout a change effort: leading the transformation of a police agency to community policing.

Science.gov (United States)

Ford, J Kevin

2007-06-01

This case describes a change effort to move a police agency to become a community policing organization. The community policing effort was seen as a means to make a transformational change to become a learning organization with the goal of improving the delivery of police services. The case describes the steps taken to meet the new vision of community policing as well as the steps taken to deal with the challenges or realities of trying to make change happen. The lens for this case is the leadership role across the stages of change (exploration, planning, implementation, monitoring and institutionalization) in building capacity within the organization to sustain the change effort. The capacity building focused on incorporating systems thinking into the mindset of the members of the organization, breaking down the command and control mindset by building a new norm around high involvement of committed teams, and developing skill sets to support continuous learning and improvement in order to align organizational systems. A key lesson learned is that effective leaders do not just prepare an organization prior to a change effort. They must have the patience to constantly build the capacity for change among organizational members throughout the various stages of the change effort.

Microspheres of pancreatin should empty from the stomachs of patients with pancreatic insufficiency as fast as food. The present study was undertaken in 26 healthy subjects to identify the size of spheres that would empty from the stomach with food and to determine whether different meals alter this size. Spheres of predefined sizes were labeled with /sup 113m/In or /sup 99m/Tc. Using a gamma-camera, we studied the concurrent gastric emptying of spheres labeled with /sup 113m/In and of chicken liver labeled with /sup 99m/Tc in 100-g, 154-kcal or 420-g, 919-kcal meals, or the concurrent emptying of 1-mm vs. larger spheres. One-millimeter spheres emptied consistently (p less than 0.01, paired t-test) faster than 2.4- or 3.2-mm spheres when ingested together with either the 420- or 100-g meals. Thus, in the 1-3-mm range of diameters, sphere size was a more important determinant of sphere emptying than meal size. Statistical analyses indicated that spheres 1.4 +/- 0.3 mm in diameter with a density of 1 empty at the same rate as /sup 99m/Tc-liver. Our data indicate some commercially marketed microspheres of pancreatin will empty too slowly to be effective in digestion of food

A study of the dynamics of gastric emptying

International Nuclear Information System (INIS)

Shibatsuji, Hiroshi

1985-01-01

Factors influencing gastric emptying were studied by measuring gastric emptying time (GET) with RI experimentally and clinically. The restlts are as follows: 1. The parasympathetic blockers suppressed gastric emptying but the parasympathetic stimulater did not accelerate it. 2. Posture of the subject in measurement influenced gastric emptying and GET was reduced in order of prone, sitting and supine positions. 3. In cases of gastric and duodenal ulcer, there were differences of GET between pre-operation and post-operation depending on the methods of operation. 4. The GET was measured to investigate the gastric emptying of liquid and solid food by double RI tracer method, using 99m Tc-DTPA and 111 In-DTPA which were measured separately. The GET of liquid food was faster than that of solid food and was influenced by the stickiness of coexistent solid food. On the other hand, the GET of solid food tended to be faster with increasing stickiness. (author)

Mandatory medical examinations (MMEs) of workers should be based on the health and safety requirements that are needed for effectively performing the relevant work. For police personnel in the Netherlands, no job-specific MME exists that takes the specific tasks and duties into account. To provide the Dutch National Police with a knowledge base for job-specific MMEs for police personnel that will lead to equitable decisions from an occupational health perspective about who can perform police duties. We used a stepwise mixed-methods approach in which we included interviews with employees and experts and a review of the national and international literature. We determined the job demands for the various police jobs, determined which were regarded as specific job demands and formulated the matching health requirements as specific as possible for each occupation. A total of 21 specific job demands were considered relevant in different police jobs. These included biomechanical, physiological, physical, emotional, psychological/cognitive and sensory job demands. We formulated both police-generic and job-specific health requirements based on the specific job demands. Two examples are presented: bike patrol and criminal investigation. Our study substantiated the need for job-specific MMEs for police personnel. We found specific job demands that differed substantially for various police jobs. The corresponding health requirements were partly police-generic, and partly job-specific. © The Author 2017. Published by Oxford University Press on behalf of the Society of Occupational Medicine.

This study examines relationships between the frequency and intensity of police work stressors and cardiac vagal control, estimated using the high frequency component of heart rate variability (HRV). This is a cross-sectional study of 360 officers from the Buffalo New York Police Department. Police stress was measured using the Spielberger police stress survey, which includes exposure indices created as the product of the self-evaluation of how stressful certain events were and the self-reported frequency with which they occurred. Vagal control was estimated using the high frequency component of resting HRV calculated in units of milliseconds squared and reported in natural log scale. Associations between police work stressors and vagal control were examined using linear regression for significance testing and analysis of covariance for descriptive purposes, stratified by gender, and adjusted for age and race/ethnicity. There were no significant associations between police work stressor exposure indices and vagal control among men. Among women, the inverse associations between the lack of support stressor exposure and vagal control were statistically significant in adjusted models for indices of exposure over the past year (lowest stressor quartile: M = 5.57, 95% CI 5.07 to 6.08, and highest stressor quartile: M = 5.02, 95% CI 4.54 to 5.51, test of association from continuous linear regression of vagal control on lack of support stressor β = -0.273, P = .04). This study supports an inverse association between lack of organizational support and vagal control among female but not male police officers. © 2017 Wiley Periodicals, Inc.

K-9 Police Dog Bite

Directory of Open Access Journals (Sweden)

Vy Han

2017-01-01

Full Text Available History of present illness: A 30-year-old male who was brought into the emergency department (ED by police officers after being bitten in the right lower extremity by a police German Shepard after attempting to flee authorities on foot. The patient stated that the dog immediately bit down on his right calf and proceeded to violently shake its head side to side without releasing its grip until police manually pulled the dog off of him. Upon arrival to the ED, he was tachycardic in the 120’s, complaining of severe, throbbing, sharp pain in the right lower extremity, and was neurovascular intact on exam. Significant findings: The photograph is of the anterior compartment of the right lower leg demonstrating multiple deep lacerations with exposed and torn muscle. X-ray showed no foreign body. Discussion: Police dog bites should be treated more cautiously than typical dog bites because these highly-trained dogs are generally larger breeds which are taught to subdue suspects with a bite-and-hold technique rather than bite and release. This can lead to extensive crush injuries, fractures, large caliber lacerations with associated muscle tissue injury and/or severe neurovascular compromise.1 Hence, police dog bites often require provocative diagnostic testing, specialist consultation for possible operative repair, and aggressive irrigation and ultimately admission for intravenous antibiotics.1 This patient’s wound was aggressively irrigated and evaluated by plastic surgery in the ED. He was ultimately admitted for intravenous antibiotics, pain control, wound care, and healing by secondary intention.

Gradients of fear: How perception influences fear generalization.

Science.gov (United States)

Struyf, Dieter; Zaman, Jonas; Hermans, Dirk; Vervliet, Bram

2017-06-01

The current experiment investigated whether overgeneralization of fear could be due to an inability to perceptually discriminate the initial fear-evoking stimulus from similar stimuli, as fear learning-induced perceptual impairments have been reported but their influence on generalization gradients remain to be elucidated. Three hundred and sixty-eight healthy volunteers participated in a differential fear conditioning paradigm with circles of different sizes as conditioned stimuli (CS), of which one was paired to an aversive IAPS picture. During generalization, each subject was presented with one of 10 different sized circles including the CSs, and were asked to categorize the stimulus as either a CS or as novel after fear responses were recorded. Linear mixed models were used to investigate differences in fear generalization gradients depending on the participant's perception of the test stimulus. We found that the incorrect perception of a novel stimulus as the initial fear-evoking stimulus strongly boosted fear responses. The current findings demonstrate that a significant number of novel stimuli used to assess generalization are incorrectly identified as the initial fear-evoking stimulus, providing a perceptual account for the observed overgeneralization in panic and anxiety disorders. Accordingly, enhancing perceptual processing may be a promising treatment for targeting excessive fear generalization. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

Variability of gastric emptying measurements in man employing standardized radiolabeled meals

Brophy, C.M.; Moore, J.G.; Christian, P.E.; Egger, M.J.; Taylor, A.T.

1986-01-01

Radiolabeled liquid and solid portions of standardized 300-g meals were administered on four different study days to eight healthy subjects in an attempt to define the range of inter- and intrasubject variability in gastric emptying. Meal half emptying times, analysis of variance, and intraclass correlations were computed and compared within and between subjects. The mean solid half emptying time was 58 +/- 17 min (range 29-92), while the mean liquid half emptying time was 24 +/- 8 min (range 12-37). A nested random effects analysis of variance showed moderate intrasubject variability for solid emptying and high intrasubject variability for liquid emptying. The variability of solid and liquid emptying was comparable and relatively large when compared with other reports in the literature. The isotopic method for measuring gastric emptying is a valuable tool for investigating problems in gastric pathophysiology, particularly when differences between groups of subjects are sought. However, meal emptying time is a variable phenomenon in healthy subjects with significant inter- and intraindividual day-to-day differences. These day-to-day variations in gastric emptying must be considered in interpreting individual study results

Review article: gastric emptying in functional gastrointestinal disorders.

LENUS (Irish Health Repository)

Quigley, E M M

2012-02-03

Although delayed gastric emptying has been described in several functional gastrointestinal disorders, and appears to be especially common in functional dyspepsia, the relationship of this finding to symptoms and basic pathophysiology is difficult to define. The delineation of the interactions between delayed gastric emptying, on the one hand, and symptom pathogenesis, on the other, has been hampered by several factors. These include the limitations of the methodology itself, the extent of overlap between the various functional disorders and the sensitivity of gastric emptying to factors external to the stomach, be they elsewhere within the gastrointestinal tract, in the central nervous system or in the environment. In many instances, delayed gastric emptying is an epiphenomenon, reflecting the overlap between inadequately defined functional syndromes, shared pathophysiology or the activation of physiological interactions between the various organs of the gut. In others, it may imply a truly diffuse motor disorder. The disappointments attendant on attempts to alleviate symptoms through approaches designed to accelerate gastric emptying should therefore not come as a surprise. Pending the definition of the true significance of delayed gastric emptying in all functional gastrointestinal disorders, caution should be exerted in the interpretation of this finding in a patient with functional symptoms.

Shifting repertoires: Understanding cultural plurality in policing

OpenAIRE

Hendriks, Frank; van Hulst, Merlijn

2016-01-01

The police is one of the most prominent organizations in the frontline of public administration. In order to deal with high external expectations, the organization has been said to develop and nurture multiple police cultures. Applying Grid Group Cultural Theory, or GGCT, we address the following questions: what sets of values, beliefs and practices has the police organization developed to deal with high expectations stemming from their publics? How do cultural tensions play out in real-life ...

Women in International Policing: Replacing an “Old Boys Club”?

Directory of Open Access Journals (Sweden)

Saskia Hufnagel

2018-03-01

Full Text Available Globalisation has increased the importance of international police cooperation. While cross-border law enforcement can be traced back as far as the Nineteenth Century, police cooperation today—such as Joint Investigation Teams, International Liaison Officers, and Interpol—only came about in the Twentieth Century. It was developed to counter transnational organised crime, such as drug crime and immigration crime, as well as terrorism. But, another aspect of international policing is that of peacekeeping; that is, the deployment of national police to countries during or after conflict to maintain law and order where the local police do not have sufficient capacities. This paper examines how women have been elevated in this police cooperation role, particularly Interpol and international peacekeeping. The discussion focuses on whether there are indications that internationally related tasks and agencies provide a more accepting environment for female police officers as opposed to a national police force setting.

Scintigraphic demonstration of single- or two-phase gastric emptying in diabetics

International Nuclear Information System (INIS)

Eikman, E.A.; Leichter, S.; Waldholtz, B.; Tenorio, L.; Brady, P.

1989-01-01

This paper discusses how a modified scintigraphic test of gastric emptying revealed two types of abnormal gastric emptying in diabetic patients. After ingestion of 100 mL of cooked egg whites labeled with 0.5 mCi of Tc-99m sulfur colloid, the geometric mean stomach radioactivity was recorded serially for 90 minutes. Linear regression computed for the log of radioactivity versus time facilitated recognition of changes in gastric emptying. In 16 of 25 consecutive diabetic patients with postprandial symptoms, initial slow emptying (half-life,>100 minutes) was observed. Single-phase emptying was shown in seven of these patients. In nine patients, the slow-emptying phase lasted up to 50 minutes, followed by a distinct second phase of normal or rapid emptying (half-life, <40 minutes). The existence of different gastric emptying implies differing mechanisms of delay and may be important in treatment

Stomach emptiness in fishes: Sources of variation and study design implications

Science.gov (United States)

Vinson, M.R.; Angradi, T.R.

2011-01-01

This study summarizes fish stomach content data from 369,000 fish from 402 species in 1,096 collections and reports on the percentage of individuals with empty stomachs. The mean percentage of individuals with empty stomachs among all species, locations, habitats, seasons, regions, and collection methods was 26.4%. Mean percentage of individuals with empty stomachs varied significantly among fish collection gear types, taxonomic orders, trophic groups, feeding behaviors, and habitats, and with species length at maturity. Most of the variation in percentage of individuals with empty stomachs was explained by species length at maturity, fish collection gear type, and two autecological factors: trophic group (piscivore percentage of individuals with empty stomachs > non-piscivore percentage of individuals with empty stomachs) and feeding habitat (water column feeder percentage of individuals with empty stomachs > benthic feeder percentage of individuals with empty stomachs). After accounting for variation with fish length, the percentage of individuals with empty stomachs did not vary with the stomach removal collection method (dissection vs. gastric lavage), feeding time (diurnal or nocturnal), or time of collection (day or night). The percentage of individuals with empty stomachs was similar between fresh and saltwater fish, but differed within finer habitat classifications and appeared to follow a general prey availability or productivity gradient: percentage of individuals with empty stomachs of open ocean collections > estuary collections, lentic > lotic, and pelagic > littoral. Gear type (active or passive) was the most influential factor affecting the occurrence of empty stomachs that can be readily controlled by researchers.

Are fear memories erasable? –reconsolidation of learned fear with fear relevant and fear-irrelevant stimuli

OpenAIRE

Armita eGolkar; Martin eBellander; Andreas eOlsson; Arne eÖhman

2012-01-01

Recent advances in the field of fear learning have demonstrated that a single reminder exposure prior to extinction training can prevent the return of extinguished fear by disrupting the process of reconsolidation. These findings have however proven hard to replicate in humans. Given the significant implications of preventing the return of fear, the purpose of the present study was to further study the prerequisites for the putative effects of disrupting reconsolidation.

Simulation of empty container logistic management at depot

Science.gov (United States)

Sze, San-Nah; Sek, Siaw-Ying Doreen; Chiew, Kang-Leng; Tiong, Wei-King

2017-07-01

This study focuses on the empty container management problem in a deficit regional area. Deficit area is the area having more export activities than the import activities, which always have a shortage of empty container. This environment has challenged the trading companies in the decision making in distributing the empty containers. A simulation model that fit to the environment is developed. Besides, a simple heuristic algorithm with some hard and soft constraints consideration are proposed to plan the logistic of empty container supply. Then, the feasible route with the minimum cost will be determined by applying the proposed heuristic algorithm. The heuristic algorithm can be divided into three main phases which are data sorting, data assigning and time window updating.

Gastric emptying studies in the morbidly obese before and after gastroplasty

Energy Technology Data Exchange (ETDEWEB)

Christian, P.E.; Datz, F.L.; Moore, J.G.

1986-11-01

Dual isotope gastric emptying studies were performed on 16 morbidly obese patients before and after gastroplasty to determine the effect of this surgery on the rate of emptying. The solid and liquid phases of gastric emptying were compared with a normal control group. In the 900-g and 50-g meals there was a significant difference in the mean half emptying time between solid and liquid phases of emptying (p less than 0.05). Pre-operatively, the 900-g meal half emptying times of both solids and liquids and the 50-g liquid phase meal did not differ significantly between obese patients and the control group. However, in the solid phase of the 50-g meal obese patients differed significantly from a control group (p = 0.007). Three months after gastroplasty, gastric emptying of 50-g meals from the total stomach was not significantly changed from the pre-operative 50-g meal values in ten of 12 patients (p less than 0.05) and no change in total stomach emptying times were seen at 12 mo compared to the 3-mo study (p less than 0.05). Emptying of the pouch alone for both solids and liquids was significantly faster than the pre-operative and postoperative total stomach studies. Gastric emptying in the obese is normal with large meals, but is delayed in small meals. In most patients, gastroplasty does not result in slower emptying of meals.

Postpyloric regulation of gastric emptying in rhesus monkeys.

Science.gov (United States)

McHugh, P R; Moran, T H; Wirth, J B

1982-09-01

Saline (0.9% NaCl) empties rapidly and exponentially from the stomach of the rhesus monkey, but glucose solutions empty at a calorie-constant rate of 0.4 kcal/min. By means of indwelling intragastric and intraduodenal cannulae we can demonstrate an inhibition on the delivery of saline from the stomach provoked by glucose placed beyond the pylorus. The inhibition varies directly with the glucose calories in the intestine and averages 2.5 min/kcal. That these two results (0.4 kcal/min and 2.5 min/kcal) are reciprocals suggests a feedback inhibition on the gastric emptying of nutrients arising from beyond the pylorus and adequate to explain the rate of glucose delivery to the intestine. A control theory description of gastric emptying that includes such feedback regulation can be derived from these data to explain the different gastric emptying patterns of nutrients and nonnutrient solutions. These patterns give this visceral system a precision in its management of nutrients that can provide information crucial to preabsorptive satiety.

Running from fear: Exercise modulation of fear extinction.

Science.gov (United States)

Tanner, Margaret K; Hake, Holly S; Bouchet, Courtney A; Greenwood, Benjamin N

2018-03-31

Extinction-based exposure therapy is the most common behavioral therapy for anxiety and trauma-related disorders, but fear tends to resurface even after successful extinction. Identification of novel strategies to enhance fear extinction and reduce fear relapse is of paramount importance to mental health. Exercise can enhance cognitive function, but it is not yet well understood whether exercise can be an effective augmentation strategy for fear extinction. In the current review, we present the current state of knowledge on the effects of exercise on fear extinction. Effects of exercise duration, explanations for conflicting results, and potential mechanisms, focusing on a hypothesized role for dopamine, are all discussed. We also provide new data suggesting that the timing in which acute exercise occurs relative to fear extinction, is a crucial variable in determining whether exercise can enhance fear extinction. Clinical implications and ideas to guide future research endeavors in this area are provided. Copyright © 2018 Elsevier Inc. All rights reserved.

Variability of gastric emptying time using standardized radiolabeled meals

International Nuclear Information System (INIS)

Christian, P.E.; Brophy, C.M.; Egger, M.J.; Taylor, A.; Moore, J.G.

1984-01-01

To define the range of inter- and intra-subject variability on gastric emptying measurements, eight healthy male subjects (ages 19-40) received meals on four separate occasions. The meal consisted of 150 g of beef stew labeled with Tc-99m SC labeled liver (600 μCi) and 150 g of orange juice containing In-111 DTPA (100 μCi) as the solid- and liquid-phase markers respectively. Images of the solid and liquid phases were obtained at 20 min intervals immediately after meal ingestion. The stomach region was selected from digital images and data were corrected for radionuclide interference, radioactive decay and the geometric mean of anterior and posterior counts. More absolute variability was seen with the solid than the liquid marker emptying for the group. The mean solid half-emptying time was 58 +- 17 min (range 29-92) while the mean liquid half-emptying time was 24 +- 8 min (range 12-37). A nested random effects analysis of variance showed moderate intra-subject variability for solid half-emptying times (rho = 0.4594), and high intra-subject variability was implied by a low correlation (rho = 0.2084) for liquid half-emptying. The average inter-subject differences were 58.3% of the total variance for solids (rho = 0.0017). For liquids, the inter-subject variability was 69.1% of the total variance, but was only suggestive of statistical significance (rho = 0.0666). The normal half emptying time for gastric emptying of liquids and solids is a variable phenomenon in healthy subjects and has great inter- and intra-individual day-to-day differences

1999-01-01

Full text: As part of a larger study looking at gastric emptying times in cystic fibrosis, we assessed the normal range of gastric emptying in a control group of children. Thirteen children (8 girls, 5 boys) aged 4-15 years (mean 10) were studied. Excluded were children with a history of relevant gastrointestinal medical or surgical disease, egg allergy or medication affecting gastric emptying. Imaging was performed at 08.00 h after an overnight fast. The test meal was consumed in under 15 min and comprised one 50 g egg, 80 g commercial pancake mix, 10 ml of polyunsaturated oil, 40 ml of water and 30 g of jam. The meal was labelled with 99 Tc m -macroaggregates of albumin. Water (150 ml) was also consumed with the test meal. One minute images of 128 x 128 were acquired over the anterior and posterior projections every 5 min for 30 min, then every 15 min until 90 min with a final image at 120 min. Subjects remained supine for the first 60 min, after which they were allowed to walk around. A time-activity curve was generated using the geometric mean of anterior and posterior activity. The half emptying time ranged from 55 to 107 min (mean 79, ± 2 standard deviations 43-115). Lag time (time for 5% to leave stomach) ranged from 2 to 26 min (mean 10). The percent emptied at 60 min ranged from 47 to 73% (mean 63%). There was no correlation of half emptying time with age. The normal reference range for a test meal of pancakes has been established for 13 normal children

Full text: Our purpose was to evaluate the gallbladder (GB) emptying in pts with chronic pancreatitis and to determine whether or not the use of pancreatic extract has an impact in improving that function. The GB emptying was evaluated in 11 patients (pts) with mild to moderate chronic pancreatitis, and in 10 normal volunteers. Pts and controls who presented any kind of condition that could interfere with the gastric or gallbladder emptying were excluded. The GB ejection fraction was calculated at 30, 45, and 60 minutes after a standardized fatty meal ingestion. In the pts group, this evaluation was obtained in two different periods of time, without and with the addition of pancreatic extract. The gastric emptying was previously determined in all patients and controls with Technetium-99m-sulfur colloid mixed in the same fatty meal used for the hepatobiliary scans. The results disclosed that the GB ejection fraction at 60 minutes was significantly lower in patients compared to controls ( 0,05). The gastric emptying was similar between the two groups (p>0,05). In conclusion, mild to moderate chronic pancreatitis is associated with GB function impairment. Our results suggest that the delay in GB emptying does not depend exclusively on the alteration in the intestinal phase of the GB stimulation, but may be a result of multiple other factors

Health in police officers: Role of risk factor clusters and police divisions.

Science.gov (United States)

Habersaat, Stephanie A; Geiger, Ashley M; Abdellaoui, Sid; Wolf, Jutta M

Law enforcement is a stressful occupation associated with significant health problems. To date, most studies have focused on one specific factor or one domain of risk factors (e.g., organizational, personal). However, it is more likely that specific combinations of risk factors are differentially health relevant and further, depend on the area of police work. A self-selected group of officers from the criminal, community, and emergency division (N = 84) of a Swiss state police department answered questionnaires assessing personal and organizational risk factors as well as mental and physical health indicators. In general, few differences were observed across divisions in terms of risk factors or health indicators. Cluster analysis of all risk factors established a high-risk and a low-risk cluster with significant links to all mental health outcomes. Risk cluster-by-division interactions revealed that, in the high-risk cluster, Emergency officers reported fewer physical symptoms, while community officers reported more posttraumatic stress symptoms. Criminal officers in the high-risk cluster tended to perceived more stress. Finally, perceived stress did not mediate the relationship between risk clusters and posttraumatic stress symptoms. In summary, our results support the notion that police officers are a heterogeneous population in terms of processes linking risk factors and health indicators. This heterogeneity thereby appeared to be more dependent on personal factors and individuals' perception of their own work conditions than division-specific work environments. Our findings further suggest that stress-reduction interventions that do not target job-relevant sources of stress may only show limited effectiveness in reducing health risks associated with police work.

The paper studied the problem of empty wagons adjustment of Chinese heavy-haul railway. Firstly, based on the existing study of the empty wagons adjustment of heavy-haul railway in the world, Chinese heavy-haul railway was analyzed, especially the mode of transportation organization and characteristics of empty wagons adjustment. Secondly, the optimization model was set up to solve the empty wagons adjustment of heavy-haul railway and the model took the minimum idling period as the function goal. Finally, through application and solution of one case, validity and practicability of model and algorithm had been proved. So, the model could offer decision support to transport enterprises on adjusting empty wagons.

Examining Police Strategic Resource Allocation in a Time of Austerity

Directory of Open Access Journals (Sweden)

Garth den Heyer

2014-03-01

Full Text Available The increasing importance of proactive policing has highlighted the need to ensure that the police utilise their resources both efficiently and effectively. Traditionally, police agencies have allocated resources in response to their operational demands or requirements, with the majority of resources being distributed in response to political demands and public calls for service. In recent years there has been a greater emphasis by police to deliver services proactively, and to direct resources to specific geographic areas of high crime or to specific crimes, and to apply intelligence led targeted policing initiatives. The changing operating environment to a public service ethos of accountability and ‘do more with less’ means that historical methods of allocating police officers may not meet an agency's strategic goals. This paper examines if an economic approach to allocating police strategic resources is an appropriate and equitable method in a time of austerity. This greater emphasis on proactive, rather than reactive policing, which also represents a shift from centralised control, underlines the need to ensure the efficient and effective use of resources.

Despite their limited mental health expertise, police are often first to respond to people experiencing a mental health crisis. Often the person in crisis is then transported to hospital for care, instead of receiving more immediate assessment and treatment in the community. The current study conducted an evaluation of an Australian joint police-mental health mobile response unit that aimed to improve the delivery of a community-based crisis response. Activity data were audited to demonstrate utilization and outcomes for referred people. Police officers and mental health clinicians in the catchment area were also surveyed to measure the unit's perceived impact. During the 6-month pilot, 296 contacts involving the unit occurred. Threatened suicide (33%), welfare concerns (22%) and psychotic episodes (18%) were the most common reasons for referral. The responses comprised direct admission to a psychiatric unit for 11% of contacts, transportation to a hospital emergency department for 32% of contacts, and community management for the remainder (57%). Police officers were highly supportive of the model and reported having observed benefits of the unit for consumers and police and improved collaboration between services. The joint police-mental health clinician unit enabled rapid delivery of a multi-skilled crisis response in the community. © 2015 Australian College of Mental Health Nurses Inc.

When the threat level of foreign stability operations increases, military police units can make an effective contribution, especially when conducted with the Australian Federal Police. It is argued that, if Australian military police can apply police harmonisation techniques and improve their ability to conduct civilian-like policing duties, then their role in future rule-of-law operations are likely to be more effective.

Police Tweets and Public Perceptions of Safety and Police Performance: An Experiment on Framing and Other Tweet Content

Directory of Open Access Journals (Sweden)

Imke Smulders

2017-05-01

Full Text Available The introduction of new media as a means of communication by the police triggers interesting questions about the impact of such new developments, such as the effect on people’s safety perceptions. Since communication is mostly overlooked as a possible determinant of safety perception, this led to a research project into the relationship between Twitter use by community policing officers and citizen’s perceptions of safety. This article reports on a part of this study, an experiment on framing and other linguistic effects of tweets by police officers. To assess the aforementioned relationship, it is important to examine how the precise content of a community policing officer’s tweet is perceived by the public. In an experimental setting the effects of gain versus loss frames, implicit versus explicit advice and style of addressing have been tested, with regard to safety perceptions and several related factors. The results show that gain framed tweets yield significantly more positive responses concerning opinion about police performance, perceived risk of burglary or assault, safety perception and marginally for perceived crime level in the neighbourhood. Including an explicitly or implicitly formulated piece of advice in the tweets doesn’t make a difference in any of the queried variables and style of addressing has only small effects: formal address leads to slightly more positive opinions about police performance than impersonal address.  The results show that formulation aspects – specifically framing – are worth taking into account in safety communications and that this type of research is beneficial for studying effects of social media.

Brown, J; Cooper, C; Kirkcaldy, B

1996-02-01

From a survey of over 500 senior UK police officers completing the occupational stress inventory, it was observed that those serving in England and Wales exhibited the highest job stress related to structure and climate, co-worker relationships and their managerial role. There were no inter-regional differences on the individual difference variables, Type A behaviour, locus of control, or on physical health measures. Superintendents in Scotland used coping methods least frequently including domestic/home support, time management and social support, the latter strategy being most used by Northern Ireland officers. Findings relating job stress to job satisfaction were inconsistent with other police populations. Results are discussed in the context of organizational reform in the police service.

Remembrance of Things Past: Somali Roads to Police Development

Directory of Open Access Journals (Sweden)

Alice Hills

2014-03-01

Full Text Available Police reform is thought to require a police force to break with its past. This is notably so in the aftermath of conflict or regime change. In practice, however, most police forces are selectively reconstituted, and their development is influenced as much by legacy issues as by international standards filtered through local norms. This article uses the experience of Somalia’s three regional police forces to reconsider the relationship between past and present projects to build police authority and capacity, and what this says about institutional memory in the absence of documentation. In Somalia, as in other clan or tribal-based societies, police development is influenced by a blend of security levels, political imperatives, pragmatism, international resources and memories of past practices, with group experience playing a more significant role than institutional memory. The only identifiable general principle is the need for political settlements and tactical flexibility – that is, for stability.

Police Response to Children Present at Domestic Violence Incidents.

Swerin, Danielle D; Bostaph, Lisa Growette; King, Laura L; Gillespie, Lane Kirkland

2018-01-01

Police response to domestic violence (DV) has continued to change and expand over the past several decades. Although DV was originally considered a private matter, it now represents one of the most common calls for service received by police agencies. While police response to DV incidents has improved substantially, intervention when children are present remains an undeveloped area of research and practice. The present study examined 345 police reports from an agency in the Northwestern United States to explore police response to DV incidents when children are present. Regression analyses indicated that child presence was a statistically significant predictor of victim-directed intervention, victim-directed follow-up, and arrest although in differing directions. While child presence increased the odds of victim-directed intervention and victim-directed follow-up, it decreased the odds of arrest. Findings further indicated that the frequency of police interaction with children present at DV incidents was minimal. Based on these findings, recommendations for policy and practice are discussed.

Police Legitimacy and Compliance With the Law Among Chinese Youth.

Science.gov (United States)

Liu, Siyu; Liu, Jianhong

2017-11-01

The process-based model of policing garnered considerable support in the discourse on police legitimacy. However, findings are largely based on Western contexts, and little attention has been paid to the model advanced by Tyler that police legitimacy helps promote compliance. Using a high school sample ( N = 711) from China, we follow Tankebe's operationalization and examine the role of legitimacy in youth support for the police and whether legitimacy helps predict compliance with the law. Findings indicate that procedural justice and shared values are strong predictors of youth support to the police, and this support positively predicts compliance with the law. Distributive fairness exerts an independent effect on compliance while having been questioned by the police is negatively related to compliance.

Full Text Available Using interview data on LGBT young people’s policing experiences, I argue policing and security works as a program of government (Dean 1999; Foucault 1991; Rose 1999 that constrains the visibilities of diverse sexuality and gender in public spaces. While young people narrated police actions as discriminatory, the interactions were complex and multi-faceted with police and security working to subtly constrain the public visibilities of ‘queerness’. Same sex affection, for instance, was visibly yet unverifiably (Mason 2002 regulated by police as a method of governing the boundaries of proper gender and sexuality in public. The paper concludes by noting how the visibility of police interactions with LGBT young people demonstrates to the public that public spaces are, and should remain, heterosexual spaces.

The New Community Policing: Developing a Partnership-Based Theoretical Foundation

Directory of Open Access Journals (Sweden)

Adam J McKee

2016-10-01

Full Text Available This paper presents a Partnership Model of Community Policing based on Partnership concepts developed by Riane Eisler and undergirded by Cultural Transformation Theory as a guiding principle (1987, 2010, 2013. This model is more reflective of the daily lived experiences of community police officers. It is culturally relevant and based on the whole of the police officer’s relationship with the community within the context in which the interactions occur. This "New Community Policing" is an extension of Riane Eisler’s Cultural Transformation Theory and is an attempt to answer her call for a movement towards a partnership model of social organization. Ultimately, "8 Pillars of the New Community Policing" are developed to aid in defining and implementing community policing.

Several information-processing models highlight the independent roles of controlled and automatic processes in explaining fearful behavior. Therefore, we investigated whether direct measures of controlled processes and indirect measures of automatic processes predict unique variance components of children's spider fear-related behavior. Seventy-seven children between 8 and 13 years performed an Affective Priming Task (APT) measuring associative bias, a pictorial version of the Emotional Stroop Task (EST) measuring attentional bias, filled out the Spider Anxiety and Disgust Screening for Children (SADS-C) in order to assess self-perceived fear, and took part in a Behavioral Assessment Test (BAT) to measure avoidance of spiders. The SADS-C, EST, and APT did not correlate with each other. Spider fear-related behavior was best explained by SADS-C, APT, and EST together; they explained 51% of the variance in BAT behavior. No children with clinical levels of spider phobia were tested. The direct and the different indirect measures did no correlate with each other. These results indicate that both direct and indirect measures are useful for predicting unique variance components of fear-related behavior in children. The lack of relations between direct and indirect measures may explain why some earlier studies did not find stronger color-naming interference or stronger fear associations in children with high levels of self-reported fear. It also suggests that children with high levels of spider-fearful behavior have different fear-related associations and display higher interference by spider stimuli than children with non-fearful behavior.

Behavioral Variables Associated with Obesity in Police Officers

OpenAIRE

CAN, S. Hakan; HENDY, Helen M.

2014-01-01

Past research has documented that non-behavioral variables (such as long work hours, exposure to police stressors) are associated with obesity risk in police officers, but limited research has examined behavioral variables that might be targeted by Employee Assistance Programs for police weight management. The present study compared non-obese and obese officers for behavioral variables found associated with obesity in other adult samples: physical activity (cardiovascular, strength-training, ...

Gastric emptying of solids: When should we sample

Gastric emptying of solids has been studied for 20 normal volunteers using Tc-99m-sulfur-colloid labeled chicken liver or eggs. Residual gastric activity measured in 15 min intervals for 2 1/2 hrs was used to calculate gastric emptying. The procedure was proposed and is used to examine patients for suspected abnormal emptying. This approach however ties up one gamma camera and one technologist for a period of 2 1/2 - 3 hrs. Furthermore to classify any value more the 1SD below the mean as abnormal includes 16% of normals as abnormally low (false positives). In order to find the pattern of abnormalities and the best time to study patients we analyzed the results of 54 studies performed in patients with a variety of clinical problems. Gastric emptying was measured in 30 min intervals for 2 1/2 hrs after a standard meal of 2 scrambled eggs labeled with 1 mCi of Tc-99m-sulfur-colloid, 2 slices of bread and 300 ml of juice. To choose the point important to observe the authors studied the distribution of values at each time-point to determine when there is the greatest variability from the reported normal. When there is delayed emptying the 2 1/2 hr observation is the best discriminator and when there is accelerated emptying the 60 min observation is the best discriminator. In the group of patients the 150 min observation had no correlation with the age of the patients. It is possible that sampling at a later time could be more discriminatory. The authors propose sampling at 0, 60, and 150 min time as the most informative and cost effective approach to study the solid gastric emptying. The 2SD rather than 1SD below and above the mean should be used as the level to separate normal from abnormal results

Full Text Available Objectives: The aim of the present study was to determine the physical activity levels of active duty police officers and police academy cadets in different life domains and intensities. These parameters were treated as potential quantifiers that could be used when assessing individuals preparing for work as future police officers. Material and Methods: The study recruited 153 active police officers and 176 cadets attending a police academy and administered a diagnostic survey, the long-form version of the International Physical Activity Questionnaire, while in the statistical analysis the Student's t-test for independent groups was applied. Results: It was determined that police officers present high physical activity levels within the work domain, which are developed from initial training at a police academy and then throughout their police career. Conclusions: Such data are important in the light of the role police officers play in public safety as well as the prominence of physical activity within a particular profession and how it can be targeted and tailored to their needs.

Development and validation of the Attitudes Towards Police Legitimacy Scale.

Reynolds, Joshua J; Estrada-Reynolds, Victoria; Nunez, Narina

2018-04-01

Although there is a substantial body of work examining attitudes towards the police, no measure has been developed to consistently capture citizens' beliefs regarding police legitimacy. Given that police conduct has garnered a great deal of attention, particularly in the last few years, the current research sought to develop a scale measuring perceptions of police legitimacy. Across multiple studies, items were created and the scale's factor structure explored (Study 1 and Study 2), the factor structure was confirmed (Study 3a), and the predictive validity of the scale was tested (Studies 3b-3d). Results provided evidence for a reliable and valid 34-item scale with a single-factor solution that predicted multiple outcomes, including justification of a police shooting (Study 3b) and resource allocation to a police charity (Study 3c), as well as correlations with self-reported criminal activity, right-wing authoritarianism, and social dominance orientation (Study 3d). We hope this scale will be useful in the study of police legitimacy, expanding the current literature, and improving police-community relations.

The police are the frontline workers in crisis situations involving patients with severe mental illness and act as a primary referral source for psychiatric emergency services (PES) in the community. The aims of this study were to investigate the distribution and characteristics of police referral among psychiatric patients in Taiwan. The study cohort consisted of patients who visited the PES of Taipei City Psychiatric Center from January 2009 to December 2010. The associations between the factors of demographics, clinical characteristics, and psychiatric service utilization and police referral were evaluated. Among the 7656 psychiatric emergency visits, 3029 (39.6%) were referred by the police. These patients referred by police were more likely to be male and aged between 30 to 49 years. Clinical factors related to police referrals including a higher triage assessment level, chief problems included violence, disturbance, substance use, less anxiety, and a diagnosis of unspecified psychosis. The triage assessment level and chief problems assessed by nurses were major predictors. These patients tended to be referred from the catchment area and during the nighttime shift, were discharged during the daytime shift, and stayed longer in the PES. Disposition arrangements such as discharge against medical advice and involuntary admission were also associated with police referrals. Patients referred by the police to the PES were those with more severe psychiatric problems and illnesses assessed by psychiatric nurses and psychiatrists. They tended to have more complex service utilization at the PES. © 2015 Wiley Publishing Asia Pty Ltd.

Inhibitory effects of xylitol on gastric emptying and food intake

Shafer, R.B.; Levine, A.S.; Marlette, J.M.; Morley, J.E.

1985-01-01

The authors have previously shown, using a 99m-Tc scrambled egg meal, that pentose sugars (i.e. xylose and arabinose) markedly prolong gastric emptying. Others have reported that slowing of gastric emptying may decrease appetite and thus decrease food intake. In the present study, the authors utilized the effects of xylitol (an FDA-approved pentose sugar) on gastric emptying to study the correlation between gastric emptying and food intake. Initially, gastric emptying was measured in human volunteers utilizing a standardized 99m-Tc-scrambled egg meal washed with 50 cc tap water. Results demonstrated a significant reduction in food intake (892 +- 65 kcal with water vs 654 +- 26 kcal following the ingestion of 25 gm xylitol (p<0.05). We conclude that the effect of pentose sugars in prolonging gastric emptying directly influences food intake and contributes to early satiety. The data suggest a role of xylitol as an essentially non-caloric food additive potentially important in diet control

A Test of Evolutionary Policing Theory with Data from Human Societies

Kümmerli, Rolf

2011-01-01

In social groups where relatedness among interacting individuals is low, cooperation can often only be maintained through mechanisms that repress competition among group members. Repression-of-competition mechanisms, such as policing and punishment, seem to be of particular importance in human societies, where cooperative interactions often occur among unrelated individuals. In line with this view, economic games have shown that the ability to punish defectors enforces cooperation among humans. Here, I examine a real-world example of a repression-of-competition system, the police institutions common to modern human societies. Specifically, I test evolutionary policing theory by comparing data on policing effort, per capita crime rate, and similarity (used as a proxy for genetic relatedness) among citizens across the 26 cantons of Switzerland. This comparison revealed full support for all three predictions of evolutionary policing theory. First, when controlling for policing efforts, crime rate correlated negatively with the similarity among citizens. This is in line with the prediction that high similarity results in higher levels of cooperative self-restraint (i.e. lower crime rates) because it aligns the interests of individuals. Second, policing effort correlated negatively with the similarity among citizens, supporting the prediction that more policing is required to enforce cooperation in low-similarity societies, where individuals' interests diverge most. Third, increased policing efforts were associated with reductions in crime rates, indicating that policing indeed enforces cooperation. These analyses strongly indicate that humans respond to cues of their social environment and adjust cheating and policing behaviour as predicted by evolutionary policing theory. PMID:21909429

In infants with recurrent vomiting, and especially bilious vomiting, the algorithmic approaches is to perform conventional barium upper gastrointestinal radiography to rule out malrotation and midgut volvulus, which are surgical emergencies. However, children with protracted vomiting and failure to thrive are candidates for medical treatment. These children are often evaluated by radionuclide gastric emptying studies to assess gastric emptying. Three patients are presented in whom the radionclude gastric emptying study revealed the presence of a malrotation anomaly which had been undetected by antecedent barium gastrointestinal radiographic studies.

2016-10-01

Full Text Available In the article analysis of general theoretic approaches towards competent and motivated behavior definitions, the model of police officer social competence was proposed along with the ways of its study. Based on development theory conception the initial validation of social competence logical system as a mean of cadets’ social competence evaluation was considered in the article. Additionally, the determination of personality development level as possibility for definition and evaluation of cadets’ social competence based on social behavior theory perspectives was considered. As well the social features of social competence of law­enforcement officers were discussed and the theoretical construction for schematized representation of police cadets’ social competence structure is presented. The model includes: social norms related to police activity; motivation to socially­oriented activity; social intelligence, as integrative characteristic of cognitive and operational processes; emotional steadiness and communication skills. It was stated that the main characteristic of police cadets’ social competence is efficiency of interaction between police and community. The other important factor influencing social competence is professional activity and in our case it is law­enforcement. The social environment of departmental educational institution was explored as a main factor contributing to development of police cadets’ social competence components.

Although social science research has examined police and law enforcement-perpetrated discrimination against Black men using policing statistics and implicit bias studies, there is little quantitative evidence detailing this phenomenon from the perspective of Black men. Consequently, there is a dearth of research detailing how Black men's perspectives on police and law enforcement-related stress predict negative physiological and psychological health outcomes. This study addresses these gaps with the qualitative development and quantitative test of the Police and Law Enforcement (PLE) Scale. In Study 1, we used thematic analysis on transcripts of individual qualitative interviews with 90 Black men to assess key themes and concepts and develop quantitative items. In Study 2, we used 2 focus groups comprised of 5 Black men each (n = 10), intensive cognitive interviewing with a separate sample of Black men (n = 15), and piloting with another sample of Black men (n = 13) to assess the ecological validity of the quantitative items. For Study 3, we analyzed data from a sample of 633 Black men between the ages of 18 and 65 to test the factor structure of the PLE, as we all as its concurrent validity and convergent/discriminant validity. Qualitative analyses and confirmatory factor analyses suggested that a 5-item, 1-factor measure appropriately represented respondents' experiences of police/law enforcement discrimination. As hypothesized, the PLE was positively associated with measures of racial discrimination and depressive symptoms. Preliminary evidence suggests that the PLE is a reliable and valid measure of Black men's experiences of discrimination with police/law enforcement.

2002-01-01

The clinical presentation of patients with vitamin B 12 deficiency varies in a spectrum ranging from haematological disorders to neuropsychiatric diseases. In rare cases, orthostatic hypotension, impotence, constipation and urinary retention have been attributed to autonomic nervous system dysfunction due to vitamin B 12 deficiency. The aim of this study was to evaluate the effect of vitamin B 12 deficiency on autonomic nervous system function by studying gastric emptying times (T 1/2 ). Twenty patients with newly diagnosed vitamin B 12 deficiency and 12 control patients with gastritis and normal vitamin B 12 levels were enrolled in this study. Gastroduodenoscopy, endoscopic biopsy, histopathological evaluation of the biopsy specimens and radionuclide gastric emptying studies were performed. After vitamin B 12 replacement therapy for 3 months, radionuclide gastric emptying studies were repeated. Mean gastric emptying T 1/2 in patients before and after treatment and in controls were 103.83±48.80 min, 90.00±17.29 min and 74.55±8.52 min, respectively. The difference in mean gastric emptying T 1/2 between patients before treatment and controls was statistically significant (P 12 treatment (P 1/2 was somewhat shorter. There were no positive or negative correlations between gastric emptying T 1/2 and the following parameters: haemoglobin, vitamin B 12 level and Helicobacter pylori positivity. In conclusion, gastric emptying T 1/2 was prolonged in patients with vitamin B 12 deficiency and this prolongation was not corrected after vitamin B 12 replacement therapy. Although autonomic nervous system dysfunction due to vitamin B 12 deficiency rarely gives rise to clinical manifestations, latent dysfunction demonstrated by laboratory tests seems to be a frequent phenomenon. The level of vitamin B 12 does not correlate with the degree of autonomic nervous system dysfunction measured by radionuclide gastric emptying studies. (orig.)

Community Policing in Latin America: Lessons from Mexico City

Directory of Open Access Journals (Sweden)

Markus-Michael Müller

2010-04-01

Full Text Available Community policing programmes are widely perceived and promoted as an important solution for the pressing problems of insecurity in contemporary Latin American cities, and for improving citizen-police relationships. By drawing on the results of empirical fieldwork conducted in Mexico City, the article presents a critical analysis of the local community policing effort. The article demonstrates that this policing effort is overly determined by a local context, characterized by clientelism, political factionalism and police corruption, which therefore renders its contribution to a sustainable improvement of local accountability and police legitimacy unlikely. Against this background the article calls for more empirical studies on this topic and a greater sensitivity for the embeddedness of policing programmes within a wider political context.    Resumen: Colaboración ciudadana en América Latina: Lecciones de Ciudad de México  Los programas de colaboración ciudadana son ampliamente percibidos y presentados como una importante solución para los apremiantes problemas de inseguridad en las ciudades latinoamericanas de hoy, y para mejorar las relaciones entre la ciudadanía y la policía. Basándonos en los resultados de trabajo de campo realizado en Ciudad de México, en el presente artículo se ofrece un análisis crítico del programa local de policía comunitaria y se demuestra que está excesivamente determinado por un contexto local caracterizado por el clientelismo, las lealtades políticas y la corrupción policial. Por eso, el aporte del programa a un mejoramiento sustentable de la rendición de cuentas local y de legitimidad policial es improbable. Contra este telón de fondo, en el artículo se demandan más estudios empíricos sobre el tema y una mayor sensibilidad para la integración de los programas de policía comunitaria dentro de un contexto político más amplio.

Police officers are frequently the first responders to individuals in crisis, but generally receive little training for this role. We developed and evaluated training in suicide awareness and prevention for frontline rail police in the UK. To investigate the impact of training on officers' suicide prevention attitudes, confidence, and knowledge. Fifty-three participants completed a brief questionnaire before and after undertaking training. In addition, two focus groups were conducted with 10 officers to explore in greater depth their views and experiences of the training program and the perceived impact on practice. Baseline levels of suicide prevention attitudes, confidence, and knowledge were mixed but mostly positive and improved significantly after training. Such improvements were seemingly maintained over time, but there was insufficient power to test this statistically. Feedback on the course was generally excellent, notwithstanding some criticisms and suggestions for improvement. Training in suicide prevention appears to have been well received and to have had a beneficial impact on officers' attitudes, confidence, and knowledge. Further research is needed to assess its longer-term effects on police attitudes, skills, and interactions with suicidal individuals, and to establish its relative effectiveness in the context of multilevel interventions.

Síndrome de burnout y satisfacción de vida en policías ministeriales mexicanos/Burnout syndrome and life satisfaction in mexican judicial police

2015-08-01

Full Text Available Research on police in Mexico is commonly associated with issues such as distrust or corruption, instead of the detection of psychological needs in the police. Therefore in this work the presence of burnout and life satisfaction in Mexican judicial police were explored. Method: It was carried out a qualitative, descriptive and transversal research. Instrumental case study where four Mexican judicial police answered the Maslach Burnout Inventory and Satisfaction Questionnaire life of Diener. Results: The analysis showed that there are medium-high levels of burnout and some contradictory results in life satisfaction. Conclusions: It is necessary to strengthen the perspective of police psychology to continue the study of burnout in the police sector to detect, prevent and intervene in this problem and improve their living and working conditions.

Enhanced discriminative fear learning of phobia-irrelevant stimuli in spider-fearful individuals

Full Text Available Avoidance is considered as a central hallmark of all anxiety disorders. The acquisition and expression of avoidance which leads to the maintenance and exacerbation of pathological fear is closely linked to Pavlovian and operant conditioning processes. Changes in conditionability might represent a key feature of all anxiety disorders but the exact nature of these alterations might vary across different disorders. To date, no information is available on specific changes in conditionability for disorder-irrelevant stimuli in specific phobia (SP. The first aim of this study was to investigate changes in fear acquisition and extinction in spider-fearful individuals as compared to non-fearful participants by using the de novo fear conditioning paradigm. Secondly, we aimed to determine whether differences in the magnitude of context-dependent fear retrieval exist between spider-fearful and non-fearful individuals. Our findings point to an enhanced fear discrimination in spider-fearful individuals as compared to non-fearful individuals at both the physiological and subjective level. The enhanced fear discrimination in spider-fearful individuals was neither mediated by increased state anxiety, depression, nor stress tension. Spider-fearful individuals displayed no changes in extinction learning and/or fear retrieval. Surprisingly, we found no evidence for context-dependent modulation of fear retrieval in either group. Here we provide first evidence that spider-fearful individuals show an enhanced discriminative fear learning of phobia-irrelevant (de novo stimuli. Our findings provide novel insights into the role of fear acquisition and expression for the development and maintenance of maladaptive responses in the course of SP.

SparseLeap: Efficient Empty Space Skipping for Large-Scale Volume Rendering

KAUST Repository

Hadwiger, Markus; Al-Awami, Ali K.; Beyer, Johanna; Agus, Marco; Pfister, Hanspeter

2017-01-01

Recent advances in data acquisition produce volume data of very high resolution and large size, such as terabyte-sized microscopy volumes. These data often contain many fine and intricate structures, which pose huge challenges for volume rendering, and make it particularly important to efficiently skip empty space. This paper addresses two major challenges: (1) The complexity of large volumes containing fine structures often leads to highly fragmented space subdivisions that make empty regions hard to skip efficiently. (2) The classification of space into empty and non-empty regions changes frequently, because the user or the evaluation of an interactive query activate a different set of objects, which makes it unfeasible to pre-compute a well-adapted space subdivision. We describe the novel SparseLeap method for efficient empty space skipping in very large volumes, even around fine structures. The main performance characteristic of SparseLeap is that it moves the major cost of empty space skipping out of the ray-casting stage. We achieve this via a hybrid strategy that balances the computational load between determining empty ray segments in a rasterization (object-order) stage, and sampling non-empty volume data in the ray-casting (image-order) stage. Before ray-casting, we exploit the fast hardware rasterization of GPUs to create a ray segment list for each pixel, which identifies non-empty regions along the ray. The ray-casting stage then leaps over empty space without hierarchy traversal. Ray segment lists are created by rasterizing a set of fine-grained, view-independent bounding boxes. Frame coherence is exploited by re-using the same bounding boxes unless the set of active objects changes. We show that SparseLeap scales better to large, sparse data than standard octree empty space skipping.

SparseLeap: Efficient Empty Space Skipping for Large-Scale Volume Rendering

KAUST Repository

Hadwiger, Markus

2017-08-28

Recent advances in data acquisition produce volume data of very high resolution and large size, such as terabyte-sized microscopy volumes. These data often contain many fine and intricate structures, which pose huge challenges for volume rendering, and make it particularly important to efficiently skip empty space. This paper addresses two major challenges: (1) The complexity of large volumes containing fine structures often leads to highly fragmented space subdivisions that make empty regions hard to skip efficiently. (2) The classification of space into empty and non-empty regions changes frequently, because the user or the evaluation of an interactive query activate a different set of objects, which makes it unfeasible to pre-compute a well-adapted space subdivision. We describe the novel SparseLeap method for efficient empty space skipping in very large volumes, even around fine structures. The main performance characteristic of SparseLeap is that it moves the major cost of empty space skipping out of the ray-casting stage. We achieve this via a hybrid strategy that balances the computational load between determining empty ray segments in a rasterization (object-order) stage, and sampling non-empty volume data in the ray-casting (image-order) stage. Before ray-casting, we exploit the fast hardware rasterization of GPUs to create a ray segment list for each pixel, which identifies non-empty regions along the ray. The ray-casting stage then leaps over empty space without hierarchy traversal. Ray segment lists are created by rasterizing a set of fine-grained, view-independent bounding boxes.

Oxburgh, Laura; Gabbert, Fiona; Milne, Rebecca; Cherryman, Julie

Despite mentally disordered suspects being over-represented within the criminal justice system, there is a dearth of published literature that examines police officers' perceptions when interviewing this vulnerable group. This is concerning given that police officers are increasingly the first point of contact with these individuals. Using a Grounded Theory approach, this study examined 35 police officers' perceptions and experiences when interviewing mentally disordered suspects. Current safeguards, such as Appropriate Adults, and their experiences of any training they received were also explored. A specially designed questionnaire was developed and distributed across six police forces in England and Wales. Nine conceptual categories emerged from the data that highlighted how police officers' level of experience impacted upon their perceptions when dealing with this cohort. As a consequence, a new model grounded within Schema Theory has emerged termed Police Experience Transitional Model. Implications include the treatment and outcome of mentally disordered suspects being heavily dependent on whom they encounter within the criminal justice system. Copyright © 2016 Elsevier Ltd.

The purpose of the study was to establish a new method of measuring gastric emptying using MR imaging in human. Gastric emptying was measured in 6 healthy male volunteers aged from 28 to 43 years, using MR imaging and RI. The measurements were performed after the oral administration of liquid meal containing glucose, protein and fat. The MR imaging was performed with 0.5T superconducting magnet machine, and consecutive 12 transaxial T1 weighted spin echo images (TR/TE=300/17) of the upper abdomen were recorded every 10 minutes for more than 1 hour. Gastric emptying curves and their T1/2 values obtained by MR imaging and RI method were correlated well in 5 of 6 cases. We concluded that a non-invasive and radiation free method using MR imaging was proved to be a useful tool for measuring gastric emptying. (author).

Empty tracks optimization based on Z-Map model

Liu, Le; Yan, Guangrong; Wang, Zaijun; Zang, Genao

2017-12-01

For parts with many features, there are more empty tracks during machining. If these tracks are not optimized, the machining efficiency will be seriously affected. In this paper, the characteristics of the empty tracks are studied in detail. Combining with the existing optimization algorithm, a new tracks optimization method based on Z-Map model is proposed. In this method, the tool tracks are divided into the unit processing section, and then the Z-Map model simulation technique is used to analyze the order constraint between the unit segments. The empty stroke optimization problem is transformed into the TSP with sequential constraints, and then through the genetic algorithm solves the established TSP problem. This kind of optimization method can not only optimize the simple structural parts, but also optimize the complex structural parts, so as to effectively plan the empty tracks and greatly improve the processing efficiency.

Objectives Although social science research has examined police and law enforcement-perpetrated discrimination against Black men using policing statistics and implicit bias studies, there is little quantitative evidence detailing this phenomenon from the perspective of Black men. Consequently, there is a dearth of research detailing how Black men’s perspectives on police and law enforcement-related stress predict negative physiological and psychological health outcomes. This study addresses these gaps with the qualitative development and quantitative test of the Police and Law Enforcement (PLE) scale. Methods In Study 1, we employed thematic analysis on transcripts of individual qualitative interviews with 90 Black men to assess key themes and concepts and develop quantitative items. In Study 2, we used 2 focus groups comprised of 5 Black men each (n=10), intensive cognitive interviewing with a separate sample of Black men (n=15), and piloting with another sample of Black men (n=13) to assess the ecological validity of the quantitative items. For study 3, we analyzed data from a sample of 633 Black men between the ages of 18 and 65 to test the factor structure of the PLE, as we all as its concurrent validity and convergent/discriminant validity. Results Qualitative analyses and confirmatory factor analyses suggested that a 5-item, 1-factor measure appropriately represented respondents’ experiences of police/law enforcement discrimination. As hypothesized, the PLE was positively associated with measures of racial discrimination and depressive symptoms. Conclusions Preliminary evidence suggests that the PLE is a reliable and valid measure of Black men’s experiences of discrimination with police/law enforcement. PMID:28080104

A multidimensional model of police legitimacy: A cross-cultural assessment.

2016-02-01

This study used survey data from cross-sectional, university-based samples of young adults in different cultural settings (i.e., the United States and Ghana) to accomplish 2 main objectives: (1) to construct a 4-dimensional police legitimacy scale, and (2) to assess the relationship that police legitimacy and feelings of obligation to obey the police have with 2 outcome measures. The fit statistics for the second-order confirmatory factor models indicated that the 4-dimensional police legitimacy model is reasonably consistent with the data in both samples. Results from the linear regression analyses showed that the police legitimacy scale is related to cooperation with the police, and that the observed association is attenuated when the obligation to obey scale is included in the model specification in both the United States and Ghana data. A similar pattern emerged in the U.S. sample when estimating compliance with the law models. However, although police legitimacy was associated with compliance in the Ghana sample, this relationship along with the test statistic for the sense of obligation to obey estimate were both null in the fully saturated equation. The findings provide support for the Bottoms and Tankebe's (2012) argument that legitimacy is multidimensional, comprising police lawfulness, distributive fairness, procedural fairness, and effectiveness. However, the link between police legitimacy and social order appears to be culturally variable. PsycINFO Database Record (c) 2016 APA, all rights reserved.

The majority of police suicide research has focused on larger police departments. Very little research has been done within small departments. The present study compared suicide rates between small and larger police departments. Two Hundred ninty-eight departments were drawn from the U.S. Public Safety Officer Benefits database totaling 119,624 officers. Annual suicide rates were calculated per 100,000 for each of four category (by size of department) and p-values from Chi-square tests were employed to assess differences in rates across categories. The annual suicide rate varied significantly across departments. Smaller police departments had a significantly higher suicide rate than large departments. Possible reasons include lack of availability for mental health assistance, increased workload and danger and community visibility.

External scintigraphy in measuring rate of gastric emptying in beagles

Energy Technology Data Exchange (ETDEWEB)

Theodorakis, M.C.

1980-07-01

The application of external scintigraphy and preparation of a new radiopharmaceutical agent for the investigation of the rate and pattern of gastric emptying in beagles and for the visualization of segments of the intestines have been described. 99mTc-labeled triethylenetetramine-polystyrene resin was mixed in a test meal and was administered to the animal. The gastric emptying rate of the beagle was evaluated by serially recording the gastric radioactivity by means of a scintillation camera. The experimental data indicate that the pattern of gastric emptying of beagles during the first 60 min was monoexponential and the gastric emptying half time was 1.3 h. The usefulness of external scintigraphy as a noninvasive method for determining the gastric emptying rates and for visualizing segments of GI tract in animals has been demonstrated.

1986-01-01

The authors devised a novel method to automate the analysis of nuclear gastric emptying studies. Many previous methods have been used to measure gastric emptying but, are cumbersome and require continuing interference by the operator to use. Two specific problems that occur are related to patient movement between images and changes in the location of the radioactive material within the stomach. Their method can be used with either dual or single phase studies. For dual phase studies the authors use In-111 labeled water and Tc-99MSC (Sulfur Colloid) labeled scrambled eggs. For single phase studies either the liquid or solid phase material is used

Use of force [UOF] by police can result in serious injuries and fatalities. The risk of significant injuries associated with different force modalities is poorly defined. We sought to determine the incidence of police UOF and compare the likelihood of significant injury with different force modalities. A prospective multicenter observational study of all UOF incidents was conducted via mandatory UOF investigations at three mid-sized police agencies over a two year period. Expert physicians reviewed police and medical records to determine injury severity using a priori injury severity stratification criteria. There were 893 UOF incidents, representing a UOF rate of 0.086% of 1,041,737 calls for service (1 in 1167) and 0.78% of 114,064 criminal arrests(1 in 128). Suspects were primarily young (mean age, 31 years; range, 12-86 years) males (89%). The 1,399 force utilizations included unarmed physical force (n = 710, 51%), CEWs (504, 30%), chemical (88, 6.3%), canines (47, 3.4%), impact weapons (9, 0.6%), kinetic impact munitions (8, 0.6%), firearms (6, 0.4%), and other (27, 1.9%). Among 914 suspects, 898 (98%) sustained no or mild injury after police UOF. Significant (moderate or severe) injuries occurred in 16 (1.8%) subjects. Logistic regression analysis shows these are most associated with firearm and canine use. There was one fatality (0.1%) due to gunshots. No significant injuries occurred among 504 CEW uses (0%; 95% confidence interval, 0.0-0.9%). Of the 355 suspects transported to a medical facility, 78 (22%) were hospitalized. The majority of hospitalizations were unrelated to UOF (n = 59, 76%), whereas a minority (n = 19, 24%) were due to injuries related to police UOF. Police UOF is rare. When force is used officers most commonly rely on unarmed physical force and CEWs. Significant injuries are rare. Transport for medical evaluation is a poor surrogate for significant injury due to UOF. Epidemiological, level II.

Worldwide, female sex workers (FSWs) have high rates of HIV. Many factors that escalate their risk lay outside of their control, primarily in the environments in which they practice sex. An understudied yet powerful risk environment is that of police. We qualitatively explored sex workers' interactions with police in their personal and professional lives. Thirty-five FSWs were purposively sampled in Baltimore, MD, in 2012. Women discussed experiences of police verbal harassment, sexual exploitation, extortion, and a lack of police responsiveness to 911 calls in emergencies, largely partner violence. Women's mistrust of police was often developed at an early age and further reinforced by interactions in their personal and professional lives. The study underscores the need for targeting police in reducing sex workers' HIV and other risks. The case for police's role in generating risk is evident, which could be addressed through structural interventions targeting both police practices and policies.

The enlarged sella was encountered ordinarily as intrasellar lesion such as pituitary tumor or secondary increased intracranial pressure without certain mechanism. 1951 Busch discovered from his extensive autopsy cases that defects or incomplete attachment of diaphragm sella brings sella enlargement either slightly or moderately enlarged sella with subarachnoid extension. Toennis et al in 1955 discussed enlarged sella due to via infundibular defects or loosely attached stalk area of diaphragm sella from secondary increased intracranial pressure. Du Boulay and others differentiate the entity of none tumor origin of sella enlargement either from raised intracranial pressure or parasella changes, Hence, 'empty sella' was loosely used terminology. We observed following three representative cases in various empty sella syndrome. Case 1: air extended into the sella by pneumoencephalogram. Case 2: chiasma recess herniated into the sella secondary to dilated third ventricle from right thalamic tumor extension. Case 3: enlarged sella firstly mimic intrasella tumor but found intrasella fluid of cerebro-spinal content of extended subarchnoid space into sella. Above changes readily observed by pneumoencephalogram and other means

Full Text Available Background/Aims: The tetracyclic antidepressant mirtazapine is widely used in cancer patients suffering from anorexia. Although it is known to restore appetite, the exact mechanism remains unknown. The aim of the study was to evaluate if mirtazapine has any effect on gastric emptying in patients suffering from cancer-related anorexia. Materials and Methods: Solid-meal gastric-emptying study using radiolabeled meal was performed in 28 patients suffering from cancer anorexia once at baseline and repeated after 15 days of mirtazapine therapy. Results: At baseline, only 7 (25% patients had normal gastric motility (emptying >70% at 3 h postingestion whereas after treatment, 18 (64.2% patients achieved this limit. Mean % gastric emptying increased from 55.2% ±21.0% to 68.9% ±21.3% (P < 0.001. Mean gastric emptying time (t1/2 before intervention was 314.7 ± 421.0 min which decreased to 116.0 ± 106.7 min after intervention. Results were further analyzed by dividing the patients into two groups based on baseline gastric-emptying study. Group A (normal gastric emptying consisted of seven patients, mean % gastric emptying at baseline and postintervention was 75.0% ±5.25% and 87.57% ±5.94%, respectively (P < 0.018. Group B (delayed gastric emptying consisted of 21 patients, mean % gastric emptying at baseline and postintervention was 48.71% ±18.82% and 62.76% ±16.86%, respectively (P < 0.001. Conclusion: Mirtazapine significantly improves gastric emptying in patients of prostate and breast cancer suffering from cancer-associated anorexia.

It describes the types and prevalence of health disorders encountered in custody and provides an overview of current practice and recent innovations in police custody health care. In contrast to the health of prisoners, the health of police custody detainees has, until recently, received little academic or clinical attention. Studies on health care in police custody identified for this review are limited to a few geographical jurisdictions, including the UK, continental Europe, North America, and Australia. There are significant health concerns among police detainees including acute injury, chronic physical health problems, mental and cognitive disorders, and the risks associated with drug and alcohol intoxication or withdrawal. There is some evidence that deaths in police custody have reduced where attention has been paid to the latter issue. Police personnel continue to experience difficulties identifying detainees with health issues relevant to their safe detention, but research shows that the use of evidence-based screening tools improves detection of such morbidities. Innovations in police custody health care mainly relate to detainees with mental disorders, including improved identification of illness

Pulse Packet Stochastic Model for Gastric Emptying in the Fasted State: A Physiological Approach.

Science.gov (United States)

Talattof, Arjang; Amidon, Gordon L

2018-03-05

Fasted-state gastrointestinal (GI) fluid transit is typically represented as a first-order, deterministic process (averaged and viewed as a continuous approximation). It is, however, most likely a discrete process involving fluid packets interrupted by variable time periods of little to no fluid emptying. In this report we present a physiologically based pulsed-packet gastric fluid emptying model and evaluate it with respect to recent gastrointestinal fluid volume emptying results, published gastric emptying of various dosage forms, and gastric fluid emptying as a function of GI motility. We develop the mathematical model for gastric emptying of discrete volumes emptied during intermittent pulse times of variable lengths, defined as a function of gastric motility utilizing a Poisson point process with motility-dependent intensity. We compare the simulations with observed gastric emptying results. The discrete pulse-packet gastric volumetric emptying model is a more physiologically realistic mathematical model for gastric emptying and it accounts well for the average observed emptying rates and, importantly, encompasses the variability of of observed volume and dosage form emptying rates.

Effect of size and density on canine gastric emptying of nondigestible solids

International Nuclear Information System (INIS)

Meyer, J.H.; Dressman, J.; Fink, A.; Amidon, G.

1985-01-01

Previous studies suggested that the food-containing canine stomach retains large, nondigestible spheres until all food has emptied; but it is not known whether there is a threshold size or a gradation of sizes that will empty along with food. Further, nothing is known of the effects of such parameters as density, shape, and surface energy on the emptying of nondigestible particles of any given size. To answer these questions 6 dogs with chronic duodenal fistulas were studied. Radiolabeled food and spheres were collected from the fistulas to compare the rate of gastric emptying of the spheres with that of the food. After a standard test meal of /sup 99m/Tc-labeled liver, steak, and water, diverted chyme was collected over a stack of sieves in 30-min fractions over 5 postcibal hours. The percent of fed spheres and fed /sup 99m/Tc-labeled liver in each collection was counted, and liquid chyme was returned to the distal duodenum. Spheres with a density of 1 emptied progressively faster as sphere diameters were decreased from 5 to 1 mm; but 0.015-mm spheres emptied at about the same rate as those with diameters of 1 mm. Emptying of the spheres became similar to emptying of the /sup 99m/Tc-labeled liver at about 1.6 mm. Spheres with densities less than 1 or greater than 1 emptied more slowly than spheres of the same size with a density of 1, whereas paper squares emptied the same way as spheres of comparable size and density. Surface energy did not affect emptying. The findings indicated that both sphere size and density affect their emptying in the presence of food

2017-07-01

To examine whether stricter firearm legislation is associated with rates of fatal police shootings. We used a cross-sectional, state-level design to evaluate the effect of state-level firearm legislation on rates of fatal police shootings from January 1, 2015, through October 31, 2016. We measured state-level variation in firearm laws with legislative scorecards from the Brady Center, and for fatal police shootings we used The Counted, an online database maintained by The Guardian. State-level firearm legislation was significantly associated with lower rates of fatal police shootings (incidence rate ratio = 0.961; 95% confidence interval = 0.939, 0.984). When we controlled for sociodemographic factors, states in the top quartile of legislative strength had a 51% lower incidence rate than did states in the lowest quartile. Laws aimed at strengthening background checks, promoting safe storage, and reducing gun trafficking were associated with fewer fatal police shootings. Legislative restrictions on firearms are associated with reductions in fatal police shootings. Public Health Implications. Although further research is necessary to determine causality and potential mechanisms, firearm legislation is a potential policy solution for reducing fatal police shootings in the United States.

The hysterographic (empty bladder) view of the uterus

International Nuclear Information System (INIS)

Carroll, R.; Gombergh, R.

1986-01-01

Technical improvements in transducer design permit a direct coronal view of the uterus (''hysterographic view'') to be obtained with the bladder empty as a valuable complement to the usual US study of the pelvis with the bladder distended. Good visualization of the uterine cavity and wall is possible in 95% of cases. More than 50 cases of endometrial and myometrial pathology (polyps, cancers, submucous fibroids) with abnormalities inapparent on standard US scans have hysterographic and/or pathologic proof confirming the empty-bladder US-based diagnosis. If tubal visualization is not necessary, empty-bladder US may often avoid hysterography. It is also the best way to demonstrate IUD position

The effect of isoperistaltic jejunal interposition upon gastric emptying

Energy Technology Data Exchange (ETDEWEB)

Mackie, C.R.; Hall, A.W.; Clark, J.; Wisbey, M.; Baker, P.R.; Cuschieri, A.

1981-12-01

Ten patients with severe postgastrectomy-postvagotomy symptoms, all of whom had the features of vasomotor dumping, underwent gastric emptying studies, using a 300 milliliter meal of 15 per cent dextrose labeled with 99mTc-sulphur colloid. Studies were repeated two to 11 months following remedial operative treatment, using a 12.5 to 15.0 centimeter isoperistaltic jejunal interposition. Preoperatively, all patients had rapid gastric emptying with a typical biphasic pattern. Following isoperistaltic interposition, the rate of gastric emptying was similar to that found in control patients. Gastric emptying reverted to a more normal pattern but, as in the preoperative studies, was best described by a double exponential function, consisting of slow and fast components. Analysis of these particular functions suggests the manner in which isoperistaltic interposition modified the underlying disorder of gastric motility.

Upper gastrointestinal symptoms may be prominent in anorexia nervosa. This study is an investigation of the gastric emptying of solid and liquid meal components in 16 female patients who met accepted psychiatric diagnostic criteria for anorexia nervosa. The results were compared with those of gastric emptying studies in 10 normal females of ideal body weight, 13 normal persons (12 males), and six patients with weight loss secondary to Crohn's disease with no psychiatric symptoms. A dual-isotope technique using chicken liver intracellularly labeled with technetium-/sup 99m/ (/sup 99m/Tc) bound to sulfur colloid as the solid-phase marker, and indium- 111 ( 111 In) -labeled water as the liquid-phase marker was used. In 13 of the 16 anorexia nervosa patients (80%), gastric emptying of solids was slower than the range in the two groups of normal subjects, and mean gastric emptying was significantly slower than in the weight-loss patients. Liquid emptying (water) in anorexia nervosa was normal and similar to the control groups studied. In 11 of the anorexia nervosa patients with delayed gastric emptying, intramuscular metoclopramide, 10 mg, significantly accelerated the mean gastric emptying from 60 through 120 min after the meal. The authors conclude that these data are consistent with an antral motility disturbance, either primary or secondary; and metoclopramide, a gastric prokinetic agent, accelerates (delayed) gastric emptying

Memory suppression trades prolonged fear and sleep-dependent fear plasticity for the avoidance of current fear

Science.gov (United States)

Kuriyama, Kenichi; Honma, Motoyasu; Yoshiike, Takuya; Kim, Yoshiharu

2013-07-01

Sleep deprivation immediately following an aversive event reduces fear by preventing memory consolidation during homeostatic sleep. This suggests that acute insomnia might act prophylactically against the development of posttraumatic stress disorder (PTSD) even though it is also a possible risk factor for PTSD. We examined total sleep deprivation and memory suppression to evaluate the effects of these interventions on subsequent aversive memory formation and fear conditioning. Active suppression of aversive memory impaired retention of event memory. However, although the remembered fear was more reduced in sleep-deprived than sleep-control subjects, suppressed fear increased, and seemed to abandon the sleep-dependent plasticity of fear. Active memory suppression, which provides a psychological model for Freud's ego defense mechanism, enhances fear and casts doubt on the potential of acute insomnia as a prophylactic measure against PTSD. Our findings bring into question the role of sleep in aversive-memory consolidation in clinical PTSD pathophysiology.

2013-10-01

Enhanced fear learning for fear-relevant stimuli has been demonstrated in procedures with adults in the laboratory. Three experiments investigated the effect of stimulus fear-relevance on vicarious fear learning in children (aged 6-11 years). Pictures of stimuli with different levels of fear-relevance (flowers, caterpillars, snakes, worms, and Australian marsupials) were presented alone or together with scared faces. In line with previous studies, children's fear beliefs and avoidance preferences increased for stimuli they had seen with scared faces. However, in contrast to evidence with adults, learning was mostly similar for all stimulus types irrespective of fear-relevance. The results support a proposal that stimulus preparedness is bypassed when children observationally learn threat-related information from adults.

Does Size Matter? Short and Tall Officers Policing the Streets

2013-04-01

Full Text Available The importance of physical characteristics is rarely addressed in the literature on professional competence and authority. In police work it is almost taken for granted that height is advantageous in police work, despite a lack of research on the topic. This study examines how height may affect police inter-actions with the public and how short and tall men and women experience the importance of their height in patrol work. Results show that being tall was perceived as beneficial in patrol work. Furthermore, the authority of short police officers is challenged more often by the public, and short female police may have a particular focus on verbal communication. Tallness will probably be perceived as beneficial in fields in which physical conflicts arises.

Calories and gastric emptying: a regulatory capacity with implications for feeding.

Science.gov (United States)

McHugh, P R; Moran, T H

1979-05-01

Gastric emptying in four unanesthetized male Macaca mulatta was studied with the serial test meal method of Hunt and Spurrell. Liquid meals were infused into the stomach through a chronic indwelling Silastic cannula. Saline meals empty rapidly and exponentially. Doubling the volume of saline from 150 to 300 ml increased the emptying rate so that the half-life remained unchanged (15 min). The 150-ml glucose meals (0.05, 0.125, and 0.25 g/ml) emptied more slowly than saline, progressively more slowly with increasing concentrations (0.05--1.8, 0.125--0.78, and 0.25--0.37 ml/min) and linearly through most of their course. Doubling the volume of 0.125 g/ml-glucose meal did not change the rate of emptying. Converting grams of glucose to their caloric content, the emptying rate in kcal/min becomes constant (approx 0.4 kcal/min) in this range of concentrations. Isocaloric casein hydrolysate and medium-chain triglyceride oil meals at 0.5 kcal/ml empty at the same rate as glucose. The precision of this regulation is sufficient to give it a role in preabsorptive satiety and the control of caloric intake.

Effect of anxiety on the rate of gastric emptying of liquids.

LENUS (Irish Health Repository)

Lydon, A

2012-02-03

The efficacy of preoperative fasting is reduced in the presence of any factor which delays gastric emptying. We examined the association between anxiety and gastric emptying in adult patients undergoing elective surgery. Immediately before operation, 21 patients completed both a Spielberger state trait inventory (used to quantify current anxiety state (STAIs) and anxiety predisposition (STAIt)), and the Amsterdam preoperative anxiety and information scale (used to quantify anxiety and need for information). Gastric emptying was measured using the paracetamol absorption technique. Four to 10 weeks later, gastric emptying and STAI were measured again. Patients were more anxious before than after operation (STAIs = mean 35.4 (SD 10.9) and 25 (4.1), respectively; P = 0.0004). Neither anxiety state (P = 0.40) nor measures of anxiety relative to anxiety predisposition (P = 0.86) influenced gastric emptying (as measured by area under the paracetamol absorption-time curve). This contrasts with previous findings that anxiety in patients with low anxiety predisposition scores delays gastric emptying.

Gastric emptying in patients with vitamin B{sub 12} deficiency

The clinical presentation of patients with vitamin B{sub 12} deficiency varies in a spectrum ranging from haematological disorders to neuropsychiatric diseases. In rare cases, orthostatic hypotension, impotence, constipation and urinary retention have been attributed to autonomic nervous system dysfunction due to vitamin B{sub 12} deficiency. The aim of this study was to evaluate the effect of vitamin B{sub 12} deficiency on autonomic nervous system function by studying gastric emptying times (T{sub 1/2}). Twenty patients with newly diagnosed vitamin B{sub 12} deficiency and 12 control patients with gastritis and normal vitamin B{sub 12} levels were enrolled in this study. Gastroduodenoscopy, endoscopic biopsy, histopathological evaluation of the biopsy specimens and radionuclide gastric emptying studies were performed. After vitamin B{sub 12} replacement therapy for 3 months, radionuclide gastric emptying studies were repeated. Mean gastric emptying T{sub 1/2} in patients before and after treatment and in controls were 103.83{+-}48.80 min, 90.00{+-}17.29 min and 74.55{+-}8.52 min, respectively. The difference in mean gastric emptying T{sub 1/2} between patients before treatment and controls was statistically significant (P<0.01). The statistically significant difference persisted after vitamin B{sub 12} treatment (P<0.05), though mean gastric emptying T{sub 1/2} was somewhat shorter. There were no positive or negative correlations between gastric emptying T{sub 1/2} and the following parameters: haemoglobin, vitamin B{sub 12} level and Helicobacter pylori positivity. In conclusion, gastric emptying T{sub 1/2} was prolonged in patients with vitamin B{sub 12} deficiency and this prolongation was not corrected after vitamin B{sub 12} replacement therapy. Although autonomic nervous system dysfunction due to vitamin B{sub 12} deficiency rarely gives rise to clinical manifestations, latent dysfunction demonstrated by laboratory tests seems to be a frequent phenomenon

Drug law enforcement subsumes the majority of drug policy expenditure across the globe. Fuelled by knowledge that much of this investment is ineffective or counter-productive there have been increasing calls for cross-national comparisons to identify where policing approaches differ and what types of approaches may be more effective. Yet, to date cross-national comparison of drug law enforcement has proven a methodologically hazardous affair. Using a new drug policing module added to the 2017 Global Drug Survey, this study seeks to provide the first cross-national comparison of the incidence, nature and intensity of illicit drug-related police encounters amongst people who use drugs. The Global Drug Survey was administered in late 2016. Across 26 countries including Australia, Germany, Italy, Mexico, Switzerland, the UK and the USA a total of 45,942 people who had recently used drugs completed the drug policing module. Key variables assessed included the incidence and frequency of drug-related police encounters in the last 12 months that involved: a) being stopped and searched; b) encountering a drug detection dog; c) being given a caution or warning; d) being charged and arrested; and e) paying a bribe. Multi-level models were used to control for pre-existing national differences in drug use prevalence and non-drug specific policing (including the total number of police personnel in each country). Drug-related police encounters were most commonly reported in Italy and Scotland. Conversely, police encounters were most likely to lead to arrest in Norway, Finland and Sweden. The type and locations of encounters further differed across countries, with for example stop and search most reported in Greece and Colombia, and encounters with drug detection dogs most reported in Scotland, Italy, UK and Australia. Multi-level models showed that the incidence of reported policing encounters continued to differ significantly across countries after controlling for pre

The effect of secretin at nearly physiologic plasma concentrations on the gastric emptying rate of solid food was studied in 12 healthy men. A /sup 99m/Tc colloid-labeled pancake was used as the test meal. The gastric emptying rate was measured during 1 h using a dual-headed gamma-camera, and was expressed as the half-time of the emptying curve. To prevent endogenous secretin release, 400 mg of cimetidine was given before the meal. Subjects were studied under three conditions: (1) during infusion of saline; (2) during continuous infusion of secretin, 6.6 pmol/kg.h; and (3) during three intermittent 10-min periods of secretin infusion, 7.6 pmol/kg.h during each period. Both continuous and intermittent infusion of secretin increased half-emptying time, by 133% and 55%, respectively. The plasma secretin concentration in condition 1 was 0.8 pM; plateau concentration in condition 2 was 9.8 pM; and integrated mean concentration in condition 3 was 4.8 pM. It is concluded that secretin at approximately physiologic plasma concentrations retards gastric emptying of solid food in humans.

Strategic restructuring for effective police system in Nigeria

2014-11-01

Full Text Available The success of a security outfit depends on the strategies and structure of the organisation. The study aims to unravel the possible ways of positioning the Nigerian Police force for effective service delivery through strategic restructuring. Nigerian police was instituted by the colonial authors on the threshold of oppression to achieve subjection and control. Upon this pattern of operation, the Nigerian police force lost the confidence of the public. To position this agency for desired performance, several changes should be made in the strategies and structure of the force, de-emphasizing on the issues that are no longer recent problems and emphasizing on the current bane of the nation, such as corruption and insecurity. This paper adopted the mono-method qualitative approach which made use of secondary sources of data collection. Findings, revealed that the department of the Force that was responsible for information and intelligent gathering, the CID has lied dormant for long a time due to lack of adequate structure as a background that will add value to the department. Furthermore, the force was bedevilled with poor information gathering due to lack of trust and confidence in the police force, the level of motivation was found to be low, as there were no insurance policies for the Force. It is thus obvious to note that the Nigerian police force has suitable strategies that are capable of a sustainable performance, but it is challenged by lack of corresponding structure to work out the strategies. The study proposed that one DIG in addition to the twelve DIGs should be integrated to man a department with the duty of developing and maintaining good relationship with the public, and providing EFCC, ICPC and other crime related agencies with the needed force in discharging their duties. Finally, there is a need for an upward review of the reward and compensation package of the Nigerian Police Force as a way of stepping up on motivation

Police investigations: discretion denied yet undeniably exercised

Police investigations involve determining whether a crime has been committed, and if so what type of crime, who has committed it and whether there is the evidence to charge the perpetrators. Drawing on fieldwork in Delhi and Mumbai, this paper explores how police investigations unfolded in the specific context of women’s deaths by burning in India. In particular, it focuses on the use of discretion despite its denial by those exercising it. In India, there are distinctive statutes relating to women’s suspicious deaths, reflecting the widespread expectation that the bride’s family will pay a dowry to the groom’s family and the tensions to which this may on occasion give rise in the early years of a marriage. Often, there are conflicting claims influencing how the woman’s death is classified. These in turn affect police investigation. The nature and direction of police discretion in investigating women’s deaths by burning reflect in part the unique nature of the legislation and the particular sensitivities in relation to these types of death. They also highlight processes that are liable to be at work in any crime investigation. It was found that police officers exercised unacknowledged discretion at seven specific points in the investigative process, with potentially significant consequences for the achievement of just outcomes: first response, recording the victim’s ‘dying declaration’, inquest, registering of the ‘First Information Report’, collecting evidence, arrest and framing of the charges.

Gastic emptying scan in diabetic patients is widely used to assess the degree of motility disturbance and the symptoms such as nausea, vomiting, bloating, abdominal pain and early gastric fullness which we can't find anatomic lesion by fiberoscopic or barium study. In order to determine the relationship among diabetic gastropathy, neropathy, retinopathy and disease duration, gastric emptying scan using 99m Tc-tin colloid labeled scramble egg in hamburger was performed in 10 healthy male controls and 50 diabetic patients which were subdivided to no neuropathy, peripheral neuropathy and autonomic neuropathy groups according to the degree of diabetic neuropathy and no retinopathy, background retinopathy and proliferative retinopathy groups according to the degree of diabetic retinopathy. After medication of cisapride for 2 weeks, we observed the presence of improvement of gastric motility in diabetics. The results were as following: 1) In controls, gastric emptying time (GET1/2) was 75 ± 13.6 min and 2 hour gastric retension rate(GRR2) was 32 ± 11.1%. 2) In diabetics, GET/2 was prolonged more than 2 hours and GRR2 was 58 ± 23.1%. According to degree of neuropathy, GET1/2 was prolonged more than 2 hours in all three groups and GRR2 was 54± 24.1% in no neuropathy group, 57 ± 24.3% in peripheral neuropathy group and 69 ± 24.6% in autonomic neuropathy group. According to degree of retinopathy, GET1/2 was 110 ± 23.4 min in no retinopathy group and prolonged more than 2 hours in other two groups and GRR2 was 45 ± 21.6% in no retinopathy group, 71 ± 19.7% in background retinopathy group and 73 ± 21.5% in proliferative retinopathy group. 3) After cisapride for 2 weeks, GET1/2 and GRR2 were improved as 90 ± 14.6 min and 40 ± 13.8% (initial GET1/2 and GRR2 were above 2 hours and 61 ± 15.4%).

Stereotype threat and racial differences in citizens' experiences of police encounters.

Science.gov (United States)

Najdowski, Cynthia J; Bottoms, Bette L; Goff, Phillip Atiba

2015-10-01

We conducted 2 studies to investigate how cultural stereotypes that depict Blacks as criminals affect the way Blacks experience encounters with police officers, expecting that such encounters induce Blacks to feel stereotype threat (i.e., concern about being judged and treated unfairly by police because of the stereotype). In Study 1, we asked Black and White participants to report how they feel when interacting with police officers in general. As predicted, Blacks, but not Whites, reported concern that police officers stereotype them as criminals simply because of their race. In addition, this effect was found for Black men but not Black women. In Study 2, we asked Black and White men to imagine a specific police encounter and assessed potential downstream consequences of stereotype threat. Consistent with Study 1, Black but not White men anticipated feeling stereotype threat in the hypothetical police encounter. Further, racial differences in anticipated threat translated into racial differences in anticipated anxiety, self-regulatory efforts, and behavior that is commonly perceived as suspicious by police officers. By demonstrating that Blacks might expect to be judged and treated unfairly by police because of the negative stereotype of Black criminality, this research extends stereotype threat theory to the new domain of criminal justice encounters. It also has practical implications for understanding how the stereotype could ironically contribute to bias-based policing and racial disparities in the justice system.

2014-12-01

The aim of this study is to examine the connection between gambling and criminal activity in the National Finnish Police Register. First, a method was created that enabled the search for gambling-related police reports in the National Finnish Police Register. The method is based on finding gambling-related police reports by using gambling-related headwords. Second, all police reports from 2011 that included any mention of gambling were read through (n = 2,233). Suspected gambling-related of crimes (n = 737) were selected from these reports. Those suspected gambling-related crimes were then described and categorized into six different categories: suspected online-related crimes; suspected crimes that were related to lifestyle-gaming; suspected crimes that involved a gambler as a victim of a crime; criminal activity related to problem gambling; casino-connected crimes, and intimate partnership violence resulting from gambling problems. This study, being the first in Finland, generated information on the connection between gambling and criminal activity from the perspective of police reports. Moreover, the study highlights methodological issues that are involved in studying police reports.

Police Responses to Persons With Mental Illness: Going Beyond CIT Training.

Science.gov (United States)

Steadman, Henry J; Morrissette, David

2016-10-01

Since 1988, a major development to reduce lethal encounters between police and persons displaying signs of mental illness has been the adoption by many police departments of crisis intervention teams (CITs). Created in Memphis, Tennessee, CIT programs incorporate deescalation training, police-friendly drop-off centers, and linkage to community treatment programs. The authors summarize issues discussed at a recent Substance Abuse and Mental Health Services Administration workshop at which participants highlighted the importance of going beyond CIT training to most effectively include police in a crisis care continuum model. Such an approach focuses on how police can be engaged as partners with behavioral health providers who are designing and implementing services in the crisis care continuum. Reframing the approach to police responses to persons in mental health crises offers the prospect of improving both public health and public safety goals.

Rape tactics, rape incident characteristics, and mental health problems (lifetime depression, PTSD, and substance abuse) were investigated as correlates of eight different reasons for not reporting a rape to police among women who had experienced but did not report a rape to police (n = 441) within a national telephone household probability sample. Rape tactics (nonmutually exclusive) included drug or alcohol-facilitated or incapacitated rape (DAFR/IR; n = 119) and forcible rape (FR; n = 376). Principal Components Analysis (PCA) was conducted to extract a dominant set of patterns among the eight reasons for not reporting, and to reduce the set of dependent variables. PCA results indicated three unique factors: Not Wanting Others to Know, Nonacknowledgment of Rape, and Criminal Justice Concerns. Hierarchical regression analyses showed DAFR/IR and FR were both positively and significantly associated with Criminal Justice Concerns, whereas DAFR/IR, but not FR, was associated with Nonacknowledgment as a reason for not reporting to police. Neither DAFR/IR nor FR emerged as significant predictors of Others Knowing after controlling for fear of death or injury at the time of the incident. Correlations among variables showed that the Criminal Justice Concerns factor was positively related to lifetime depression and PTSD and the Nonacknowledgement factor was negatively related to lifetime PTSD. Findings suggest prevention programs should educate women about the definition of rape, which may include incapacitation due to alcohol or drugs, to increase acknowledgement and decrease barriers to police reporting.

The purpose of these studies was to develop a radiologic method for assessing gastric emptying of an indigestible solid in humans and to apply this technique to the evaluation of patients with diabetes mellitus. Thirty healthy subjects ingested 10 solid radiopaque markers (small pieces of nasogastric tubing) together with a standard meal (donuts and 7-Up). Radiographs of the upper abdomen were obtained hourly for up to 6 h until all markers had emptied from the stomach. Although most of the liquid component of the meal, labeled with 111In, emptied during the first hour (as assessed simultaneously by radionuclide scintigraphy), few radiopaque markers emptied from the stomach during the first 2 h after the meal. Most markers emptied during the fourth postprandial hour, and all 10 markers had emptied by 6 h in 45 of 46 experiments. In contrast, not all of the solid radiopaque markers emptied from the stomach by 6 h in 16 of 26 experiments in patients with diabetes mellitus (p less than 0.001 vs. healthy controls). In some experiments, 99mTc-labeled scrambled eggs were added to the meal so that emptying of this digestible solid, assessed by scintigraphy, could be compared with emptying of liquids and solid radiopaque markers. In healthy subjects, the digestible solid emptied more slowly than the liquid (t 1/2 = 154 +/- 11 min vs. 30 +/- 3 min, p less than 0.001), but emptying of digestible solid was significantly faster than the emptying of the indigestible solid radiopaque markers. In diabetics, emptying rates for the digestible solid and liquid were close to normal (t 1/2 = 178 +/- 5 min and 40 +/- 3 min, respectively), whereas indigestible solid markers were retained in the stomach 6 h after the meal in 50% of the patients. Radiopaque markers proved to be a simple method for measuring gastric emptying of indigestible solids in humans. Using this technique, patients with insulin-dependent diabetes mellitus had a high incidence of abnormally slow gastric emptying of

EmptyHeaded: A Relational Engine for Graph Processing.

There are two types of high-performance graph processing engines: low- and high-level engines. Low-level engines (Galois, PowerGraph, Snap) provide optimized data structures and computation models but require users to write low-level imperative code, hence ensuring that efficiency is the burden of the user. In high-level engines, users write in query languages like datalog (SociaLite) or SQL (Grail). High-level engines are easier to use but are orders of magnitude slower than the low-level graph engines. We present EmptyHeaded, a high-level engine that supports a rich datalog-like query language and achieves performance comparable to that of low-level engines. At the core of EmptyHeaded's design is a new class of join algorithms that satisfy strong theoretical guarantees but have thus far not achieved performance comparable to that of specialized graph processing engines. To achieve high performance, EmptyHeaded introduces a new join engine architecture, including a novel query optimizer and data layouts that leverage single-instruction multiple data (SIMD) parallelism. With this architecture, EmptyHeaded outperforms high-level approaches by up to three orders of magnitude on graph pattern queries, PageRank, and Single-Source Shortest Paths (SSSP) and is an order of magnitude faster than many low-level baselines. We validate that EmptyHeaded competes with the best-of-breed low-level engine (Galois), achieving comparable performance on PageRank and at most 3× worse performance on SSSP.

Opioid overdose rates continue to rise at an alarming rate. One method used to combat this epidemic is the administration of naloxone by law enforcement. Many cities have implemented police naloxone administration programs, but there is a minimal amount of research examining this policy. The following study examines data over 18 months, after implementation of a police naloxone program in an urban setting. We describe the most common indications and outcomes of naloxone administration as well as examine the incidence of arrest, immediate detention, or voluntary transport to the hospital. In doing so, this study seeks to describe the clinical factors surrounding police use of naloxone, and the effects of police administration. All police officer administrations were queried from April 2014 through September 2015 (n = 126). For each incident we collected the indication, response, and disposition of the patient that was recorded on a "sick-injured civilian" report that officers were required to complete after administration of naloxone. All of the relevant information was abstracted from this report into an electronic data collection form that was then input into SPSS for analysis. The most common indication for administration was unconscious/unresponsive (n = 117; 92.9%) followed by slowed breathing (n = 72; 57.1%), appeared blue (n = 63; 50.0%) and not breathing (n = 41; 32.5%). After administration of naloxone the majority of patients regained consciousness (n = 82; 65.1%) followed by began to breath (n = 71; 56.3%). However, in 17.5% (n = 22) of the cases "Nothing" happened when naloxone was administered. The majority of patients were transported voluntarily to the hospital (n = 122; 96.8%). Lastly, there was only one report where the patient became combative. Our study shows that police officers trained in naloxone administration can correctly recognize symptoms of opioid overdose, and can appropriately administer naloxone without significant adverse effects or

Post-prandial upper abdominal symptoms such as nausea, fullness and early satiety in constipated children may be associated with delayed gastric emptying. Aim: To evaluate the gastric emptying in children with post-prandial upper abdominal symptoms. Materials and Methods: Gastric emptying studies were performed in 12 children with functional constipation (mean age 9 years; mean duration of symptoms: 5.5 years), fecal impaction and soiling. In 12 of them the studies were performed only before fecal impaction removal and in 7 of them the study was repeated after impaction removal and recovery from constipation. After an overnight fast, the patients received 300 ml/m 2 of water added to 37 MBq of 99m Tc-sulfur colloid. Images were acquired in a camera-computer system with a low energy all purpose collimator. Images were acquired at 1 minute per frame for 30 minutes. When gastric emptying was delayed for more than 30 minutes, additional static images with 500,000 counts were performed for no more than 1 hour until a T1/2 was obtained. Results: Gastric emptying was delayed (21.4 ± 7 minutes; normal 12 ± 3 minutes) in 10/12 patients studied prior to fecal impaction removal. In the group of seven patients who repeated the study after fecal impaction removal, gastric emptying remained prolonged (22 ±7.9 minutes). There was no statistically significant difference between the gastric emptying time before and after fecal impaction removal (p 0,612; Wilcoxon test). Conclusion: The gastric emptying time of a liquid test meal was delayed in constipated children before and after fecal impaction removal. Maintenance of prolonged emptying time after impaction removal and recovery from constipation may indicate an alteration in gastrointestinal motility

Policing and Islamophobia in Germany: The Role of Workplace Experience

Directory of Open Access Journals (Sweden)

Heidi Mescher

2008-06-01

Full Text Available This study starts from a recognition that the German police have a significant potential to promote integration in contemporary multiethnic Germany. It employs three measures of Islamophobic attitudes and contact quality amongst a sample of 727 German police officers, and relates these to measures of job satisfaction, political affiliation, individual responsibility, and recognition. The data reveal Islamophobia to be significantly linked to these variables. Detailed analyses indicate that the respondents’ experience of policing may produce levels of dissatisfaction that impacts upon their outgroup attitudes. The implications of this for initiatives to promote police-Muslim relations are explored.

Traffic policemen working in the busy traffic signal areas get exposed to the vehicular emissions for years together. The fumes, chemicals and particles present in the emission are reported to be damaging to the lung functions of these individuals. Since there were no data available on the PFT parameters of traffic police personnel of Pondicherry, this study was taken up to assess the effect of traffic air pollution on their pulmonary functions. PFT parameters were recorded in age- and BMI-matched 30 traffic police personnel (study group) and 30 general police personnel (control group) of male gender. As chronic smoking is known to be a critical factor in altering lung function, PFT parameters were compared between the smokers as well as nonsmokers of both the groups. In nonsmokers, there was significant decrease in VC (P traffic police personnel compared to the general police personnel. This may be due to exposure to vehicular pollution for several hours in a day for many years causing decreased functional capacity of the lungs and chronic smoking worsens the condition.

2016-01-01

Face recognition is used to prove identity across a wide variety of settings. Despite this, research consistently shows that people are typically rather poor at matching faces to photos. Some professional groups, such as police and passport officers, have been shown to perform just as poorly as the general public on standard tests of face recognition. However, face recognition skills are subject to wide individual variation, with some people showing exceptional ability-a group that has come to be known as 'super-recognisers'. The Metropolitan Police Force (London) recruits 'super-recognisers' from within its ranks, for deployment on various identification tasks. Here we test four working super-recognisers from within this police force, and ask whether they are really able to perform at levels above control groups. We consistently find that the police 'super-recognisers' perform at well above normal levels on tests of unfamiliar and familiar face matching, with degraded as well as high quality images. Recruiting employees with high levels of skill in these areas, and allocating them to relevant tasks, is an efficient way to overcome some of the known difficulties associated with unfamiliar face recognition.

1986-01-01

To evaluate gastric emptying, 20 patients with anorexia nervosa were given 150 μCi of Tc-99m triethylene tetraamine polystyrene resin in cereal and were imaged in the supine position. Data were accumulated at 5-minute intervals to determine the gastric emptying time (GET). The GET results were divided into three categories: prolonged (10 patients); rapid (eight); and normal (two). Although all patients had symptoms of gastric dysfunction, only 50% had prolonged GET. This study allows the objective documentation of gastric emptying and the separation of patients with rapid or normal GET from those with prolonged GET, who might benefit from metoclopramide

Policing is a stressful occupation and working in this environment may make officers more vulnerable to adverse psychological and physiological outcomes. The impact of prior military experience on work stress and coping strategies has not been well-studied in police. The purpose of this cross-sectional study was to examine differences in levels of police-related stress and coping in officers with and without military experience. Participants were 452 police officers from the Buffalo Cardio-metabolic Occupational Police Stress Study Officers were categorized into three groups: non-military (n = 334), non-combat military (n = 84), and military with combat (n = 34). Age, sex and education adjusted levels of psychological stress and coping measures were compared across the three groups using ANCOVA. P-values were derived from post-hoc comparisons. Non-military police officers had significantly higher stress levels for physically and psychological threatening events compared to non-combat officers (p = 0.019). Non-military officers also reported experiencing significantly more organizational stressors and physically and psychologically threatening events in the past year than combat and non-combat officers (p military officers (p = 0.010, p = 0.005, respectively). In summary, police officers without military experience reported experiencing more organizational and life-threatening events than officers who served in the military. Yet combat officers were less likely to utilize positive coping than non-combat and non-military officers. These findings demonstrate the potential positive influence of military experience on police stress. Further research is needed as military veterans return to police work.

1988-07-01

The effect of the new gastrokinetic agent cisapride on gastric emptying was evaluated in 17 dyspeptic patients using the dual radionuclide technique. Eight patients with idiopathic dyspepsia and nine postsurgical dyspeptic patients were studied and compared to a control group. Gastric emptying of solids and liquids was determined after ingestion of a standardized meal using 99mTc-sulfur colloid scrambled eggs as the solid phase and [111In]DTPA-labeled water as the liquid phase. Following a basal study and on a separate occasion, each patient received an intravenous bolus of 10 mg of cisapride after ingestion of the test meal; 10 of the patients were restudied after a two-week period of chronic oral administration of the drug (10 mg four times a day). Baseline gastric emptying of solids was significantly delayed in idiopathic and postsurgical patients; liquid emptying was only delayed in the postsurgical group. Intravenous and oral administration of cisapride significantly shortened gastric emptying in both groups. In all but one patient, the clinical improvement was confirmed by the test. Cisapride appears to be a good alternative to metoclopramide and domperiodone in the treatment of dyspeptic patients. The dual radionuclide technique appears to be a useful physiologic tool for evaluating and predicting the efficacy of a gastric prokinetic therapy in man.

Scintigraphic measurements of gastric emptying corrected for differences in tissue attenuation

Energy Technology Data Exchange (ETDEWEB)

Lauritzen, J.B.; Hoejgaard, L.; Uhrenholdt, A. (Copenhagen Univ. (Denmark). Hvidovre Hospital)

1983-10-01

In order to evaluate the importance of variations in tissue attenuation in scintigraphic measurements of gastric emptying, both in vivo and in vitro measurements of count rates from an encapsulated sup(99m)Tc dose were performed in different parts of the stomach. The obtained individual tissue correction factors were applied in the calculation of gastric emptying rates by gamma camera in healthy volunteers. The results showed that the anterior gamma camera scan without correction for differences in tissue attenuation underestimated the gastric emptying rate by 11% if the results were expressed as percentage meal emptied over 60 minutes.

Orlistat, an inhibitor of digestive lipases, is widely used for the treatment of obesity. Previous reports on the effect of orally ingested orlistat together with a meal on gastric emptying and secretion of gut peptides that modulate postprandial responses are controversial. We investigated...... the effect of ingested orlistat on gastric emptying and plasma responses of gut peptides in response to a solid mixed meal with a moderate energy load. In healthy subjects, gastric emptying was determined using scintigraphy and studies were performed without and with 120 mg of orlistat in pellet form......, implying that inhibition of fat absorption modifies determinants of gastric emptying of a meal. Orlistat administered similar to its use in obesity treatment accelerates gastric emptying of a solid mixed meal with a moderate energy load and profoundly attenuates release of GIP without appreciably altering...

You, Bo; Liu, Suju; Xu, Jun; Li, Dongjie

2007-11-01

Aimed at some typical constraints of police dogs and robots used in the areas of reconnaissance and counterterrorism currently, the multifunction anti-terrorism robotic system based on police dog has been introduced. The system is made up of two parts: portable commanding device and police dog robotic system. The portable commanding device consists of power supply module, microprocessor module, LCD display module, wireless data receiving and dispatching module and commanding module, which implements the remote control to the police dogs and takes real time monitor to the video and images. The police dog robotic system consists of microprocessor module, micro video module, wireless data transmission module, power supply module and offence weapon module, which real time collects and transmits video and image data of the counter-terrorism sites, and gives military attack based on commands. The system combines police dogs' biological intelligence with micro robot. Not only does it avoid the complexity of general anti-terrorism robots' mechanical structure and the control algorithm, but it also widens the working scope of police dog, which meets the requirements of anti-terrorism in the new era.

We developed a simple test meal for the evaluation of gastric emptying. Preparation of a test meal for routine clinical use in institutions should be as simple as possible. The newly developed test meal consists of instant noodles labeled with 37 MBq (1 mCi) technetium-99m and does not require the use of cooking utensils. The test meal was given with drinking water (180 ml) to healthy adult volunteers (6 men, 34.5[+-]2.2 years old) and gastric emptying was measured at 0, 5, 10, 15, 30, 45, 60, 80, 100, 120 minutes after the end of the meal, and results were compared with those derived without drinking water. The emptying pattern of the test meal with water exhibited an exponential pattern typical of a liquid meal, and that without water formed a linear pattern after an initial lag phase in keeping with gastric emptying of a solid meal. In addition, the test meal was given to 11 patients of diabetic gastroparesis (5 men, 6 women, 50.4[+-]4.5 years old), and gastric emptying was measured. At each period evaluated, emptying was significantly slower in diabetic gastroparesis than in healthy controls (6 men, 1 woman, 32.1[+-]3.0 years old). These results show that the test meal is reliable and applicable to the clinical assessment of gastric emptying, while fulfilling the need for simplicity. (author).

Adeno-associated virus (AAV) vectors have been successfully applied in clinical trials for hemophilic patients. Although promising, the clinical results suggest that the capsid-specific CD8+T cell response has a negative effect on therapeutic success. In an in vitro analysis using an engineered AAV virus carrying immune-dominant SIINFEKL peptide in the capsid backbone, we have previously demonstrated that capsid antigen presentation from full (genome containing) AAV capsids requires endosome escape and is proteasome dependent and that no capsid antigen presentation is induced from empty virions. In the present study, we examined capsid antigen presentation from administration of empty virions in animal models. In wild-type mice, similar to AAV full particles, capsid antigen presentation from AAV empty virion infection was dose dependent, and the kinetics studies showed that antigen presentation was detected from 2 to 40 days after AAV empty virion administration. In the transporter associated with antigen processing 1 deficient (TAP-/-) mice, capsid antigen presentation was inhibited from both AAV full and empty virions, but higher inhibition was achieved from AAV full particle administration than that from empty virions. This indicates that the pathway of capsid antigen presentation from AAV transduction is dependent on proteasome-mediated degradation of AAV capsids (mainly for full particles) and that the endosomal pathway may also play a role in antigen presentation from empty particles but not full virions. The capsid antigen presentation efficiency from AAV preparations was positively correlated with the amount of empty virions contaminated with full particles. Collectively, the results indicate that contamination of AAV empty virions induces efficient antigen presentation in vivo and the mechanism of capsid antigen presentation from empty virions involves both endosomal and proteasomal pathways. The elucidation of capsid antigen presentation from AAV empty

Measurement of gastric emptying during and between meal intake in free-feeding Lewis rats.

van der Velde, P; Koslowsky, I; Koopmans, H S

1999-02-01

A new scintigraphic measurement technique is described that allows accurate assessment of gastric emptying in between as well as during a number of successive meals. Measurements were made every minute of food intake, gastric nutrient filling, and gastric emptying over a 6 h, 40 min period in conscious, free-feeding, loosely restrained rats. Before receiving access to the food, the animals had been deprived for a period of 31 h. Over the full duration of the experiment, an average rate of gastric emptying of 2.46 +/- 0.18 (SE) kcal/h was established. During most meals, however, the gastric emptying rate was increased so that an average of 26.9 +/- 2.7% of the ingested calories was emptied while the animals were feeding, with an average emptying rate of 0.15 +/- 0.014 kcal/min or 8.88 +/- 0.84 kcal/h. This transient increase in the rate of gastric emptying was followed by a subsequent slowing of gastric emptying after meal termination; in the 10-min postmeal interval, an average emptying rate of 0.96 +/- 0.12 kcal/h was found. Despite these fluctuations during and immediately after meals, a relatively constant rate of caloric emptying is maintained over longer periods. There were no differences between the emptying rate during the first meal when the gastrointestinal tract was still empty, compared with later meals when the gastrointestinal tract had been filled with food. The emptying rate during the 10-min postmeal interval, however, was significantly reduced during later meals. The results suggest that gastric emptying is controlled by different mechanisms during and after the ingestion of food and that these mechanisms remain in effect at various degrees of gastrointestinal filling.

Judicial police, functions and its development in Albania

Directory of Open Access Journals (Sweden)

Asllan Dogjani

2016-03-01

Full Text Available This article aims at a consistent search of the opinions about the judicial police as one of the subjects, contained in the Albanian criminal procedural law. In article 30 of the Albanian Criminal Procedure Code, are sanctioned the functions, division, addiction and judicial police duties. In the initial phase, the preliminary investigations are the basis of criminal proceedings. This phase includes evidences that cannot be replicated, the security measures are set, it is performed the notice of suit and necessary datas are collected. Searching, tracking, capture and bringing before trial of the perpetrators is considered as one of the oldest activities of human being. The need to ensure these regulations and the aim to prevent the consequences of any criminal activity has forced societies and different states to establish special investigative bodies (investigation and to determine by time their rights and obligations. So judicial police organs were provided and charged with competences and legal responsibility for the detection, crime preventions and research, capturing and bringing before the court, individuals or groups who commit criminal activities. From a comparative overview of legislation of the judicial police in several countries around the world, it is shown that there is no extreme change in structures and organizational patterns of these bodies, missions, powers and responsibilities they exercise (Elezi, 1997, 13. Judicial police in Albania has also been and is one of the important subjects of the criminal proceedings. In the historical perspective these bodies have had mixed origins and nature, and in different times they were military or civilian institutions. In this context, main purpose of this paper is the analysis of judicial police in

The primary empty sella in children and its significance

Tokiguchi, Susumu; Tsuchiya, Toshiaki; Ito, Jusuke

1983-01-01

The primary empty sella has been thought to be rare in children; only a few children have been described in the literature. The majority of such cases have been associated with congenital anomalies, optic atrophies, or cerebrospinal fluid rhinorrheas. We now report four cases of the primary empty sella in children. Two of the patients(Case 1 and Case 3) were prepubescent and had primary generalized epilepsy, while Case 2 and Case 4 complained of attacks of vascular headache and peri-orbital pain respectively. None of them showed any clinical evidence of endocrine disturbance. Ophthalmological examination revealed no abnormalities. The association of the primary empty sella with such disorders as primary epilepsy, attacks of vascular headache, and peri-orbital pain were thought to be almost certainly coincidental; the possibility was suggested that the empty sella might be present in children as an anatomical variant or as an acquired process in a certain percentage of them.

'May issue' gun carrying laws and police discretion: Some evidence from Massachusetts.

Science.gov (United States)

Hemenway, David; Hicks, James G

2015-08-01

In almost all states in the United States, to carry a concealed handgun legally requires a permit from the police. Many states have changed from may-issue laws (where the local police chief has discretion about to whom to issue a license) to shall-issue laws (where the police chief must issue a permit if the applicant passes a computerized federal background check). Studies conflict on the effect on crime. None considered the situation in may-issue states when police used discretion and refused to issue a permit. We provide suggestive evidence from a December 2013 survey of police chiefs in Massachusetts' 351 cities and towns. Of the 121 responding police chiefs, a large majority favored retaining police discretion. Chiefs issued few discretionary denials - median 2 per year, citing providing false information, a history of assault (often domestic violence), a history of drug or alcohol abuse, or of mental-health issues as the most common reasons for denial.

Full Text Available There is an appearance that women are uninterested in applying for positions in specialist areas of policing such as tactical operations, traffic and highway patrol, and counterterrorism. It cannot be assumed however that the low numbers of women is indicative of a lack of interest or will to be involved in these areas as there may be unidentified structural impediments preventing them from gaining access to these jobs. This paper critically discusses the issues relevant to women’s involvement in specialist policing roles and what can be done by police leaders to encourage greater employment of women in specialist policing roles.

Fear of acquired immunodeficiency syndrome and fear of other illness in suicide

DEFF Research Database (Denmark)

Aro, A R; Jallinoja, P T; Henriksson, M M

1994-01-01

Suicide victims with fear of acquired immunodeficiency syndrome (AIDS) or other somatic illness were compared for psychosocial and health-related characteristics, triggers and content of fear. Fear of AIDS cases (n = 28), 2% of the 1-year Finnish suicide population (n = 1397), were younger...... and fewer had serious somatic disease (32% vs 64%) compared with cases of fear of other somatic illness. Both groups had more depression, especially major depression (54% and 61% vs 26%), more psychotic disorders (50% and 32% vs 24%) and health care contacts during their final week (61% and 64% vs 36%) than...... other suicides. Suicidal fear of AIDS calls for evaluation of sexual and other risk behaviour, but fear of AIDS was largely generated by the extensive media coverage. Fear of other somatic illness was more diverse in origin and related to illness experiences. Suicidal fear of illness calls...

Evaluation of functional scintigraphy of gastric emptying by the principal component method

Energy Technology Data Exchange (ETDEWEB)

Haeussler, M.; Eilles, C.; Reiners, C.; Moll, E.; Boerner, W.

1980-10-01

Gastric emptying of a standard semifluid test-meal, labeled with /sup 99/sup(m)Tc-DTPA, was studied by functional scintigraphy in 88 subjects (normals, patients with duodenal and gastric ulcer before and after selective proximal vagotomy with and without pyloroplasty). Gastric emptying curves were analysed by the method of principal components. Patients after selective proximal vagotomy with pyloroplasty showed an rapid initial emptying, whereas this was a rare finding in patients after selective proximal vagotomy without pyloroplasty. The method of principal components is well suited for mathematical analysis of gastric emptying; nevertheless the results are difficult to interpret. The method has advantages when looking at larger collectives and allows a separation into groups with different gastric emptying.

The Shadow of Physical Harm? Examining the Unique and Gendered Relationship Between Fear of Murder Versus Fear of Sexual Assault on Fear of Violent Crime.

Science.gov (United States)

Riggs, Samantha; Cook, Carrie L

2015-09-01

The shadow hypothesis regarding the impact of fear of sexual assault on fear of violent crime suggests that female fear of crime is characterized by concern about sexual assault as a contemporaneous victimization event during a violent crime event. Recent research has found that other types of crime, namely physical assault, may also be feared as a contemporaneous offense. We know of no research that has examined the unique impact of fear of murder versus fear of sexual assault on fear of violent crime. There is also a lack of research that explores how these two types of fear uniquely affect men and women. In addition to gender, we examine factors that have been suggested in previous research to correlate with fear of crime: race, victimization, vicarious victimization, and perceived risk. Through survey methodology, this research examines the unique relationship between both fear of murder and fear of sexual assault and fear of three types of violent crime for men and women. Results suggest differences in how fear of murder and fear of sexual assault are related to fear of other types of violence for men and women. Specifically, fear of murder is important in estimating male fear of robbery and aggravated assault. However, fear of sexual assault is almost as important as fear of murder for men in estimating fear of home invasion. Similarly, for women, fear of sexual assault and fear of murder both are significant factors associated with fear of violent crime, and differences between the levels of significance are marginal. This study is a first to examine whether murder may also be feared as a contemporaneous offense. The results are informative in identifying what drives fear of crime, particularly violent crime, for both men and women. Avenues for future research are discussed. © The Author(s) 2014.

Police on the Front Line of Community Geriatric Healthcare: Challenges and Opportunities

Science.gov (United States)

Brown, Rebecca T.; Ahalt, Cyrus; Steinman, Michael A.; Kruger, Kelly; Williams, Brie A.

2015-01-01

As the population ages, police increasingly serve as first responders to incidents involving older adults in which aging-related health plays a critical role. The goals of this study were to assess police officers’ knowledge of aging-related health; to identify challenges police experience in their encounters with older adults; and to describe their recommendations for how to address those challenges. This was a mixed methods study of 141 San Francisco police officers recruited from mandatory police trainings between 2011 and 2013. Descriptive statistics were used to analyze 141 self-administered questionnaires and principles of grounded theory were used to analyze open-ended questionnaire responses and 11 additional qualitative interviews. Nearly all officers (89%) reported interacting with older adults at least monthly. Although 84% of police reported prior training in working with older adults, only 32% rated themselves knowledgeable about aging-related health. Participants described themselves as first-responders to medical and social emergencies involving older adults and identified several challenges including identifying and responding to aging-related conditions and ensuring appropriate medical and social service hand-offs. To address these challenges, officers recommended developing trainings focused on recognizing and responding to aging-related conditions and improving police knowledge of community resources for older adults. They also called for enhanced communication and collaboration between police and clinicians. These findings suggest that despite playing a front-line role in responding to older adults with complex medical and social needs, many police may benefit from additional knowledge about aging-related health and community resources. Collaboration between police and healthcare providers presents an important opportunity to develop geriatrics training and interprofessional systems of care to support police work with a rapidly aging

Do processes for training future police officers improve their mental health?

Directory of Open Access Journals (Sweden)

Miguel Clemente

Full Text Available The selection and training of future police officer candidates are two fundamental processes in achieving an effective police force. From a psychological point of view, police officer training should improve candidates' mental health, so that they can perform their police work more appropriately, benefiting not only themselves but society as a whole. This article attempts to determine whether the training given to candidates selected for training prior to being selected as officers improves their mental health. There is no precedent for research in this regard, since work in Psychology has focused on verifying that subjects do not have psychological pathologies rather than examining the effect of the training they are given. This study looks at a sample of 713 persons selected for a pre-police training program designed to allow them to subsequently join the Peruvian police force. The Derogatis SCL-90 test was used as a personality measure. The test was administered before they received training and after they had completed it (only data from subjects who passed the police entrance exam were considered. The results indicate that the training process produced no changes in personality variables that imply major psychological pathologies, but such changes did occur in variables associated with lower degree psychological pathologies. We can therefore say that there was a decline in mental health among future police officers, or an increase in their psychological pathologies. We will discuss these results and identify the limitations of the study with an eye toward further research. It is recommended that training systems be created that improve the mental health of future police officers.

Solid Test Meal to Measure the Gastric Emptying with Magnetogastrography

International Nuclear Information System (INIS)

Reynaga-Ornelas, M. G.; Roca-Chiapas, J. M. de ls; Cordova-Fraga, T.; Bernal, J. J.; Sosa, M.

2008-01-01

The gastric emptying is the time of evacuating the food ingested from the stomach to the duodenum in a controlled rate. Diverse studies express the results of the gastric emptying in form of half-time (t 1/2 ). The Magnetogastrography (MGG) is a biomagnetic technique that has the advantage of not being invasive, radiation free and does not interfere with the privacy of the subject. The objective was to analyze the magnetic signal of magnetic tracers mixed in a solid food to measure gastric emptying using Magnetogastrography. The ingested test meal displayed a magnetic signal, which served to obtain the signal registered by the fluxgate and the peristaltic contractions could be calculated while the stomach was emptying. The solid food product developed results to work satisfactorily in magnetogastrography

Behaviour of police officials towards mentally ill persons

Directory of Open Access Journals (Sweden)

Damir Juras

2014-01-01

Full Text Available The authors demonstrate the behaviour of police towards mentally ill individuals de lege lata and de lege ferenda. For this, they use an analysis of the existing Protection and Advocacy for the Mentally Ill Act, the draft of the new law which regulates that area, examples from practice, statistical data and the viewpoints of the legal and medical professions. This article points out the most frequent application of police powers when dealing with mentally ill persons and certain quandaries about the practice of admitting mentally ill persons into psychiatric institutions when they are a danger to themselves and others, that is, in the case of providing help to health workers dealing with mentally ill persons. Statistical data for the area of the Republic of Croatia point to a slight trend in the increase of police interventions over the last five years and also in the professional police approach towards such individuals. In conclusion, the coordinated activity of all services dealing with mentally ill persons is proposed as are additional education and the specialisation of police officials dealing with such persons. Furthermore, the need for balance between the necessity to protect the rights of mentally ill persons and the protection of rights and the security of the surroundings in which such persons live and the security of the entire community are pointed out.

Fear of Terrorism in New York After the September 11 Terrorist Attacks: Implications for Emergency Mental Health and Preparedness

Science.gov (United States)

Boscarino, Joseph A.; Figley, Charles R.; Adams, Richard E.

2009-01-01

To examine the public’s response to future terrorist attacks, we surveyed 1,001 New Yorkers in the community one year after the September 11 attacks. Overall, New Yorkers were very concerned about future terrorist attacks and also concerned about attacks involving biological or nuclear weapons. In addition, while most New Yorkers reported that if a biological or nuclear attack occurred they would evaluate available information before evacuating, a significant number reported they would immediately evacuate, regardless of police or public health communications to the contrary. The level of public concern was significantly higher on all measures among New York City and Long Island residents (downstate) compared to the rest of the state. A model predicting higher fear of terrorism indicated that downstate residents, women, those 45 to 64 years old, African Americans and Hispanics, those with less education/income, and those more likely to flee, were more fearful of future attacks. In addition, making disaster preparations and carefully evaluating emergency information also predicted a higher level of fear as well. A second model predicting who would flee suggested that those more likely to evaluate available information were less likely to immediately evacuate, while those with a higher fear of future attacks were more likely to flee the area. Given these findings and the possibility of future attacks, mental health professionals need to be more involved in preparedness efforts, especially related to the psychological impact of attacks involving weapons of mass destruction.

Community Policing in Mexico The Framework of Resistance and Conditions of Possibility

Directory of Open Access Journals (Sweden)

Alejandro Fontecilla Pinto

2014-12-01

Full Text Available The complex environment of insecurity, violence and crime that characterizes Mexico today renders traditional crime fighting, based exclusively on police reaction and an inquisitorial criminal system, ineffective. This was the only answer to all types of crimes for decades. For this reason, from 2011 INSYDE has been participating and exploring, in partnership with various government forces and determined voices, new ways of implementing community policing actions in Mexico and promoting reconciliation and police-community proximity. They have been encouraged by the firm conviction of the importance of our legitimate human right to safety and our desire for a more democratic, modern and citizen-focused police. This paper explores some of the findings and challenges that the community policing model presents in Mexico in order to find a place in preventive police forces.

Study objective Two decades ago, Philadelphia began allowing police transport of patients with penetrating trauma. We conduct a large, multiyear, citywide analysis of this policy. We examine the association between mode of out-of-hospital transport (police department versus emergency medical services [EMS]) and mortality among patients with penetrating trauma in Philadelphia. Methods This is a retrospective cohort study of trauma registry data. Patients who sustained any proximal penetrating trauma and presented to any Level I or II trauma center in Philadelphia between January 1, 2003, and December 31, 2007, were included. Analyses were conducted with logistic regression models and were adjusted for injury severity with the Trauma and Injury Severity Score and for case mix with a modified Charlson index. Results Four thousand one hundred twenty-two subjects were identified. Overall mortality was 27.4%. In unadjusted analyses, patients transported by police were more likely to die than patients transported by ambulance (29.8% versus 26.5%; OR 1.18; 95% confidence interval [CI] 1.00 to 1.39). In adjusted models, no significant difference was observed in overall mortality between the police department and EMS groups (odds ratio [OR] 0.78; 95% CI 0.61 to 1.01). In subgroup analysis, patients with severe injury (Injury Severity Score >15) (OR 0.73; 95% CI 0.59 to 0.90), patients with gunshot wounds (OR 0.70; 95% CI 0.53 to 0.94), and patients with stab wounds (OR 0.19; 95% CI 0.08 to 0.45) were more likely to survive if transported by police. Conclusion We found no significant overall difference in adjusted mortality between patients transported by the police department compared with EMS but found increased adjusted survival among 3 key subgroups of patients transported by police. This practice may augment traditional care. PMID:24387925

JSC furnished information on lighting and other fatigue reducing measures, and provided specifications for equipment and design layouts. JSC also advised OCPD how to avoid communications bottlenecks associated with simultaneous handling of telephone, radio and inner-office transmissions. Oklahoma City saved money in reduced design and engineering costs by utilizing the already developed NASA technology.

Police officers' collaboration with rape victim advocates: barriers and facilitators.

Science.gov (United States)

Rich, Karen; Seffrin, Patrick

2013-01-01

Secondary victimization may occur when rape victims make police reports. This can compromise the quality of official statements and jeopardize criminal cases. Rape reporters receive better treatment by police officers when advocates are involved and best practice police work includes such collaboration. Studies of advocates have described tension, role confusion, and poor communication with police officers. Many variables, including rape myth acceptance (RMA) and training on sexual assault dynamics, may affect officers' collaboration with advocates. There were 429 police officers who responded to a survey measuring their victim interviewing skill, formal training about rape, years on the job, number of victims known personally, number of recent rape cases, RMA, and collaboration with advocates. Results suggest that officers' interviewing skill, years on the job, and specific training are related to collaboration with victim advocates on rape cases. Professional, rather than personal, variables were most predictive of collaboration. Implications for officer selection and training are explored.

Harm reduction and law enforcement in Vietnam: influences on street policing

Science.gov (United States)

2012-01-01

Background and rationale The HIV epidemic in Vietnam has from its start been concentrated among injecting drug users. Vietnam instituted the 2006 HIV/AIDS Law which includes comprehensive harm reduction measures, but these are unevenly accepted and inadequately implemented. Ward police are a major determinant of risk for IDUs, required to participate in drug control practices (especially meeting quotas for detention centres) which impede support for harm reduction. We studied influences on ward level police regarding harm reduction in Hanoi to learn how to better target education and structural change. Methods After document review, we interviewed informants from government, NGOs, INGOs, multilateral agencies, and police, using semi-structured guides. Topics covered included perceptions of harm reduction and the police role in drug law enforcement, and harm reduction training and advocacy among police. Results Police perceive conflicting responsibilities, but overwhelmingly see their responsibility as enforcing drug laws, identifying and knowing drug users, and selecting those for compulsory detention. Harm reduction training was very patchy, ward police not being seen as important to it; and understanding of harm reduction was limited, tending to reflect drug control priorities. Justification for methadone was as much crime prevention as HIV prevention. Competing pressures on ward police create much anxiety, with performance measures based around drug control; recourse to detention resolves competing pressures more safely. There is much recognition of the importance of discretion, and much use of it to maintain good social order. Policy dissemination approaches within the law enforcement sector were inconsistent, with little communication about harm reduction programs or approaches, and an unfounded assumption that training at senior levels would naturally reach to the street. Discussion Ward police have not been systematically included in harm reduction advocacy

POLICE OFFICE MODEL IMPROVEMENT FOR SECURITY OF SWARM ROBOTIC SYSTEMS

Directory of Open Access Journals (Sweden)

I. A. Zikratov

2014-09-01

Full Text Available This paper focuses on aspects of information security for group of mobile robotic systems with swarm intellect. The ways for hidden attacks realization by the opposing party on swarm algorithm are discussed. We have fulfilled numerical modeling of potentially destructive information influence on the ant shortest path algorithm. We have demonstrated the consequences of attacks on the ant algorithm with different concentration in a swarm of subversive robots. Approaches are suggested for information security mechanisms in swarm robotic systems, based on the principles of centralized security management for mobile agents. We have developed the method of forming a self-organizing information security management system for robotic agents in swarm groups implementing POM (Police Office Model – a security model based on police offices, to provide information security in multi-agent systems. The method is based on the usage of police station network in the graph nodes, which have functions of identification and authentication of agents, identifying subversive robots by both their formal characteristics and their behavior in the swarm. We have suggested a list of software and hardware components for police stations, consisting of: communication channels between the robots in police office, nodes register, a database of robotic agents, a database of encryption and decryption module. We have suggested the variants of logic for the mechanism of information security in swarm systems with different temporary diagrams of data communication between police stations. We present comparative analysis of implementation of protected swarm systems depending on the functioning logic of police offices, integrated in swarm system. It is shown that the security model saves the ability to operate in noisy environments, when the duration of the interference is comparable to the time necessary for the agent to overcome the path between police stations.

To diagnose the occurrence and stage of stress among military police enlisted personnel and officers in the city of Natal (the capital of the state of Rio Grande do Norte, Brazil), and to determine the prevalence of physical and mental symptoms. This cross-sectional descriptive study investigated a sample of 264 individuals from a population of 3,193 military personnel from the Natal police command. The data were collected between June 2004 and January 2005 using Lipp's Adult Stress Symptoms Inventory (Inventário de Sintomas de Stress para Adultos de Lipp). The research assessed: (1) presence of stress, (2) the stage of stress (alert, resistance, near-burnout, and burnout), (3) the prevalence of physical and mental symptoms, and (4) the relationship between stress and police unit, rank, gender, drinking, smoking, educational level, marital status, age, years of police service, and salary. No stress symptoms were found in 52.6% of the sample; 47.4% had symptoms. Of the 47.4% of the police personnel with stress symptoms, they were distributed as: 3.4% in the alert stage, 39.8% in the resistance stage, 3.8% in the near-burnout stage, and 0.4% in the burnout stage. Psychological symptoms were recorded in 76.0% of the police personnel with stress, and physical symptoms in 24.0% of them. Of the variables investigated, only gender was related to stress (P = 0.0337), with the female police personnel being more likely to suffer from stress. The levels of stress and symptoms do not indicate a critical situation of fatigue. However, it is recommended that the police take preventive actions, including implementing an effective program for the diagnosis of, training on, and control of stress.

Internal Affairs Sector: Towards a new Law on Police

Directory of Open Access Journals (Sweden)

Radivojević Nenad P.

2015-01-01

Full Text Available By establishing the Inspector General's Service within the Department of Public Safety in 2001, Serbia became one of the countries that have institutionalized internal control of the police. By the adoption of the Law on Police in 2005, the name of the Service was renamed in the Internal Affairs Sector. Ten years of work of the Internal Affairs Sector revealed the existence of certain problems because of a inadequate and not complete legal framework. That was, among other, the reason for initiating the adoption of the new Law on Police. This paper presents solutions of the Draft Law on Police, in part related to the work of the Sector. The Draft contains some new solutions that could improve the efficiency of the Sector, but some doubts and uncertainties still remain, that will also be explained in this paper.

1988-01-01

The effect of the new gastrokinetic agent cisapride on gastric emptying was evaluated in 17 dyspeptic patients using the dual radionuclide technique. Eight patients with idiopathic dyspepsia and nine postsurgical dyspeptic patients were studied and compared to a control group. Gastric emptying of solids and liquids was determined after ingestion of a standardized meal using /sup 99m/Tc-sulfur colloid scrambled eggs as the solid phase and [ 111 In]DTPA-labeled water as the liquid phase. Following a basal study and on a separate occasion, each patient received an intravenous bolus of 10 mg of cisapride after ingestion of the test meal; 10 of the patients were restudied after a two-week period of chronic oral administration of the drug (10 mg four times a day). Baseline gastric emptying of solids was significantly delayed in idiopathic and postsurgical patients; liquid emptying was only delayed in the postsurgical group. Intravenous and oral administration of cisapride significantly shortened gastric emptying in both groups. In all but one patient, the clinical improvement was confirmed by the test. Cisapride appears to be a good alternative to metoclopramide and domperiodone in the treatment of dyspeptic patients. The dual radionuclide technique appears to be a useful physiologic tool for evaluating and predicting the efficacy of a gastric prokinetic therapy in man

Gastric emptying of solid radiopaque markers: studies in healthy subjects and diabetic patients

International Nuclear Information System (INIS)

Feldman, M.; Smith, H.J.; Simon, T.R.

1984-01-01

The purpose of these studies was to develop a radiologic method for assessing gastric emptying of an indigestible solid in humans and to apply this technique to the evaluation of patients with diabetes mellitus. Thirty healthy subjects ingested 10 solid radiopaque markers (small pieces of nasogastric tubing) together with a standard meal (donuts and 7-Up). Radiographs of the upper abdomen were obtained hourly for up to 6 h until all markers had emptied from the stomach. In some experiments, 99mTc-labeled scrambled eggs were added to the meal so that emptying of this digestible solid, assessed by scintigraphy, could be compared with emptying of liquids and solid radiopaque markers. In healthy subjects, the digestible solid emptied more slowly than the liquid (t 1/2 . 154 +/- 11 min vs. 30 +/- 3 min, p less than 0.001), but emptying of digestible solid was significantly faster than the emptying of the indigestible solid radiopaque markers. In diabetics, emptying rates for the digestible solid and liquid were close to normal (t 1/2 . 178 +/- 5 min and 40 +/- 3 min, respectively), whereas indigestible solid markers were retained in the stomach 6 h after the meal in 50% of the patients. Radiopaque markers proved to be a simple method for measuring gastric emptying of indigestible solids in humans. Using this technique, patients with insulin-dependent diabetes mellitus had a high incidence of abnormally slow gastric emptying of indigestible solids; the method may be a more sensitive indicator of gastric motor dysfunction than radionuclide scintigraphy

The purpose of these studies was to develop a radiologic method for assessing gastric emptying of an indigestible solid in humans and to apply this technique to the evaluation of patients with diabetes mellitus. Thirty healthy subjects ingested 10 solid radiopaque markers (small pieces of nasogastric tubing) together with a standard meal (donuts and 7-Up). Radiographs of the upper abdomen were obtained hourly for up to 6 h until all markers had emptied from the stomach. In some experiments, 99mTc-labeled scrambled eggs were added to the meal so that emptying of this digestible solid, assessed by scintigraphy, could be compared with emptying of liquids and solid radiopaque markers. In healthy subjects, the digestible solid emptied more slowly than the liquid (t 1/2 . 154 +/- 11 min vs. 30 +/- 3 min, p less than 0.001), but emptying of digestible solid was significantly faster than the emptying of the indigestible solid radiopaque markers. In diabetics, emptying rates for the digestible solid and liquid were close to normal (t 1/2 . 178 +/- 5 min and 40 +/- 3 min, respectively), whereas indigestible solid markers were retained in the stomach 6 h after the meal in 50% of the patients. Radiopaque markers proved to be a simple method for measuring gastric emptying of indigestible solids in humans.

We developed a simple test meal for the evaluation of gastric emptying. Preparation of a test meal for routine clinical use in institutions should be as simple as possible. The newly developed test meal consists of instant noodles labeled with 37 MBq (1 mCi) technetium-99m and does not require the use of cooking utensils. The test meal was given with drinking water (180 ml) to healthy adult volunteers (6 men, 34.5±2.2 years old) and gastric emptying was measured at 0, 5, 10, 15, 30, 45, 60, 80, 100, 120 minutes after the end of the meal, and results were compared with those derived without drinking water. The emptying pattern of the test meal with water exhibited an exponential pattern typical of a liquid meal, and that without water formed a linear pattern after an initial lag phase in keeping with gastric emptying of a solid meal. In addition, the test meal was given to 11 patients of diabetic gastroparesis (5 men, 6 women, 50.4±4.5 years old), and gastric emptying was measured. At each period evaluated, emptying was significantly slower in diabetic gastroparesis than in healthy controls (6 men, 1 woman, 32.1±3.0 years old). These results show that the test meal is reliable and applicable to the clinical assessment of gastric emptying, while fulfilling the need for simplicity. (author)

To assess depression literacy, help-seeking and help-offering to others in members of the police force in the state of Victoria, Australia. All staff in police stations involved in a cluster randomised controlled trial of an integrated workplace mental health intervention were invited to participate. Survey questions covered sociodemographic and employment information, recognition of depression in a vignette, stigma, treatment beliefs, willingness to assist co-workers with mental health problems, help-giving and help-seeking behaviours, and intentions to seek help. Using the baseline dataset associated with the trial, the paper presents a descriptive analysis of mental health literacy and helping behaviours, comparing police station leaders and lower ranks. Respondents were 806 staff, comprising 618 lower-ranked staff and 188 leaders. Almost 84% of respondents were able to correctly label the problem described in the vignette. Among those who had helped someone with a mental health problem, both lower ranks and leaders most commonly reported 'talking to the person' although leaders were more likely to facilitate professional help. Leaders' willingness to assist the person and confidence in doing so was very high, and over 80% of leaders appropriately rated police psychologists, general practitioners, psychologists, talking to a peer and contacting welfare as helpful. However, among both leaders and lower ranks with mental health problems, the proportion of those unlikely to seek professional help was greater than those who were likely to seek it. Knowledge about evidence-based interventions for depression was lower in this police sample than surveys in the general population, pointing to the need for education and training to improve mental health literacy. Such education should also aim to overcome barriers to professional help-seeking. Interventions that aim to improve mental health literacy and help-seeking behaviour appear to be suitable targets for better

Full Text Available Attentional control (AC and fear extinction learning are known to be involved in pathological anxiety. In this study we explored whether individual differences in non-emotional AC were associated with individual differences in the magnitude and gradient of fear extinction (learning and recall. In 50 individuals with fear of spiders, we collected measures of non-emotional AC by means of self-report and by assessing the functioning of the major attention networks (executive control, orienting, and alerting. The participants then underwent a paradigm assessing fear extinction learning and extinction recall. The two components of the orienting network functioning (costs and benefits were significantly associated with fear extinction gradient over and above the effects of trait anxiety. Specifically, participants with enhanced orienting costs (i.e., difficulties in disengaging attention from cues not relevant for the task showed faster extinction learning, while those with enhanced orienting benefits (i.e., attention facilitated by valid cues exhibited faster extinction recall as measured by fear-potentiated startle and Unconditioned Stimulus expectancies, respectively. Our findings suggest that, in non-emotional conditions, the orienting component of attention may be predictive of fear extinction. They also show that the use of fear extinction gradients and the exploration of individual differences in non-emotional AC (using performance-based measures of attentional network functioning can provide a better understanding of individual differences in fear learning. Our findings also may help to understand differences in exposure therapy outcomes.

Consumption of empty calories, the sum of energy from added sugar and solid fat, exceeds recommendations, but little is known about where US children obtain these empty calories. The objectives of this study were to compare children's empty calorie consumption from retail food stores, schools, and fast food restaurants; to identify food groups that were top contributors of empty calories from each location; and to determine the location providing the majority of calories for these key food groups. This cross-sectional analysis used data from 3,077 US children aged 2-18 years participating in the 2009-2010 National Health and Nutrition Examination Survey. The empty calorie content of children's intake from stores (33%), schools (32%), and fast food restaurants (35%) was not significantly different in 2009-2010. In absolute terms, stores provided the majority of empty calorie intake (436 kcal). The top contributors of added sugar and solid fat from each location were similar: sugar sweetened beverages (SSBs), grain desserts, and high-fat milk from stores; high-fat milk, grain desserts, and pizza from schools; and SSBs, dairy desserts, french fries, and pizza from fast food restaurants. Schools contributed about 20% of children's intake of high-fat milk and pizza. In conclusion, these findings support the need for continued efforts to reduce empty calorie intake among US children aimed not just at fast food restaurants, but also at stores and schools. The importance of reformed school nutrition standards was suggested, as prior to their implementation, schools resembled fast food restaurants in their contributions to empty calorie intake.

Police officers have a higher risk for cardiovascular disease. Reductions in occupational physical activity may contribute to the risk, yet there have been few efforts to characterize the physical demands of police work beyond self-report. To compare measured physical activity between work and off-duty hours and assess the effects of stress on physical activity. Officers (n = 119) from six departments wore a pattern recognition monitor for 96 hours to measure total energy expenditure (kilocalorie per hour) (1k/cal = 4184 joules), activity intensity, and step count per hour. Participants were more active on their off-duty days than at work; the effects of stress on physical activity seemed moderated by sex. Police work is primarily a sedentary occupation, and officers tend to be more active on their off-duty days than during their work hours.

Delayed postoperative gastric emptying following intrathecal morphine and intrathecal bupivacaine.

Lydon, A M

2012-02-03

PURPOSE: A decrease in the rate of gastric emptying can delay resumption of enteral feeding, alter bioavailability of orally administered drugs, and result in larger residual gastric volumes, increasing the risk of nausea and vomiting. We compared the effects of 1) intrathecal bupivacaine (17.5 mg) and 2) the combination of intrathecal morphine (0.6 mg) and intrathecal bupivacaine (17.5 mg) on the rate of gastric emptying in patients undergoing elective hip arthroplasty. METHODS: Twenty four fasting ASA 1-3 patients were randomly assigned, in a double blind manner, to receive intrathecal hyperbaric bupivacaine (17.5 mg), either alone (group 1), or followed by intrathecal morphine (0.6 mg) (group 2). Gastric emptying was measured (using an acetaminophen absorption technique), twice in each patient; preoperatively, and approximately one hour postoperatively. Gastric emptying parameters are: AUC (area under the plasma acetaminophen concentration time curve), maximum plasma acetaminophen concentration (Cmax), and time to Cmax (tCmax), analyzed using paired Student\\'s t tests. RESULTS: Gastric emptying rates were reduced in both group 1 (AUC = 14.98 (3.8) and 11.05 (4.6) pre- and postoperatively, respectively) and group 2 (AUC = 13.93 (3.59) and 6.4 (3.42) pre- and postoperatively, respectively); the magnitude of the reduction was greater in group 2 [AUC (P = 0.04), Cmax (P = 0.05), tCmax (P = 0.13)]. CONCLUSION: The combination of intrathecal morphine (0.6 mg) and intrathecal bupivacaine (17.5 mg) delays gastric emptying postoperatively.

Background: Police Stress Questionnaire (PSQ) was developed to measure police-specific stressors. The present study was the first to have translated the PSQ to Malay. This study aims to test the reliability, construct validity, and component structure of the Malay-version PSQ. Methods: A set of survey consisted of the Malay-version PSQ, General Health Questionnaire (GHQ-12), Job Content Questionnaire (JCQ), Global Stress Questionnaire (GSQ) and General Self-rated Health (GSRH) were distributed to 300 traffic police officers in Kuala Lumpur and all traffic police officers in a few districts of Pahang and Negeri Sembilan. Results: The response rate was 65.5% (N = 262). The reported Cronbach’s alpha coefficient was 0.93 for Operational PSQ (PSQ-Op) and 0.94 for Organisational PSQ (PSQ-Org). Findings indicated that the PSQ had positive construct validity with the GSRH, GSQ, and GHQ. After excluding four factors related to lifestyles, all police-specific stressors were highly loaded (0.50) in one component. Conclusion: It is confirmed that the Malay-version PSQ, excluding the four factors related to lifestyle, was uni-dimensional, reliable, and a valid questionnaire. This study proffers a potentially better instrument for assessing the stressors among Malaysian police. PMID:25977621

Uplifting Fear Appeals: Considering the Role of Hope in Fear-Based Persuasive Messages.

Nabi, Robin L; Myrick, Jessica Gall

2018-01-09

Fear appeal research has focused, understandably, on fear as the primary emotion motivating attitude and behavior change. However, while the threat component of fear appeals associates with fear responses, a fear appeals' efficacy component likely associates with a different emotional experience: hope. Drawing from appraisal theories of emotion in particular, this article theorizes about the role of hope in fear appeals, testing hypotheses with two existing data sets collected within the context of sun safety messages. In both studies, significant interactions between hope and self-efficacy emerged to predict behavioral intentions. Notable main effects for hope also emerged, though with less consistency. Further, these effects persisted despite controlling for the four cognitions typically considered central to fear appeal effectiveness. These results, consistent across two samples, support the claim that feelings of hope in response to fear appeals contribute to their persuasive success. Implications for developing a recursive model of fear appeal processing are discussed.

Data were collected through questionnaires and analyzed using the Likert model of multiple regression techniques. Results of hypothesis testing showed R = 0.619; F = 44.422; and p = 0.000 (p <0.05 showed that the quality of services and satisfaction of the people together influenced the image of the police. The coefficient of determination explains that the simultaneous quality of services and satisfaction of the people were able to contribute effectively to the image of the police amounted to 38.3%. The results of partial analysis shows that the relationship between service quality and image of the police has a value of p = 0.000 (p <5%, and r = 0.361, which means the quality of service to the image of the police institution is low. Partial assay analysis results between people's satisfaction with the image of the police obtained value of p = 0.000 (p <0.05; r = 0.322, which means people's satisfaction with the image of the police institutions have a significant positive correlation with the level of relationships is low

Superior learning for fear-relevant stimuli is typically indicated in the laboratory by faster acquisition of fear responses, greater learned fear, and enhanced resistance to extinction. Three experiments investigated the speed, magnitude, and robustness of UK children's (6-10 years; N = 290; 122 boys, 168 girls) vicariously learned fear responses for three types of stimuli. In two experiments, children were presented with pictures of novel animals (Australian marsupials) and flowers (fear-irrelevant stimuli) alone (control) or together with faces expressing fear or happiness. To determine learning speed the number of stimulus-face pairings seen by children was varied (1, 10, or 30 trials). Robustness of learning was examined via repeated extinction procedures over 3 weeks. A third experiment compared the magnitude and robustness of vicarious fear learning for snakes and marsupials. Significant increases in fear responses were found for snakes, marsupials and flowers. There was no indication that vicarious learning for marsupials was faster than for flowers. Moreover, vicariously learned fear was neither greater nor more robust for snakes compared to marsupials, or for marsupials compared to flowers. These findings suggest that for this age group stimulus fear relevance may have little influence on vicarious fear learning. Copyright © 2017 Elsevier Ltd. All rights reserved.

2011-04-01

The aim of the study was to explore the association between the severity of psychosomatic symptoms and perceived work stress among male police officers in southern Taiwan. By stratified random sampling, a total of 698 male police officers were recruited into this study (the response rate was 73.4%; 512 of 698). A structured self-administered questionnaire on demographic and working characteristics, the severity of psychosomatic symptoms, perceived work stress, and social support was used to collect data anonymously. The results of multiple regression analysis revealed that (1) the police officers who perceived high-work stress reported more severe psychosomatic symptoms than those who perceived low-work stress; and (2) perceived social support had a moderating effect on the association between severity of psychosomatic symptoms and perceived work stress. Perceived work stress is an indicator of psychosomatic symptoms in police officers. Strategies for reducing psychosomatic symptoms of police officers include police administrators taking into account the level of work stress as well as more attention being paid to the resources of social support.

Serotonergic Modulation of Conditioned Fear

Judith R. Homberg

2012-01-01

Full Text Available Conditioned fear plays a key role in anxiety disorders as well as depression and other neuropsychiatric conditions. Understanding how neuromodulators drive the associated learning and memory processes, including memory consolidation, retrieval/expression, and extinction (recall, is essential in the understanding of (individual differences in vulnerability to these disorders and their treatment. The human and rodent studies I review here together reveal, amongst others, that acute selective serotonin reuptake inhibitor (SSRI treatment facilitates fear conditioning, reduces contextual fear, and increases cued fear, chronic SSRI treatment reduces both contextual and cued fear, 5-HT1A receptors inhibit the acquisition and expression of contextual fear, 5-HT2A receptors facilitates the consolidation of cued and contextual fear, inactivation of 5-HT2C receptors facilitate the retrieval of cued fear memory, the 5-HT3 receptor mediates contextual fear, genetically induced increases in serotonin levels are associated with increased fear conditioning, impaired cued fear extinction, or impaired extinction recall, and that genetically induced 5-HT depletion increases fear conditioning and contextual fear. Several explanations are presented to reconcile seemingly paradoxical relationships between serotonin levels and conditioned fear.

Arresting HIV: Fostering Partnerships between Sex Workers and Police to Reduce HIV Risk and Promote Professionalization within Policing Institutions: A Realist Review.

Science.gov (United States)

Tenni, Brigitte; Carpenter, Jenae; Thomson, Nicholas

2015-01-01

In many countries around the world sex work is criminalised and its regulatory control is therefore often in the hands of the police. In addition to the impact of this criminalised legal environment, much literature describes the negative impact that certain police practices can have on the ability of sex workers and the programs that work with sex workers to access essential HIV prevention, treatment, care and support services. This situation has resulted in persistent concentrated HIV epidemics among sex workers in many countries of the world. The need for multi-sector partnerships between police and HIV programs is increasingly recognised in various UN declarations and resolutions yet descriptions of the process or key ingredients required to actually establish and sustain these necessary partnerships between police and sex workers [or the programs that provide essential services to sex workers] are sparse. The paper seeks to establish key considerations and critical processes that are required to foster partnerships that if further investigated and scaled up, could result in an enhanced enabling environment for the provision of essential HIV services for sex workers around the globe. This paper is based on a realist review that investigated isolated examples of partnership formation between law enforcement and HIV programs working with sex workers. This methodology research is designed to work with complex social interventions and is based on the emerging 'realist' approach to evaluation. A realist review methodology was chosen given the paucity of relevant literature in this vein and the authors' familiarity with the grey literature and relationships with experts who work in this sphere. The review found that political and police leadership, civil society strengthening and police reform in relation to HIV, are critical factors and key ingredients in changing the enabling environment in which sex work takes place to ensure that HIV prevention, individual and

Because various mastication-related factors influence gastric activity, the functional relationship between mastication and gastric function has not been fully elucidated. To investigate the influence of mastication on gastric emptying and motility, we conducted a randomized trial to compare the effects of mastication on gastric emptying and gastric myoelectrical activity under conditions that excluded the influences of food comminution, taste, and olfaction. A (13)C-acetate breath test with electrogastrography and electrocardiography was performed in 14 healthy men who ingested a test meal with or without chewing gum. Autonomic nerve activity was evaluated by fluctuation analysis of heart rate. Gastric emptying was significantly delayed in the 'ingestion with mastication' group. Gastric myoelectrical activity was significantly suppressed during mastication and increased gradually in the post-mastication phase. A decrease in the high-frequency power of heart rate variability was observed coincidentally with gastric myoelectrical activity suppression. These findings suggest that initial gastric emptying is suppressed by mastication, and that the suppression is caused by mastication-induced inhibition of gastric activity (UMIN Clinical Trial Registration no. UMIN000005351).

Policing the Void: Recreation, Social Inclusion and the Baltimore Police Athletic League

2017-06-01

Full Text Available In this article, we explore the relationship between public recreation policy and planning and the transformation of urban governance in the context of the Police Athletic League centers in Baltimore, Maryland. In light of contemporary discussions of the role of youth programs for sport and physical activity within post-industrial cities, the origination, development, and eventual demise of Baltimore’s network of Police Activity League centers is an instructive, if disheartening, saga. It illustrates the social and political rationales mobilized in justifying recreation policy and programming, the framing of sport and physical activity as preventative measures towards crime and juvenile delinquency, and the precarity of such initiatives given the efficiency-driven orthodoxies of neoliberal urban entrepreneurialism (Harvey, 1989. This analysis emphasizes how the PAL centers were designed to ‘fill the void’ left by a declining system of public recreation, thereby providing an example of a recreation program as part of the “social problems industry” (Pitter & Andrews 1997.

Mainstreaming gender in the police: the Maharashtra experience.

Chakravarty, S

1998-11-01

This study reviewed the history of sex segregation in the police forces of Maharashtra state, India, and policy interventions since 1994 to reverse the trends; it also describes the process of improving gender equity in the policy department as part of a gender aim to control violence against women. Police jobs are allocated based on gender. Passage of the 1975 Sex Discrimination Act was not implemented fully within police departments. In fact, the Police Force actively worked to keep itself outside the purview of the Act. Supervisors maintained the attitude that women were unsuitable for police work. Women were suspected of lacking in career commitments and were limited to only a small number within the force. These attitudes restricted women's entry, deployment, and promotions. The Government of Maharashtra has been pressured by district level women's groups to secure women's rights and to change the social environment that supports violence against women. The efforts uncovered violence unreported due to social pressure. It was thought that women's greater presence in policy departments would encourage women to report domestic crimes. The policemen disliked the interference of women. Since women were recruited for specific duties, the result was low self-esteem, frustration due to lack of promotions, sexual harassment, ostracism, and reduced job expectations. In 1993, officers received gender-sensitizing training. The training at the Institute of Development Studies at the University of Sussex focused on rules, practices, access to resources, and formal and informal inclusions and exclusions.

In absolute terms, stores provided the majority of empty calorie intake (436 kcal). The top contributors of added sugar and solid fat from each location were similar: sugar-sweetened beverages, grain desserts, and high-fat milk∗ from stores; high-fat milk, grain desserts, and pizza from schools; and sugar-sweetened beverages, dairy desserts, french fries, and pizza from fast-food restaurants. Schools contributed about 20% of children's intake of high-fat milk and pizza. These findings support the need for continued efforts to reduce empty calorie intake among US children aimed not just at fast-food restaurants, but also at stores and schools. The importance of reformed school nutrition standards was suggested, as prior to implementation of these changes, schools resembled fast-food restaurants in their contributions to empty calorie intake.

Electrogastrography allows to determinate the dominant frequency of gastric E.C.A. (electrical control activity). The aim was to investigate the gastric E.C.A. in a population of patients suffering from non-organic dispepsia (N.O.D.). Eighteen controls (9 males, 9 females, mean age 46.4 years old, SEM 3.72, range 24-72) and 52 dyspeptic patients (18 males, 34 females, mean age 54.19 years old, SEM 2.38, range 17-86) were studied. Two skin surface electrodes Ag-2ClAg were placed on epigastric area following a probabilistic antral axe. Reference electrode was placed on the right quadrant skin. In 5 patients, recordings with needle and cutaneous electrode were compared. Analogic waves were filtered, digitalized and processed. Signals were analyzed using F.F.T. (Fast Fourier Transformated) Only the predominant frequency in each block was considered, and percentage of total abnormalities on total recording time lesser than 2 c.p.m. or more than 4 c.p.m. was accepted. Recording were taken in fast time during 30 minutes, and 30 minutes after a meal containing 230 Cal. Running spectral analysis with F.F.T. In 43 non-selected patients the gastric emptying time of a mixed meal marked with 99 Tc in the solid phase was studied. 60.45% showed delayed gastric emptying. Mean of fast E.C.A. was 2.99 c.p.m. in controls, Vs 3.34 c.p.m. in dispeptic patients (p > 0.001). In the post-prandial period, mean of E.C.A. was 3.53 c.p.m. in N.O.D., and these differences were not significatives ("t", NS). 22% of controls showed isolated periods of tachygastria, but never more than 8% of the total recording time. It was seen seven six and forty five percent of arrhythmias were observed (71.15% tachygastria, 4.76% bradygastria, and 19.23% mixed) during post prandial recording in N.O.D. 48% of tachygastrias were between the range 30-60% of the time recording. Ninety six and one percent of patients with abnormal gastric emptying had gastric arrhythmias (0.05 > p > 0.02) Vs 50% in patients with

Bounded authority: Expanding "appropriate" police behavior beyond procedural justice.

2018-06-01

This paper expands previous conceptualizations of appropriate police behavior beyond procedural justice. The focus of the current study is on the notion of bounded authority-that is, acting within the limits of one's rightful authority. According to work on legal socialization, U.S. citizens come to acquire three dimensions of values that determine how authorities ought to behave: (a) neutral, consistent, and transparent decision-making; (b) interpersonal treatment that conveys respect, dignity, and concern; and (c) respecting the limits of one's rightful power. Using survey data from a nationally representative sample of U.S. adults, we show that concerns over bounded authority, respectful treatment, and neutral decision-making combine to form a strong predictor of police and legal legitimacy. We also find that legal legitimacy is associated with greater compliance behavior, controlling for personal morality and perceived likelihood of sanctions. We discuss the implications of a boundary perspective with respect to ongoing debates over the appropriate scope of police power and the utility of concentrated police activities. We also highlight the need for further research specifically focused on the psychological mechanisms underlying the formation of boundaries and why they shape the legitimacy of the police and law.

How to improve interactions between police and the mentally ill

Directory of Open Access Journals (Sweden)

Yasmeen eKrameddine

2015-01-01

Full Text Available There have been repeated instances of police forces having violent, sometimes fatal, interactions with individuals with mental illness. Police forces are frequently first responders to those with mental illness. Despite this, training police in how to best interact with individuals who have a mental illness has been poorly studied. The present article reviews the literature examining mental illness training programs delivered to law enforcement officers. Some of the key findings are the benefits of training utilizing realistic hands-on scenarios, which focus primarily on verbal and non-verbal communication, increasing empathy, and de-escalation strategies. Current issues in training police officers are firstly the tendency for organizations to provide training without proper outcome measures of effectiveness, secondly the focus of training is on changing attitudes although there is little evidence to demonstrate this relates to behavioural change, and thirdly the belief that a mental health training program given on a single occasion is sufficient to improve interactions over the longer-term. Future police training needs to address these issues.

Delayed gastric emptying is one of the reasons why functional dyspepsia (FD) occurs. The 13C-acetate breath test is widely used to evaluate gastric emptying. Nevertheless, the standard value of 13C-acetate breath test has not taken into account the gender difference of gastric emptying among healthy individuals. The main aim of this study was to readjust the standard value of 13C-acetate breath test in the light of gender differences. In addition, we clarified the prevalence and clinical characteristics of delayed gastric emptying in patients with FD using the modified standard values of 13C-acetate breath test. Fifty-two healthy individuals and 126 patients with patients with FD were enrolled. Gastric emptying was evaluated by the 13C-acetate breath test. The cut-off points of Tmax for the diagnosis of delayed gastric emptying were determined on the basis of results from healthy individuals making a distinction of genders. Gastroesophageal reflux symptoms, dyspeptic symptoms, scores of anxiety and depression, age, body mass index (BMI), smoking and alcohol consumption were compared between the delayed gastric emptying group and the non-delayed gastric emptying group. Since gastric emptying was delayed in healthy women compared with that in healthy men (Tmax, 53.6 ± 19.3 vs. 42.7 ± 16.9 min, p = 0.04), we set the cut-off points of Tmax at 60 min in men and at 75 min in women. In patients with FD, the prevalence of delayed gastric emptying was not different between men and women with the modified standard values of 13C-acetate breath test. (31.0 vs. 27.4%, p = 0.68). BMI was lower in the delayed gastric emptying group than in the non-delayed group among the male patients. Reflux symptoms were more severe in delayed gastric emptying group than in the non-delayed group among the female patients. The standard values of 13C-acetate breath test should be modified bearing the gender difference in mind. It provides us more appropriate information to understand the

Individual differences in fear generalisation have been proposed to play a role in the aetiology and/or maintenance of anxiety disorders, but few data are available to directly support that claim. The research that is available has focused mostly on generalisation of peripheral and central physiological fear responses. Far less is known about the generalisation of avoidance, the behavioural component of fear. In two experiments, we evaluated how neuroticism, a known vulnerability factor for anxiety, modulates an array of fear responses, including avoidance tendencies, towards generalisation stimuli (GS). Participants underwent differential fear conditioning, in which one conditioned stimulus (CS+) was repeatedly paired with an aversive outcome (shock; unconditioned stimulus, US), whereas another was not (CS-). Fear generalisation was observed across measures in Experiment 1 (US expectancy and evaluative ratings) and Experiment 2 (US expectancy, evaluative ratings, skin conductance, startle responses, safety behaviours), with overall highest responding to the CS+, lowest to the CS- and intermediate responding to the GSs. Neuroticism had very little impact on fear generalisation (but did affect GS recognition rates in Experiment 1), in line with the idea that fear generalisation is largely an adaptive process.

2005-01-01

Intragastric balloons have been proposed to induce weight loss in obese subjects. The consequences of the balloon on gastric physiology remain poorly studied. We studied the influence of an intragastric balloon on gastric emptying in obese patients. 12 patients were included in the study, with BMI (mean +/- SD) of 38.51 +/- 4.32 kg/m2. The balloon was inserted under light anaesthesia and endoscopic control, inflated with 700 ml saline, and removed 6 months later. Body weight and gastric emptying (T1/2 and T lag) using 13C-octanoic acid breath test were monitored before balloon placement, during its permanence and 2 months after removal. Mean weight loss was: 6.2 +/- 2.3 kg after one month; 12.4 +/- 5.8 kg after 3 months; 14.4 +/- 6.6 kg after 6 months and 10.1 +/- 4.3 kg two months after BIB removal. Gastric emptying rates were significantly decreased in the first periods with balloon in place, and returned to pre-implantation values after balloon removal. T1/2 was: 87 +/- 32 min before BIB positioning, 181 +/- 91 min after 1 month, 145 +/- 99 min after 3 months, 104 +/- 50 min after 6 months and 90 +/- 43 min 2 months after removal. T lag was 36 +/- 18 min before BIB positioning, 102 +/- 82 min after 1 month, 77 +/- 53 min after 3 months, 59 +/- 28 min after 6 months and 40 +/- 21 min. 2 months after removal. BIB in obese patients seems to be a good help in following the hypo caloric diet, especially during the first three months when the gastric emptying is slower and the sense of repletion is higher. After this period gastric emptying starts to return to normal and the stomach adapts to BIB loosing efficacy in weight loss.

Post-Soviet emptiness (Vladimir Makanin and Viktor Pelevin

Directory of Open Access Journals (Sweden)

Hans Günther

2013-01-01

Full Text Available Emptiness is a key word in several post-Soviet Russian novels of the late 1990s. One can find it as well in Vladimir Makanin's “Underground” as in two novels written by Viktor Pelevin, “Generation ‘P’” and “Chapaev and Emptiness”. After the fall of Soviet power Pelevin's cynical hero from “Generation ‘P’” changes from literature into advertising business, and in his novel “Chapaev and Emptiness” the legendary Soviet Civil War hero Chapaev transforms into a preacher of quasi-Buddhist nothingness. Makanin's hero, the writer Petrovich, renounces of his profession in order to work as a watchman in shelters for the homeless. His self-abasement is in accordance with the tradition of kenoticism (derived from the Greek word kenós = empty which played an important part in the history of Russian religious and cultural life. Criticizing the hypermoralism of classical Russian literature Makanin outlines a new image of the writer which is opposed to the Russian literary myth but still propagates moral and religious values. Pelevin's novels which reflect the relativism of postmodern poetics focus on another issue – the blurring of the difference between reality and illusion. In “Generation ‘P’”, mass media and advertising produce deceitful simulacra of reality and in “Chapaev and Emptiness” the deconstruction of Soviet mythology assumes the shape of a nightmare. Unsurprisingly, among the imagery of emptiness Malevich's famous “Black Square” including its numerous equivalents as black holes or all sorts of empty spaces is rather frequent in the three novels. Emptiness may be considered to be a characteristic trait of the atmosphere of the 1990s when Russians felt to live in a cultural vacuum somewhere between state economy and unbridled capitalism, between Soviet order and “post-slave” (Makanin chaos.

Empty 4f states in TmS

The reflectivity of TmS single crystals has been measured between 2 meV and 12 eV at room temperature and at 6 K. Besides 3p 6 -5d interband transitions a plasma edge due to free carriers is observed. In the middle infrared (near 50 meV) two sharp lines are found which are interpreted as transitions from the Fermi level into empty crystal field split 4f 13 states. A Bremsstrahlen isochromat spectroscopy (BIS) measurement supports the assumption that the empty 4f 13 state is close to the Fermi energy. (orig.)

Balancing Trust and Anxiety in a Culture of Fear

Directory of Open Access Journals (Sweden)

Jayde Cahir

2013-04-01

Full Text Available To date, there is no empirical research on the risk perceptions of Sydneysiders following the Cronulla riots nor are there any connections made between risk perceptions and ontological security in the mobile communication literature. This article addresses this gap by exploring the risk perceptions of individuals in the wake of these riots, specifically, their reactions to the new surveillance measures and policing of text messaging. This qualitative study uses empirical data collected from 30 one-on-one interviews conducted 12 to 16 months after the riots. To provide a theoretical framework for these risk perceptions Anthony Giddens’ notion of ontological security, the inner balance between trust and anxiety is used. The data analysis shows that while individuals risk perceptions are complex and contradictory, they use a range of methods to create a balance between trust and anxiety. This article argues that to manage fear in a present or perceived threat, individuals are disposed to mediate any actual or perceived risks by bracketing out anxieties to manage their everyday lives.

Bran was labelled with sup(99m)Tc-pertechnetate, ingested as part of a normal meal and used to measure gastric emptying in 15 normal subjects and in 15 patients with ulcerative colitis. There was no significant difference between the gastric emptying curves of the normal subjects and the patients, suggesting that rapid gastric emptying does not contribute to diarrhoea in ulcerative colitis.

1991-04-01

In 87 randomly selected diabetic patients (67 type 1, 20 type 2) and 25 control subjects, gastric emptying of digestible solid and liquid meals and oesophageal transit of a solid bolus were measured with scintigraphic techniques. Gastrointestinal symptoms, autonomic nerve function and glycaemic control were evaluated in the diabetic patients. Gastric emptying and oesophageal transit were slower (P<0.001) in the diabetic patients compared with the control subjects, and both were delayed in about 40% of them. There was a relatively weak (r=0.32; P<0.01) relationship between solid and liquid gastric emptying, and no significant correlation (r=0.11, NS) between oesophageal transit and gastric emptying of the solid meal. Scores for upper gastrointestinal symptoms and autonomic nerve function correlated weakly (r=0.21; P<0.05) with both oesophageal transit and gastric emptying. Gastric emptying of the liquid meal was slower (P<0.05) in patients with blood glucose concentrations >15 mmol/l. These results indicate that gastric emptying in patients with diabetes mellitus should be assessed by liquid as well as by solid test meals and that oesophageal transit should not be used as a predictor of generalised diabetic gastroenteropathy.

Gastric emptying of the fed guinea-pig was measured using a non-invasive X-ray fluoroscopic technique to determine passage from the stomach of polystyrene-coated barium sulphate spheroids. Peripherally administered metoclopramide (0.1-10 mg/kg i.p.), clebopride (1-10 mg/kg i.p.), (-)-sulpiride (40 mg/kg i.p.), haloperidol (1 mg/kg i.p.) and domperidone (1-10 mg/kg i.p.) failed to modify gastric emptying. Stress inhibited emptying, and this was considered to explain the effects of eserine and high dose metoclopramide. Gastric emptying was decreased by peripherally administered atropine (0.5 mg/kg i.p.) and apomorphine (0.1-0.5 mg/kg s.c.); the apomorphine response was antagonised by pretreatment with haloperidol, domperidone, (-)-sulpiride, metoclopramide and clebopride but not by prazosin + propranolol. Gastric emptying was facilitated by intracerebroventricular (i.c.v.) administrations of metoclopramide and clebopride (40, 100 and 200 micrograms) but not by i.c.v. domperidone, haloperidol, fluphenazine or (-)-sulpiride (100, 200 micrograms) and was inhibited by i.c.v. apomorphine (100, 200 micrograms); the response to i.c.v. apomorphine was antagonised by i.c.v. pretreatments with haloperidol, domperidone, (-)-sulpiride, metoclopramide and clebopride (40-50 micrograms). Facilitation of emptying by i.c.v. metoclopramide was prevented by peripheral pretreatment with atropine (0.5 mg/kg i.p.). It is concluded that the actions of apomorphine and metoclopramide/clebopride to respectively inhibit and facilitate gastric emptying may be mediated, at least in part, via central mechanisms. Whilst apomorphine's action may be mediated via dopamine receptor mechanisms, metoclopramide and clebopride act at additional unspecified sites, metoclopramide's action being expressed via cholinergic mechanisms.

Gastric emptying of liquids in rats dehydrated by water deprivation

Full Text Available The gastric emptying of liquids was investigated in male Wistar rats (8 to 10 weeks old, 210-300 g dehydrated by water deprivation. In this model of dehydration, weight loss, hematocrit and plasma density were significantly higher in the dehydrated animals than in the control groups after 48 and 72 h of water deprivation (P<0.05. Three test meals (saline (N = 10, water (N = 10 and a WHO rehydrating solution containing in one liter 90 mEq sodium, 20 mEq potassium, 80 mEq chloride and 30 mEq citrate (N = 10 were used to study gastric emptying following water deprivation for 24, 48 and 72 h. After 72 h, gastric emptying of the water (39.4% retention and rehydrating solution (49.2% retention test meals was significantly retarded compared to the corresponding control groups (P<0.05, Mann-Whitney test. The 72-h period of deprivation was used to study the recovery from dehydration, and water was supplied for 60 or 120 min after 67 h of deprivation. Body weight loss, hematocrit and plasma density tended to return to normal when water was offered for 120 min. In the animals supplied with water for 60 min, there was a recovery in the gastric emptying of water while the gastric emptying of the rehydrating solution was still retarded (53.1% retention; P<0.02, Kruskal-Wallis test. In the group supplied with water for 120 min, the gastric emptying of the rehydrating (51.7% retention and gluco-saline (46.0% retention solutions tended to be retarded (P = 0.04, Kruskal-Wallis test. In this model of dehydration caused by water deprivation, with little alteration in the body electrolyte content, gastric emptying of the rehydrating solution was retarded after rehydration with water. We conclude that the mechanisms whereby receptors in the duodenal mucosa can modify gastric motility are altered during dehydration caused by water deprivation

Opioid-induced delay in gastric emptying: a peripheral mechanism in humans.

LENUS (Irish Health Repository)

Murphy, D B

2012-02-03

BACKGROUND: Opioids delay gastric emptying, which in turn may increase the risk of vomiting and pulmonary aspiration. Naloxone reverses this opiate action on gastric emptying, but it is not known whether this effect in humans is mediated by central or peripheral opiate antagonism. The importance of peripheral opioid receptor antagonism in modulating opioid-induced delay in gastric emptying was evaluated using methylnaltrexone, a quaternary derivative of the opiate antagonist naltrexone, which does not cross the blood-brain barrier. METHODS: In a randomized, double-blind, crossover placebo-controlled study, 11 healthy volunteers were given either placebo (saline), 0.09 mg\\/kg morphine, or 0.09 mg\\/kg morphine plus 0.3 mg\\/kg methylnaltrexone on three separate occasions before ingesting 500 ml deionized water. The rate of gastric emptying was measured by two methods: a noninvasive epigastric bioimpedance technique and the acetaminophen absorption test. RESULTS: The epigastric bioimpedance technique was sufficiently sensitive to detect opioid-induced changes in the rate of gastric emptying. The mean +\\/- SD time taken for the gastric volume to decrease to 50% (t0.5) after placebo was 5.5 +\\/- 2.1 min. Morphine prolonged gastric emptying to (t0.5) of 21 +\\/- 9.0 min (P < 0.03). Methylnaltrexone given concomitantly with morphine reversed the morphine-induced delay in gastric emptying to a t0.5 of 7.4 +\\/- 3.0 (P < 0.04). Maximum concentrations and area under the concentration curve from 0 to 90 min of serum acetaminophen concentrations after morphine were significantly different from placebo and morphine administered concomitantly with methylnaltrexone (P < 0.05). No difference in maximum concentration or area under the concentration curve from 0 to 90 min was noted between placebo and methylnaltrexone coadministered with morphine. CONCLUSIONS: The attenuation of morphine-induced delay in gastric emptying by methylnaltrexone suggests that the opioid effect is

To investigate whether the sulfamethizole absorption test can be applied for the assessment of gastric emptying, the authors measured comparatively plasma sulfamethizole concentration and gastric emptying determined by scintigraphy in 15 subjects. After the ingestion of a solid-liquid meal that contained sulfamethizole and radioisotope (technitium-99m-labelled diethylenetraminepentaacetic acid), the plasma sulfamethizole concentrations were measured every 15 to 60 min up to 180 min. The initial emptying time and the exponential curve in the cumulative reduction of radioactivity were used as indicators of gastric emptying. The initial emptying time was significantly correlated with the sulfamethizole concentration at 15 min after ingestion. A close correlation was observed between the rate of decrease in radioactivity and sulfamethizole concentration at 60 min after ingestion. The sulfamethizole absorption test can be used for the evaluation of gastric motility. Two points of measurement, 15 and 60 min after ingestion, are sufficient to demonstrate the initial and subsequent gastric emptying. 21 refs., 4 figs., 3 tabs.

Radionuclide gastric emptying studies are performed as a matter of clinical routine. Our aim was to evaluate the inter- and intra-individual variability and the reproducibility of gastric emptying studies in healthy young male volunteers using a single solid-phase, standard meal. The meal consisted of a pancake (500 KJ) tagged with 99m Tc-labeled sulfur colloid and no additional liquid. Continuous acquisitions of gastric activity in anterior projection were taken during 90 min, starting from the onset of the meal. Gastric emptying was evaluated three times in a 3-week period. Five different parameters were evaluated. Our results show that there is important inter- and intra-individual variability in normal volunteers. In spite of this variability, no significant difference between the different series of gastric emptying studies was observed. (orig.)

Equal pain – Unequal fear response: Enhanced susceptibility of tooth pain to fear conditioning

Michael Lukas Meier

2014-07-01

Full Text Available Experimental fear conditioning in humans is widely used as a model to investigate the neural basis of fear learning and to unravel the pathogenesis of anxiety disorders. It has been observed that fear conditioning depends on stimulus salience and subject vulnerability to fear. It is further known that the prevalence of dental-related fear and phobia is exceedingly high in the population. Dental phobia is unique as no other body part is associated with a specific phobia. Therefore, we hypothesized that painful dental stimuli exhibit an enhanced susceptibility to fear conditioning when comparing to equal perceived stimuli applied to other body sites. Differential susceptibility to pain-related fear was investigated by analyzing responses to an unconditioned stimulus (UCS applied to the right maxillary canine (UCS-c versus the right tibia (UCS-t. For fear conditioning, UCS-c and USC-t consisted of painful electric stimuli, carefully matched at both application sites for equal intensity and quality perception. UCSs were paired to simple geometrical forms which served as conditioned stimuli (CS+. Unpaired CS+ were presented for eliciting and analyzing conditioned fear responses. Outcome parameter were 1 skin conductance changes and 2 time-dependent brain activity (BOLD responses in fear-related brain regions such as the amygdala, anterior cingulate cortex, insula, thalamus, orbitofrontal cortex and medial prefrontal cortex.A preferential susceptibility of dental pain to fear conditioning was observed, reflected by heightened skin conductance responses and enhanced time-dependent brain activity (BOLD responses in the fear network. For the first time, this study demonstrates fear-related neurobiological mechanisms that point towards a superior conditionability of tooth pain. Beside traumatic dental experiences our results offer novel evidence that might explain the high prevalence of dental-related fears in the population.

Full Text Available In early 2012, 76 heavily armed police conducted a raid on a house in Auckland, New Zealand. The targets were Kim Dotcom, a German national with a NZ residency visa, and several colleagues affiliated with Megaupload, an online subscription-based peer-to-peer (P2P file sharing facility. The alleged offences involved facilitating unlawful file sharing and United States federal criminal copyright violations. Following the raid, several court cases provide valuable insights into emerging ‘global policing’ practices (Bowling and Sheptycki 2012 based on communications between sovereign enforcement agencies.  This article uses these cases to explore the growth of ‘extraterritorial’ police powers that operate ‘across borders’ (Nadelmann 1993 as part of several broader transformations of global policing in the digital age.

Simultaneous measurements of the gastric emptying rate of the solid and liquid phase of a dual-isotope-labeled test meal were made using a gamma camera and a simple scintillation detector, similar to that used in a hand-held probe. A simple scanning apparatus, similar to that used in a hand-held scintillation probe, was compared with simultaneous measurements made by a gamma camera in 16 healthy males. A dual-labeled test meal was utilized to measure liquid and solid emptying simultaneously. Anterior and posterior scans were taken at intervals up to 120 min using both a gamma camera and the scintillation probe. Good relative agreement between the methods was obtained both for solid-phase (correlation range 0.92-0.99, mean 0.97) and for liquid-phase data (correlation range 0.93-0.99, mean 0.97). For solid emptying data regression line slopes varied from 0.75 to 1.03 (mean 0.84). Liquid emptying data indicated that slopes ranged from 0.71 to 1.06 (mean 0.87). These results suggested that an estimate of the gamma measurement could be obtained by multiplying the scintillation measurement by a factor of 0.84 for the solid phase and 0.87 for the liquid phase. Correlation between repeat studies was 0.97 and 0.96 for solids and liquids, respectively. The application of a hand-held probe technique provides a noninvasive and inexpensive method for accurately assessing solid- and liquid-phase gastric emptying from the human stomach that correlates well with the use of a gamma camera, within the range of gastric emptying rate in the normal individuals in this study.

DESIGNING DAILY PATROL ROUTES FOR POLICING BASED ON ANT COLONY ALGORITHM

H. Chen

2015-07-01

Full Text Available In this paper, we address the problem of planning police patrol routes to regularly cover street segments of high crime density (hotspots with limited police forces. A good patrolling strategy is required to minimise the average time lag between two consecutive visits to hotspots, as well as coordinating multiple patrollers and imparting unpredictability in patrol routes. Previous studies have designed different police patrol strategies for routing police patrol, but these strategies have difficulty in generalising to real patrolling and meeting various requirements. In this research we develop a new police patrolling strategy based on Bayesian method and ant colony algorithm. In this strategy, virtual marker (pheromone is laid to mark the visiting history of each crime hotspot, and patrollers continuously decide which hotspot to patrol next based on pheromone level and other variables. Simulation results using real data testifies the effective, scalable, unpredictable and extensible nature of this strategy.

A new mode of fear expression: perceptual bias in height fear.

2008-04-01

Emotion and psychopathology researchers have described the fear response as consisting of four main components--subjective affect, physiology, cognition, and behavior. The current study provides evidence for an additional component in the domain of height fear (perception) and shows that it is distinct from measures of cognitive processing. Individuals High (N = 35) and Low (N = 36) in acrophobic symptoms looked over a two-story balcony ledge and estimated its vertical extent using a direct height estimation task (visual matching), and an indirect task (size estimation); the latter task seems to exhibit little influence from cognitive factors. In addition, implicit and explicit measures of cognitive processing were obtained. Results indicated that, as expected, the High Fear group showed greater relative, implicit height fear associations and explicit threat cognitions. Of primary interest, the High (compared to Low) Fear group estimated the vertical extent to be higher, and judged target sizes to be greater, even when controlling for the cognitive bias measures. These results suggest that emotional factors such as fear are related to perception. (Copyright) 2008 APA.

Boateng, Francis D

2018-02-01

While much is known about fear of crime in the West, little is known about how fearfulness of crime develops in non-Western societies, especially among university students. Representing the first attempt to empirically compare levels of fear of crime between Ghanaian and U.S. college students, this article examined students' levels of fear of crime on campus, and tested the applicability of two evolving models of fear of crime-the vulnerability and reassurance models-using comparative data. The general finding is that Ghanaian and U.S. college students differ in terms of their rates of fearfulness on campus. This significant difference adds to the already existing differences between the two countries.

This study was designed to assess the relative influence of meal weight and caloric content on gastric emptying of liquid and solid meals in man. A dual radioisotopic method which permits noninvasive and simultaneous measurement of liquid- and solid-phase emptying by external gamma camera techniques was employed. Nine healthy volunteer subjects ingested 50-, 300-, and 900-g lettuce and water meals adjusted to either 68, 208, or 633 kcal with added salad oil. The following observations were made: (1) absolute emptying rates (grams of solid food emptied from the stomach per minute) increased directly and significantly with meal weight; (2) increasing meal total caloric content significantly slowed solid food gastric emptying but did not overcome the enhancing effect of meal weight; and (3) liquid emptying rates were uninfluenced by meal total kcal amount

Full Text Available Objective to determine the reliability and objectivity of information to the population on the functioning of police in Volgograd oblast. Methods sociological absentee polling in the form of a questionnaire statistical logical documentary graphic method of systemic analysis. Results the opinions of the population on police are extremely controversial. It is connected mostly with the sources of information which mostly are not reliable and objective. The article shows that despite the growth of victimization the level of anxiety of the population about the criminal attacks is gradually reduced and the sense of security in citizens is strengthened though often due to their personal efforts to protect their life health and property. Only every fifth citizen relies on the participation of law enforcers in ensuring security and public order. The survey revealed that about half of the citizens who are potentially interested in the reaction of law enforcement officers to the crime actually agree to leave the offender unpunished due to the mistrust of the police. A third of claimants were unsatisfied with the police action on their application which does not correlate with the declared numbers. The opinion of Volgograd citizens on the frequency of bribery among police officers remains unchanged whereas other malfeasances received a significant increase. And despite this the attitude of the respondents towards the police in general has improved. Mostly it was the result of media activities that inform the public about successful police work using TV shows documentaries and feature films. The successful work of the police is also confirmed by statistic that shows the rapid decline in recorded crime. Scientific novelty for the first time on the basis of a combination of various methods the reliability and objectivity of information to the population is investigated on the police of Volgograd oblast.

Full Text Available This paper proposes an analysis of practices of police assistance to women victims of gender violence in four police stations of the State of Rio de Janeiro, two of them  specialized in assisting with this type of conflict, located in the state capital, and two others, not specialized, located in the countryside. The creation of the Specialized Police Assistance to Women in the mid 80s was the result of pressure from the feminist movement over the government in the political context of democratization of the country after the military dictatorship. We emphasize the existence, in the daily routine of the police stations, of the confrontation among different representations on the nature of this conflict, and we have tried to analyze, in a comparative way, how this fact affects the police practices observed, in order to verify if the specialized police stations present practices of conflict management which are differentiated and more suitable to the conceptions that have guided their creation as public policy of gender.

Police are exposed to a wide range of stressors and this is especially true in developing countries such as Jamaica. Exposure to psychosocial stressors and use of maladaptive coping styles can result in mental ill-health. To examine the relationship between work characteristics, coping and mental health in Jamaican police officers and to test whether work characteristics are indirectly associated with mental health outcomes through perceived job stress and job satisfaction. Police officers from the Jamaican police force completed a questionnaire using a cross-sectional design. We analysed the data using hierarchical regression. The study group consisted of 134 police officers; the response rate was 94%. Negative work characteristics, lower levels of positive work factors and work support and emotion-focused coping styles were associated with increased levels of depression (F(8, 125) = 7.465, P health outcomes was mediated by perceived stress. Job satisfaction mediated the relationship between positive work characteristics and depression. Stress management and intervention programmes should address modifiable work conditions, monitor stress levels and reduce maladaptive coping. © The Author 2016.

Full Text Available Despite Thailand's commitment to treating people who use drugs as "patients" not "criminals," Thai authorities continue to emphasize criminal law enforcement for drug control. In 2003, Thailand's drug war received international criticism due to extensive human rights violations. However, few studies have since investigated the impact of policing on drug-using populations. Therefore, we sought to examine experiences with policing among people who inject drugs (PWID in Bangkok, Thailand, between 2008 and 2012.Between July 2011 and June 2012, semi-structured, in-depth interviews were conducted with 42 community-recruited PWID participating in the Mitsampan Community Research Project in Bangkok. Interviews explored PWID's encounters with police during the past three years. Audio-recorded interviews were transcribed verbatim, and a thematic analysis was conducted to document the character of PWID's experiences with police. Respondents indicated that policing activities had noticeably intensified since rapid urine toxicology screening became available to police. Respondents reported various forms of police misconduct, including false accusations, coercion of confessions, excessive use of force, and extortion of money. However, respondents were reluctant to report misconduct to the authorities in the face of social and structural barriers to seeking justice. Respondents' strategies to avoid police impeded access to health care and facilitated transitions towards the misuse of prescribed pharmaceuticals. The study's limitations relate to the transferability of the findings, including the potential biases associated with the small convenience sample.This study suggests that policing in Bangkok has involved injustices, human rights abuses, and corruption, and policing practices in this setting appeared to have increased PWID's vulnerability to poor health through various pathways. Novel to this study are findings pertaining to the use of urine drug

To distinguish normative fears from problematic fears and phobias. We investigated 2,512 children and adolescents from a large community school-based study, the High Risk Study for Psychiatric Disorders. Parent reports of 18 fears and psychiatric diagnosis were investigated. We used two analytical approaches: confirmatory factor analysis (CFA)/item response theory (IRT) and nonparametric receiver operating characteristic (ROC) curve. According to IRT and ROC analyses, social fears are more likely to indicate problems and phobias than specific fears. Most specific fears were normative when mild; all specific fears indicate problems when pervasive. In addition, the situational fear of toilets and people who look unusual were highly indicative of specific phobia. Among social fears, those not restricted to performance and fear of writing in front of others indicate problems when mild. All social fears indicate problems and are highly indicative of social phobia when pervasive. These preliminary findings provide guidance for clinicians and researchers to determine the boundaries that separate normative fears from problem indicators in children and adolescents, and indicate a differential severity threshold for specific and social fears.

2016-04-01

Full Text Available Police safety and use of force decisions during critical incidents are an ongoing source of concern for both police practitioners and the public. Prior research in the area of police performance reveals that psychological and physiological stress responses during critical incidents can shape the outcome of the incident, either positively or negatively. The goal of this study was to test a training method to improve use of force decision making among police. This randomized controlled pilot study consisted of training officers to apply techniques to enhance psychological and physiological control during stressful critical incidents. Of a pool of 80 police officers, potential participants were invited based on equivalent age, years of experience, physiological characteristics (i.e., body mass index [BMI] and cardiovascular reactivity, and expertise. Results revealed that the intervention group displayed significantly better physiological control, situational awareness, and overall performance, and made a greater number of correct use of force decisions than officers in the control group (all ps < .01. The relevant improvements in use of force decision-making found in this pilot study indicate that this training method warrants further investigation. Improved use of force decision making directly translates into potential lifesaving decisions for police and the civilians they are working with.

Scale-space for empty catheter segmentation in PCI fluoroscopic images.

In this article, we present a method for empty guiding catheter segmentation in fluoroscopic X-ray images. The guiding catheter, being a commonly visible landmark, its segmentation is an important and a difficult brick for Percutaneous Coronary Intervention (PCI) procedure modeling. In number of clinical situations, the catheter is empty and appears as a low contrasted structure with two parallel and partially disconnected edges. To segment it, we work on the level-set scale-space of image, the min tree, to extract curve blobs. We then propose a novel structural scale-space, a hierarchy built on these curve blobs. The deep connected component, i.e. the cluster of curve blobs on this hierarchy, that maximizes the likelihood to be an empty catheter is retained as final segmentation. We evaluate the performance of the algorithm on a database of 1250 fluoroscopic images from 6 patients. As a result, we obtain very good qualitative and quantitative segmentation performance, with mean precision and recall of 80.48 and 63.04% respectively. We develop a novel structural scale-space to segment a structured object, the empty catheter, in challenging situations where the information content is very sparse in the images. Fully-automatic empty catheter segmentation in X-ray fluoroscopic images is an important and preliminary step in PCI procedure modeling, as it aids in tagging the arrival and removal location of other interventional tools.

The consumption of psychoactive substances by civil and military police of the city of Rio de Janeiro was investigated. Data was gathered from two cross-sectional studies on a questionnaire on work and health conditions given to a sample from the two corporations. The results show higher frequencies of regular consumption of tobacco (23.3% by civil police and 19.1% by military police), daily use of alcohol (12% by civil police and 11% by military police) and tranquilizers in the past year (13.3% by civil police and 10.1% by military police). The consumption of marijuana among officers was 0.1% by civil police and 1.1% by military police, and cocaine use among the military police was 1.1%. Alcohol consumption proved to be intense and causes problems at work and in the social and family relationships of these officers. The need for preventive policies for addiction and the possible underestimation of information on illicit substances is emphasized.

The present research investigated the resulting contextual fear memory and structural plasticity changes in the dorsal hippocampus (DH) following stress and fear conditioning. This combination enhanced fear retention and increased the number of total and mature dendritic spines in DH. Intra-basolateral amygdala (BLA) infusion of midazolam prior to stress prevented both the enhancement of fear retention and an increase in the density of total and mature dendritic spines in DH. These findings emphasize the role of the stress-induced attenuation of GABAergic neurotransmission in BLA in the promoting influence of stress on fear memory and on synaptic remodeling in DH. In conclusion, the structural remodeling in DH accompanied the facilitated fear memory following a combination of fear conditioning and stressful stimulation.

1994-12-01

We have developed a breath test to measure solid gastric emptying using a standardized scrambled egg test meal (250 kcal) labeled with [14C]octanoic acid or [13C]octanoic acid. In vitro incubation studies showed that octanoic acid is a reliable marker of the solid phase. The breath test was validated in 36 subjects by simultaneous radioscintigraphic and breath test measurements. Nine healthy volunteers were studied after intravenous administration of 200 mg erythromycin and peroral administration of 30 mg propantheline, respectively. Erythromycin significantly enhanced gastric emptying, while propantheline significantly reduced gastric emptying rates. We conclude that the [*C]octanoic breath test is a promising and reliable test for measuring the gastric emptying rate of solids.

Total body irradiation is followed within minutes by nausea and vomiting. In dogs, the authors found that gastric emptying was suppressed for at least 3 hours after exposure to 8 Gy Cobalt-60; in addition, pretreatment with domperidone (D) could prevent vomiting without improving gastric emptying. In the present studies, the authors used a primate model to further investigate the possibility of treating radiation induced vomiting and delayed gastric emptying. Gastric emptying was measured using either (1) radionuclide imaging after intragastric administration of chicken liver tagged in vivo with 1 mCi Tc-99m sulfur colloid and water containing 0.2 mCi In-111-DTPA; or (2) a Tc-99 m-DPTA dilution technique. Chair-adapted rhesus monkeys were studied in the basal state receiving either saline (S; 1.0 ml), D (0.1 mg/kg) or metoclopramide (M; 0.15 mg/kg). All monkeys were then exposed to total body irradiation (8 Gy, Cobalt-60) after receiving either S, D or M. Vomiting was observed in 5 of 6 monkeys receiving S or D but in only one of 5 animals pretreated with M. Gastric emptying was unaffected by any drug in the basal state (S: 5.54 +- 0.86; D: 6.21 +- 1.01; P: 6.52 +- 0.95%/min; means +- SE). After irradiation, emptying was completely abolished in animals treated with S (0.2 +- 0.2%/min) or D (0.1 +- 0.1%/min; in contrast, pretreatment with M improved gastric emptying significantly (1.81 +- 0.52%/min. Thus, gastric emptying is suppressed in monkeys who vomit after exposure to total body irradiation. In addition, vomiting is prevented and suppression of gastric emptying is improved by M, a dopamine antagonist that acts centrally but not by D, a peripherally acting dopamine antagonist

Full Text Available Objective: To distinguish normative fears from problematic fears and phobias. Methods: We investigated 2,512 children and adolescents from a large community school-based study, the High Risk Study for Psychiatric Disorders. Parent reports of 18 fears and psychiatric diagnosis were investigated. We used two analytical approaches: confirmatory factor analysis (CFA/item response theory (IRT and nonparametric receiver operating characteristic (ROC curve. Results: According to IRT and ROC analyses, social fears are more likely to indicate problems and phobias than specific fears. Most specific fears were normative when mild; all specific fears indicate problems when pervasive. In addition, the situational fear of toilets and people who look unusual were highly indicative of specific phobia. Among social fears, those not restricted to performance and fear of writing in front of others indicate problems when mild. All social fears indicate problems and are highly indicative of social phobia when pervasive. Conclusion: These preliminary findings provide guidance for clinicians and researchers to determine the boundaries that separate normative fears from problem indicators in children and adolescents, and indicate a differential severity threshold for specific and social fears.

Fear conditioning studies in adults have found that posttraumatic stress disorder (PTSD) is associated with heightened fear responses and impaired discrimination. The objective of the current study was to examine the association between PTSD symptoms and fear conditioned responses in children from a highly traumatized urban population. Children between 8 and 13 years old participated in a fear conditioning study in addition to providing information about their trauma history and PTSD symptoms. Results showed that females showed less discrimination between danger and safety signals during conditioning compared to age-matched males. In boys, intrusive symptoms were predictive of fear responses, even after controlling for trauma exposure. However, in girls, conditioned fear to the danger cue was predictive of self-blame and fear of repeated trauma. This study suggests there are early sex differences in the patterns of fear conditioning and that these sex differences may translate to differential risk for trauma-related psychopathology. © 2015 Wiley Periodicals, Inc.

1983-12-01

Gastric emptying has an important role in the pathophysiology of gastroesophageal reflux disease. The effect of metoclopramide, a gastric prokinetic agent, in gastroesophageal reflux patients with normal as well as delayed emptying was investigated. Twenty-six patients with subjective and objective evidence of gastroesophageal reflux ingested an egg salad sandwich meal labeled with /sub 99m/technetium-DTPA for a baseline study, and then again on a separate day after receiving oral metoclopramide, 10 mg, 30 min prior to the test meal. The mean percent isotope remaining in the stomach after 90 min improved significantly from 70.3 +/- 3.9% (SEM) to 55.2 +/- 4.2% after metoclopramide. Fourteen (54%) had a basal emptying in the normal range of 34-69% retention of isotope at 90 min, (means +/- 2 SD), while it was slow in 12 (46%). For those with delayed basal gastric emptying, the mean retention of 88.9 +/- 2.9% at 90 min was significantly decreased by metoclopramide to 68.6 +/- 6.1%. In those patients with a normal basal gastric emptying and a mean retention of 54.4 +/- 2.3% at 90 min, there was also significant improvement (P less than 0.025) to 43.6 +/- 3.6% after metoclopramide. These data indicate that metoclopramide increased gastric emptying in gastroesophageal reflux patients with normal as well as delayed gastric emptying. Therefore on a patient management level a trial of metoclopramide is warranted in patients with gastroesophageal reflux disease and is not limited by the gastric emptying status of the patient.

Tomkiewicz, J; Bass, K

1999-12-01

The primary purpose of this research was to examine whether fear of success and of appearing incompetent among women have changed recently. Another purpose was to examine whether such fears differed among women who hold Traditional views and those who hold Progressive views about the roles of women in the workplace. The Fear of Success Scale, the Fear of Appearing Incompetent Scale, and the Attitude Toward Women Scale were completed by 61 male and 52 female graduating seniors. Significant differences were found between the groups for scores on the Attitude Toward Women Scale, but none between the sexes for scores on the Fear of Success Scale or the Fear of Appearing Incompetent Scale. Significant differences were found, however, on the latter two scales when women were separated into Traditional and Progressive groups.

Role of the police in linking individuals experiencing mental health crises with mental health services

Science.gov (United States)

2012-01-01

Background The police are considered frontline professionals in managing individuals experiencing mental health crises. This study examines the extent to which these individuals are disconnected from mental health services, and whether the police response has an influence on re-establishing contact. Methods Police records were searched for calls regarding individuals with acute mental health needs and police handling of these calls. Mental healthcare contact data were retrieved from a Psychiatric Case Register. Results The police were called upon for mental health crisis situations 492 times within the study year, involving 336 individuals (i.e. 1.7 per 1000 inhabitants per year). Half of these individuals (N=162) were disengaged from mental health services, lacking regular care contact in the year prior to the crisis (apart from contact for crisis intervention). In the month following the crisis, 21% of those who were previously disengaged from services had regular care contact, and this was more frequent (49%) if the police had contacted the mental health services during the crisis. The influence of police referral to the services was still present the following year. However, for the majority (58%) of disengaged individuals police did not contact the mental health services at the time of crisis. Conclusions The police deal with a substantial number of individuals experiencing a mental health crisis, half of whom are out of contact with mental health services, and police play an important role in linking these individuals to services. Training police officers to recognise and handle mental health crises, and implementing practical models of cooperation between the police and mental health services in dealing with such crises may further improve police referral of individuals disengaged from mental health services.

The odds-ratio of smoking is elevated in populations with neuropsychiatric diseases, in particular in the highly prevalent diagnoses of post-traumatic stress and anxiety disorders. Yet, the association between smoking and a key dimensional phenotype of these disorders-maladaptive deficits in fear learning and fear inhibition-is unclear. We therefore investigated acquisition and memory of fear and fear inhibition in healthy smoking and non-smoking participants (N=349, 22% smokers). We employed a well validated paradigm of context-dependent fear and safety learning (day 1) including a memory retrieval on day 2. During fear learning, a geometrical shape was associated with an aversive electrical stimulation (classical fear conditioning, in danger context) and fear responses were extinguished within another context (extinction learning, in safe context). On day 2, the conditioned stimuli were presented again in both contexts, without any aversive stimulation. Autonomic physiological measurements of skin conductance responses as well as subjective evaluations of fear and expectancy of the aversive stimulation were acquired. We found that impairment of fear inhibition (extinction) in the safe context during learning (day 1) was associated with the amount of pack-years in smokers. During retrieval of fear memories (day 2), smokers showed an impairment of contextual (safety context-related) fear inhibition as compared with non-smokers. These effects were found in physiological as well as subjective measures of fear. We provide initial evidence that smokers as compared with non-smokers show an impairment of fear inhibition. We propose that smokers have a deficit in integrating contextual signs of safety, which is a hallmark of post-traumatic stress and anxiety disorders.

Standing By Police Violence: On the Constitution of the Ideal Citizen as Sousveiller

Directory of Open Access Journals (Sweden)

Ben Brucato

2016-10-01

Full Text Available Individual citizens and social movement organizations document police with video, both serendipitously and deliberately. This documentation is characterized as an intervention, one that not only promises to alter events, but to fulfill civic responsibilities. Simply, video recording police makes one an active citizen, rather than a passive bystander. For instance, at Occupy Wall Street, video recording was a primary and normalized response by protesters when police used coercive force against other protesters. Their use of video streaming apps to live-broadcast such events—while chanting “The whole world is watching!”—shows how protesters framed watching as an intercession. The National Police Monitoring and Reporting Project frames citizen documentation of police as a duty, one that produces protective power against police violence. Copwatch “know your rights” training similarly portrays spontaneous filming as an intervention in violent policing. In other cases, however, video documentation is cast as a shame-worthy denial of a citizen’s responsibility to intervene to stop the perpetration of violence. In light of its equivocal standing, the treatment of documenting violence as an intervention is in doubt.

The variety of tasks that characterize police work highlights the importance of being in good physical condition. To take a first step at standardizing the administration of a job-related test to assess a person's ability to perform the physical demands of the core tasks of police work. The principal research questions were: are test scores related to gender, age and function and are test scores related to body mass index (BMI) and the number of hours of physical exercise? Data of 6999 police officers, geographically spread over all parts of The Netherlands, who completed a physical competence test over a 1 year period were analysed. Women performed the test significantly more slowly than men. The mean test score was also related to age; the older a person the longer it took to complete the test. A higher BMI was associated with less hours of body exercise a week and a slower test performance, both in women and men. The differences in individual test scores, based on gender and age, have implications for future strategy within the police force. From a viewpoint of 'same job, same standard' one has to accept that test-score differences may lead to the exclusion of certain staff. However, from a viewpoint of 'diversity as a business issue', one may have to accept that on average, both female and older police officers are physically less tailored to their jobs than their male and younger colleagues.

Fear appeals are a polarizing issue, with proponents confident in their efficacy and opponents confident that they backfire. We present the results of a comprehensive meta-analysis investigating fear appeals’ effectiveness for influencing attitudes, intentions, and behaviors. We tested predictions from a large number of theories, the majority of which have never been tested meta-analytically until now. Studies were included if they contained a treatment group exposed to a fear appeal, a valid comparison group, a manipulation of depicted fear, a measure of attitudes, intentions, or behaviors concerning the targeted risk or recommended solution, and adequate statistics to calculate effect sizes. The meta-analysis included 127 papers (9% unpublished) yielding 248 independent samples (NTotal = 27,372) collected from diverse populations. Results showed a positive effect of fear appeals on attitudes, intentions, and behaviors, with the average effect on a composite index being random-effects d¯ = 0.29. Moderation analyses based on prominent fear appeal theories showed that the effectiveness of fear appeals increased when the message included efficacy statements, depicted high susceptibility and severity, recommended one-time only (vs. repeated) behaviors, and targeted audiences that included a larger percentage of female message recipients. Overall, we conclude that (a) fear appeals are effective at positively influencing attitude, intentions, and behaviors, (b) there are very few circumstances under which they are not effective, and (c) there are no identified circumstances under which they backfire and lead to undesirable outcomes.

Police must join the fast track to end AIDS by 2030.

Science.gov (United States)

Crofts, Nick; Patterson, David

2016-01-01

World leaders have committed to ending AIDS by 2030, but stigma and discrimination remain significant obstacles. In particular, police are critical, front-line determinants of risk for many people living with HIV (PLHIV) and members of other key affected populations (KAPs). The negative impact of adverse police behaviours and practices on HIV risk is well documented, and these risks undermine global efforts to end AIDS. Far less well documented, and less common, are attempts to ameliorate this impact by working to change police behaviours. This Special Issue seeks to help redress this imbalance by presenting a selection of original, provocative and important interventions from academics, police officers and other stakeholders concerned with documenting the potential for constructive, progressive and evidence-based approaches to the reduction of HIV risk. We recommend urgent boosting of efforts and funding to engage police in the HIV response. Among other strategies, this needs sustainable funding of programmes and their evaluation, and increased and continuing advocacy and education at all levels to match policy and law reform.

In this study, we have evaluated the effect of the caloric content of a physiological test meal on the gastric emptying kinetics of solids and liquids. 22 healthy male volunteers were studied in two groups matched for age. After an overnight fast, each volunteer underwent the same test procedure; in the first group (G I), 10 volunteers received a meal consisting of bread, 111In-DTPA water and 1 scrambled egg labeled with 99mTc-labelled sulphur colloid; in the second group (G II) 12 volunteers were given the same meal but with 2 labeled eggs in order to increase the caloric content of the solid phase meal. Simultaneous anterior and posterior images were recorded using a dual-headed gamma camera. Solid and liquid geometric mean data were analyzed to determine the lag phase, the emptying rate and the half-emptying time for both solids and liquids. Solid and liquid gastric half-emptying times were significantly prolonged in G II compared to G I volunteers. For the solid phased, the delay was accounted for by a longer lag phase and a decrease in the equilibrium emptying rate. The emptying rate of the liquid phase was significantly decreased in G II compared to G I. Within each group, no statistically significant difference was observed between solid and liquid emptying rates. We conclude that the caloric content of the solid portion of a meal not only alters the emptying of the solid phase but also affects the emptying of the liquid component of the meal.

Measurement of gastric emptying using isotopic method in diabetes, simple obesity and anorexia nervosa

Gastric emptying of technetium labeled liquid meal were studied in 46 non-insulin-dependent diabetics, 7 obese patients, 8 anorexia nervosa patients, and 21 normal subjects. All subjects underwent endoscopy and barium study, and none showed any lesion in upper gastrointestinal tract. T1/2, time at which 50% of meal remained, was used as an indicator of gastric emptying. Eight normal subjects have some epigastric discomforts, and have slightly slower gastric emptying than the remaining 13 subjects. But there was no significant difference in T1/2 between the both groups (53.2±12.8 min vs 45.1±10.9 min). Fourteen diabetics have some epigastric discomforts, and have significantly more slower gastric emptying than the remaining 32 diabetics (T1/2; 67.7±24.6 vs 50.5±17.4, p<0.02). The gastric emptying of 13 diabetics who have three major diabetic complications (retinopathy, nephropathy, and peripheral neuropathy), was significantly more slower than that of 15 diabetics without any complication (T1/2; 68.1±24.6 vs 43.5±14.8, p<0.005). The gastric emptying of simple obesity did not show a fixed pattern, but the emptying of anorexia nervosa was remarkably delayed. These findings indicate that diabetic gastroparesis is common in the presence of the three major complications, and the delayed gastric emptying is associated with post-prandial discomfort in diabetics and anorexia nervosa patients. The measurement of gastric emptying can be useful to evaluate the management and the treatment for diabetes and anorexia nervosa. (author)

Administrative processing by the police may affect the process involved in organ donation in the event of an accidental brain injury. The purpose of this study was to evaluate the knowledge and attitude of police toward brain-dead donors and organ donation. This was a descriptive research study using a 41-item questionnaire. As of July 19, 2017, 11 police stations in Seoul had collected questionnaires completed by 115 police officers. Data were analyzed using SAS (version 9.4) software. There were statistically significant differences in the scores on knowledge about brain death/donation according to religion (P = .022). Attitude was significantly positively correlated with the knowledge about brain-death organ donation (P = .029). It is necessary to understand and cooperate with the police when processing brain death organs from accidents. Education about organ donation can enhance the information and knowledge of the police and can also help to establish a positive attitude about organ donation. Copyright © 2018 Elsevier Inc.
