A hálózatos iparágakban, ahogy a postai szolgáltatásoknál is, a forgalomban lévő készpénz nagyméretű működőtőkét jelenthet. A Magyar Posta a levél- és csomagkézbesítésen kívül jelentős készpénzforgalmat bonyolít le: nyugdíjakat, segélyeket és készpénz-átutalási megbízásokat továbbít. A forgalom napi ingadozása a vállalat likvideszköz-igényét jelentősen meghatározza. A posta esetében a postahivatalok készpénzgazdálkodása jól működő hüvelykujjszabályokon keresztül történik, ezek a szabályok döntési teret hagynak a hálózat heterogén egyedi szereplőinek. Az egyedi készletezési viselkedést a vállalati működőtőke meghatározásakor figyelembe kell venni. A tanulmány az egyedi készletezési szokások modellezésére új módszertant ajánl, majd a viselkedésmintákat csoportosítva a pénzkészletezésnek, a vállalati működőtőke szintjének és a vállalati likviditási pozíciónak a kapcsolatát elemzi. / === / The cash in circulation within network industries such as post-office services can repre-sent a sizeable quantity of operating capital. The Hungarian Post Office, besides han-dling mail, handles a significant amount of cash turnover, forwarding pensions, welfare benefits, and cash orders. Fluctuation in the daily volume of these is a strong factor in determining the company's liquidity requirements. The management of cash in post of-fices is governed by rules of thumb that operate well; the regulations leave decision-making scope for the diverse individual actors in the network. Attention has to be paid to individual cash holding when determining the corporate operating capital. The study suggests a new methodology for modelling the individual cash-holding habits, and goes on to group the behaviour patterns by analysing the connection between cash holding, level of corporate operating capital, and corporate liquidity position.

A közelmúltban készült kutatásban a szerzők azt vizsgálták, hogy a kis- és középvállalkozásokban az elektronikus banki ügyintézéssel kapcsolatban milyen szokásaik, attitűdjeik és jövőképeik alakultak ki. A több mint ötszáz KKV-vezetővel készült interjú alapján elmondható, hogy a vállalkozás elektronikus ügyintézéssel kapcsolatos hozzáállása egyáltalán nem, vagy csak nagyon gyenge mértékben hozható összefüggésbe a cég objektív tulajdonságaival, például a létszámmal, az árbevétellel vagy a tevékenységi körrel. Egyértelműen látszik, hogy már az elektronikus banki ügyintézéssel kapcsolatos fogalmak értelmezése is problémát jelent a KKV-vezetők egy részénél. A tudásbeli hiányosságok pedig egyértelműen befolyásolják az e-banking attitűdöt és a használati szokásokat, pedig az elektronikus csatornákat használók elégedettsége minden vizsgált bank ügyfeleinek esetében 80% fölötti értékeket mutat. Így a legfontosabb kérdés az, hogy miként lehetne megértetni a „Szkeptikusok”-kal és a „Mérlegelők”-kel, hogy érdemes a „Haladók” klaszterébe tartozni. Az ügyfélelégedettség sikertényezői egyértelműen a biztonság, az időben és térben széles körű elérhetőség és az egyszerű használat. A válaszadók jövőképe szerint a banki szolgáltatások igénybevétele egyre inkább eltolódik majd az elektronikus csatornák irányába. Jelen cikkben a kutatás legfontosabb tanulságait mutatják be a szerzők. _________ The authors’ research was conducted to explore the ebanking attitudes, habits and vision of small and medium enterprises. By the interviews of more than 500 managers of SMEs, it is concluded that e-banking attitudes are not, or not significantly related to the objective characteristics of the enterprises, e.g. to the number of employment, the revenues or its activities. It became clear, that the interpretation of the specific e-banking terms means an important problem for some managers. The deficiencies of knowledge have direct effects on e-banking attitude and the use of electronic banking methods of the enterprises, although the value of the satisfaction level is above 80% among the customers of each examined banks. Thus, the main objective is to explain to the “Scepticals” and the “Considerers” the benefits of the “Progressives” cluster. The most important success factors of customer satisfaction are safety, availability in time and space and ease of use. According to the vision of the respondents, banking services will probably be shifted towards e-channels. In this study, the most important findings of our researches were summarized.

Accidents are the leading cause of death among children. Compliance with safety measures have been shown to reduce morbidity and mortality in children. However, Hispanic parents and children have not been adequately studied in the literature in regard to trauma and safety habits utilized. In this exploratory-descriptive study, a convenience sample of 48 Hispanic parents were questioned about their child's activities. The purpose was to determine what safety equipment was used during these activities and how often they were used. Responses to an English/Spanish questionnaire were summarized by frequencies and percentages. Findings suggested that these Hispanic children were at risk for injury due to a low percentage of children wearing the necessary protective equipment. Therefore, education must stress consistent use of safety equipment if injuries are to be prevented. ^

The purpose of this study was to demonstrate if the academic assistance program Supplemental Instruction (SI) facilitates the acquisition of effective study behaviors through strategies that transcend simple double-exposure to the course material. Its advocates claim it increases academic achievement using learner-centered knowledge and acquisition of effective study behaviors. SI sessions are specifically related to particular courses that students are taking. Sessions are facilitated by the SI leader who has taken the subject matter course in the past. Students review the content of the previous subject matter class using collaborative learning strategies coordinated by a SI leader. In addition, the SI leader models appropriate study behaviors in his or her interactions with the students. ^ An instructor at a large Florida community college who taught five classes of an Anatomy & Physiology I course (traditionally supported by SI) was identified. Two of the classes were randomly selected to participate in SI activities, and two classes were random chosen to participate in alternate, computer-based activities that dealt with the course content, but did not include work in developing students' study behaviors. These treatments were carried out over the course of an entire semester. Participation was mandatory. ^ Data were collected on two variables. Academic achievement in anatomy and physiology content was measured both pre- and post-treatment using an instructor developed examination. Student study behaviors were measured using pre- and post-treatment administration of the Study Behavior Inventory, a valid and reliable instrument that provides scores on three categories of study behaviors: (a) Academic self-efficacy, (b) Preparation for routine academic tasks, and (c) Preparation for long range academic tasks. Measures obtained at the end of the semester of treatment revealed no significant differences between the SI and alternative treatment groups in post-treatment achievement test score and the post-treatment scores on the three study behaviors categories when adjusted for pre-treatment scores. ^ These results suggest that the development of appropriate study behaviors requires more time than SI, as it is now implemented, can provide. In addition, results indicate that improved academic achievement may be attained through any number of means that include repeated exposure to course material. ^

The coastal wetlands of northeastern Florida Bay are seasonally-inundated dwarf mangrove habitat and serve as a primary foraging ground for wading birds nesting in Florida Bay. A common paradigm in pulse-inundated wetlands is that prey base fishes increase in abundance while the wetland is flooded and then become highly concentrated in deeper water refuges as water levels recede, becoming highly available to wading birds whose nesting success depends on these concentrations. Although widely accepted, the relationship between water levels, prey availability and nesting success has rarely been quantified. I examine this paradigm using Roseate Spoonbills that nest on the islands in northeastern Florida Bay and forage on the mainland. Spoonbill nesting success and water levels on their foraging grounds have been monitored since 1987 and prey base fishes have been systematically sampled at as many as 10 known spoonbill foraging sites since 1990. Results demonstrated that the relationship between water level and prey abundance was not linear but rather there is likely a threshold, or series of thresholds, in water level that result in concentrated prey. Furthermore, the study indicates that spoonbills require water level-induced prey concentrations in order to have enough food available to successfully raise young.

BACKGROUND: The Pro Children Eating Habits Questionnaire has been evaluated as a valid and reliable tool in Europe to measure determinants of fruit and vegetable intake for children; however, it has not been validation for United States populations. The purpose of this study was to (1) assess the reliability and discrimination validity of fruit and vegetable correlates for the Pro Children Eating Habits Questionnaire; (2) investigate the predictive validity of determinants of fruit and vegetable consumption for multi-ethnic elementary school children; and, (3) to assess the association of social determinants with fruit and vegetable consumption. METHODS: One hundred and thirty elementary school students from the 3rd and 5th grades completed this cross-sectional study. RESULTS: Fruit and vegetable determinants, had satisfactory internal consistencies. No differences were found between the test and the retest for the individual questions with the exception of the question for mean perceived vegetable intake. The discriminatory validity indicated the questionnaire could show differences across grade and gender levels for barriers of fruit and vegetables but not for other factors. Grade together with gender explained barriers to eating fruit and vegetables. Greater availability of fruit in the home and school was associated with higher frequency of consumption. CONCLUSIONS: The results of this study indicate the Pro-Children Eating Habits Questionnaire may be a reliable and valid tool for assessing fruit and vegetable consumption of children in the United States.

Through bioturbation, the macrofauna mediate chemical, physical and biological processes in marine benthic ecosystems. Because of the importance of bioturbation as ecosystem mediator, various studies have been conducted on bioturbation intensity and depth, and the relation of bioturbation processes to environmental condition and ecosystem state. This thesis builds on those previous studies, using a standard field and analytical protocol and by expanding the geographical scale to three climatic regions along Canada’s East Coast and Arctic margins, the Arctic Archipelago, the coastal Subarctic (Labrador Fjords), and the temperate continental climate zone (Gulf of Maine and adjacent Scotian shelf/slope). This Ph.D. study provides a comprehensive assessment of environmental influences on bioturbation along gradients in latitude and ocean depth. Bioturbation intensity, mixing depth, and bioturbation structures were studied in relation to the quantity and quality of potential food sources (organic matter) and substrate characteristics to gain an understanding of the environmental controls on bioturbation in these regions. The three main research chapters of this thesis are divided based on the contrasting climatic and geographical regions studied. The analytical approach included seabed sampling with a boxcorer, describing the sedimentary fabric and bioturbation structures by X-radiography, estimating bioturbation intensity and depth applying a biodiffusion model to particle tracer profiles of ²¹⁰Pbₓs, ²²⁸Thₓs, ²³⁴Thₓs, and chlorophyll-a, and analyzing benthic organic matter and substrate characteristics. Strong regional and cross-climatic relations of bioturbation processes with combinations of environmental factors were observed. In particular, bioturbation depth and the vertical extent of bioturbation structures responded to the environmental patterns observed and, therefore, represented potentially applicable predictors of environmental conditions and ecosystem state. The results of this Ph.D. study may be further extended to other geographical regions with similar environmental characteristics to predict the effects of benthic habitat alterations through environmental stresses on a global scale. Integrated with biological data produced by fellow CHONe scientists the presented data may provide valuable information about functional roles of macrofaunal species and community traits in marine benthic ecosystems along Canada’s extensive East Coast and Arctic margins.

Background: To determine the portion sizes of traditional and non-traditional foods being consumed by Inuit adults in three remote communities in Nunavut, Canada. Methods. A cross-sectional study was carried out between June and October, 2008. Trained field workers collected dietary data using a culturally appropriate, validated quantitative food frequency questionnaire (QFFQ) developed specifically for the study population. Results: Caribou, muktuk (whale blubber and skin) and Arctic char (salmon family), were the most commonly consumed traditional foods; mean portion sizes for traditional foods ranged from 10 g for fermented seal fat to 424 g for fried caribou. Fried bannock and white bread were consumed by >85% of participants; mean portion sizes for these foods were 189 g and 70 g, respectively. Sugar-sweetened beverages and energy-dense, nutrient-poor foods were also widely consumed. Mean portion sizes for regular pop and sweetened juices with added sugar were 663 g and 572 g, respectively. Mean portion sizes for potato chips, pilot biscuits, cakes, chocolate and cookies were 59 g, 59 g, 106 g, 59 g, and 46 g, respectively. Conclusions: The present study provides further evidence of the nutrition transition that is occurring among Inuit in the Canadian Arctic. It also highlights a number of foods and beverages that could be targeted in future nutritional intervention programs aimed at obesity and diet-related chronic disease prevention in these and other Inuit communities.

The impact of environmental pollution on the homeostasis of sea turtles remains scarce, particularly in the southern Gulf of Mexico. As many municipalities do not rely on a waste treatment plant along the coastline of the Yucatan Peninsula, the vulnerability of these specimens could results enhanced. We searched for relationships between presence of organochlorine pesticides (OCP) and the level of several oxidative and pollutant stress indicators of the hawksbill sea turtle (Eretmochelys imbricata) during the egg-laying period 2010 at Punta Xen (Campeche, Mexico). Endosulfans, aldrin related (aldrin, endrin, dieldrin, endrin ketone, endrin aldehyde) and dichlorodiphenyldichloroethylene (DDT) families were detected in 17, 21 and 26 of the 30 sampled sea turtles, respectively. Significant correlation existed between the size of sea turtles with the concentration of methoxychlor, cholinesterase activity in plasma and heptachlors family, and catalase activity and hexachlorohexane family. Cholinesterase activity in washed erythrocytes and lipid peroxidation were positively correlated with glutathione reductase activity. Antioxidant enzyme actions seem adequate as no lipids damages were correlated with any OCPs. Future studies are necessary to evaluate the effect of OCPs on males of the area because of the significant detection of methoxychlor that target endocrine functioning and increase its concentration with size of the sea turtles.

This article analyses the influence that different criticism stages of proceedings exert in the habits of theatre attendance. The study is based on the survey carried out specifically for this research in which 210 people, who attended a theatrical representation, were interviewed in three different theatres in the city of Valencia. The study has revealed the mouth to mouth importance in the decision of attending the theatre and its stronger influence on the audiences who less frequently go to theatrical representations. The results obtained have also made clear the existence of a narrow relation between the advice effect of the theatre critics and the patterns of attendance to the theatre, just like its bigger influence between theatres with commercial orientation and those which are addressed to the broad audiences.

INTRODUCTION: The differential associations of beer, wine, and spirit consumption on cardiovascular risk found in observational studies may be confounded by diet. We described and compared dietary intake and diet quality according to alcoholic beverage preference in European elderly.
METHODS: From the Consortium on Health and Ageing: Network of Cohorts in Europe and the United States (CHANCES), seven European cohorts were included, i.e. four sub-cohorts from EPIC-Elderly, the SENECA Study, the Zutphen Elderly Study, and the Rotterdam Study. Harmonized data of 29,423 elderly participants from 14 European countries were analyzed. Baseline data on consumption of beer, wine, and spirits, and dietary intake were collected with questionnaires. Diet quality was assessed using the Healthy Diet Indicator (HDI). Intakes and scores across categories of alcoholic beverage preference (beer, wine, spirit, no preference, non-consumers) were adjusted for age, sex, socio-economic status, self-reported prevalent diseases, and lifestyle factors. Cohort-specific mean intakes and scores were calculated as well as weighted means combining all cohorts.
RESULTS: In 5 of 7 cohorts, persons with a wine preference formed the largest group. After multivariate adjustment, persons with a wine preference tended to have a higher HDI score and intake of healthy foods in most cohorts, but differences were small. The weighted estimates of all cohorts combined revealed that non-consumers had the highest fruit and vegetable intake, followed by wine consumers. Non-consumers and persons with no specific preference had a higher HDI score, spirit consumers the lowest. However, overall diet quality as measured by HDI did not differ greatly across alcoholic beverage preference categories.
DISCUSSION: This study using harmonized data from ~30,000 elderly from 14 European countries showed that, after multivariate adjustment, dietary habits and diet quality did not differ greatly according to alcoholic beverage preference.

[EN] Nesting beach surveys are the most widely implemented monitoring tool in use by the global sea turtle community and are an important component of a comprehensive program to assess and monitor the status of sea turtle populations. These assessments are necessary to evaluate the effects of recovery and conservation activities that are being implemented at all life history stages. Monitoring techniques employed on nesting beaches range from highly structured standardized sampling to “snapshots” of nesting activity within a nesting season. Very long-term nest counts data (more than twenty years) were analyzed for some turtle populations.

[EN] Different kinds of physical anomalies are frequently observed in any sea turtle breeding population. Nesting beaches are an excellent place to study the injuries and defects that occur in adult females. The archipelago of Cape Verde is situated about 500 km of Senegal, West Africa. Boavista is the eastern most island and may constitute the most important nesting area for the loggerhead turtle in the archipelago. The studies conducted from 1998 to 2004 indicate that Cape Verde might account for one of the most important loggerheads populations in the eastern Atlantic. The nesting females in Boavista were surveyed during the 2004 season, in order to (1) know the health status of the population (2) determine the effects of physical anomalies on nesting behaviour and (3) determine the possible origin of the injuries observed.

[EN] Sea turtles exhibit a strong natal homing associated with a high nesting site philopatry. Mark-recapture and genetic studies confirm these patterns suggesting differences among and within species. In the present study, we have analysed the degree of nest site fidelity of a loggerhead population nesting on the islands of Cape Verde and have evaluated the existence of intrapopulational variability in this trait. The loggerhead is the only sea turtle species that nests in Cape Verde, and 15,000–25,000 nests per season have been estimated for the whole archipelago.
