Care Transitions, Integration and Leadership

Mannix, Glenda Victoria 03 September 2013 (has links)
This paper examines three important and interrelated concepts pertinent to the provision of high quality health care namely care transitions, integration and leadership. The population focus is seniors over the age of sixty-five living within the geographical boundary who access care and services across the continuum. The examination illustrates some of the current challenges, opportunities, barriers and gaps identified in the literature and to draw out pertinent evidence to support future practices. Nurse leaders are well positioned to make a significant contribution to patient-centered care and integration by drawing together the strands of the management of care systems, cross-boundary working and thinking and the effective allocation of resources. / Graduate / 5069

Pre-service Elementary Mathematics Teachers

Kaplan, Merve 01 December 2010 (has links) (PDF)
Mathematics education could and should benefit from technology in order to improve teaching and learning, particularly in topics where visualizations and connections to other concepts are needed. Handheld technologies such as graphing calculators can provide students with visualization, confirmation and exploration of problems and concepts they are learning. Handheld graphing technologies have been taken place widely in elementary and secondary level mathematics courses and considered to be beneficial in various means in mathematics education. Mathematics teachers have a crucial role in the use of GCs in mathematics classrooms. Therefore, pre-service teachers&rsquo / use of GCs and their views on the use of the tool in mathematics learning are considered to be valuable. The purpose of this study was to investigate the difficulties pre-service elementary mathematics teachers face, and the benefits and constraints they emphasize while learning elementary school algebra through using the Casio Classpad after receiving an instruction with graphing calculators. The graphing calculator used in the present study is the Casio Classpad 330, which is an evolved handheld device combining features of graphing calculators, dynamic geometry environment, computer algebra systems and more. The following two research problems guided the study: What are the difficulties do pre-service elementary mathematics teachers face while using Classpad in learning elementary school algebra after receiving an instruction with graphing calculators? What benefits and constraints do pre-service elementary mathematics teachers emphasize while learning elementary school algebra through using Classpad after receiving an instruction with graphing calculators? With the aim of investigating the views of a group of pre-service elementary mathematics teachers, qualitative research strategies were used. The data was collected and analyzed by means of a case study design. Classroom observations, a questionnaire, and focus group interviews were the main data sources of the existing study. The study was carried out with 21 pre-service elementary mathematics teachers. In the classroom studies elementary level algebra was taught to the participants with the use of Classpad as a main tool by giving one tool to each of the participants. Classroom observations ended in five weeks &ndash / 20 courses &ndash / including one week of a training period. After the classroom observations, participants filled out a questionnaire including five open-ended questions about the classroom studies. Finally, data collection procedure was ended with three focus group interviews. The data was analyzed with qualitative means by transcribing and analyzing the observation records, answers of the questionnaire, and records of the three interviews. Results revealed that pre-service teachers&rsquo / view Classpad in three categories / as a personal tool, as an educational tool, and the relationship between CP and motivation. They viewed CP as a personal tool that they were eager to use the tool in every level of mathematics from elementary to mastering degrees. As an educational tool, they preferred to use the tool as a teacher by giving some cautions that teachers and students should be careful with. Lastly, they considered that the tool has a positive effect on motivation when used appropriately. Pre-service elementary mathematics teachers faced some difficulties in the beginning courses of the classroom studies which was their learning period of how to use CP and they overcome most of the difficulties at the end of the classroom studies. As the new elementary school level mathematics curriculum encourages the use of various technologies in teaching and learning of mathematics, the results of this study will have useful implications for mathematics teachers and curriculum developers.

An empirical investigation of measures to enhance intra-Africa trade

Wang'ombe, Wangari January 2013 (has links)
Trade is largely considered a driving force of economic growth and development of nations. To this end, there is vast and far-reaching research on the subject, especially on matters international. However, research on intra-African trade is lacking in comparison to research on trade amongst the rest of the world, not just developed, but also developing countries alike. That aside there are numerous efforts put in place to enhance and encourage trade within and without the continent. The research presented in this thesis aims to investigate and address three key issues specific to intra-Africa trade. The questions asked are: are the measures currently in place successful in the promotion of intra-Africa trade; is the continent ready for measures about to be implemented and after all that, is trade really the key driving force for economic growth and development within Africa? To answer these questions, the research presented here in this thesis employs the gravity modelling approach, the G-PPP test and develops a macro-economic model which is applied to the Kenyan economy. The results indicate that; yes, trade is significant and important in determining economic growth, and while measures taken thus far such as the creation of Economic Integrations have not been as successful as was envisioned, trade openness continues to be among the most important ways in which trade is encouraged and enhanced, to this end, although the continent is yet to fulfil all the requirements for the formation of a full-blown Economic Union, it is ready for drastic measures such as the formation of a currency union. Literature reveals that this could form the basis of hastening complete integration and harmonization of all systems of the participating economies, thereby benefiting not just trade but also all other sectors of the economies.

Mogući efekti integracije u EU na poljoprivredu Srbije / Possible effects of integration into European Union on Serbian agriculture

Milovanović Miloš 29 September 2016 (has links)
<p>&nbsp;Osnovni cilj ove disertacije je prikaže efekte integracionih procesa na poljoprivredu Srbije. Poljoprivreda Srbije je sektor privrede koji sa sobom nosi velike potencijale zasnovane na resursima, tradiciji u bavljenju ovom granom privrede, povoljnoj klimi i odličnoj geostrate&scaron;koj poziciji zemlje, te su sve projekcije daljih razvojnih potencijala od izuzetnog značaja za pro&scaron;irivanje fonda naučnog i stručnog znanja. Međunarodni integracioni procesi u koje je na&scaron;a zemlja uključena, ali i oni kojih je Republika Srbija već postala član, u velikoj meri oblikuju poljoprivredno-prehrambeni kompleks zemlje. Takođe, neki od njih (a pre svega integracija u Evropsku uniju) posebnu pažnju posvećuju pitanjima ruralnog razvoja. Tokom procesa pristupa, kao i samim kasnijim članstvom, zemlja dobija (ili gubi) mogućnosti primene određenih mera politike u svrhu podsticanja razvoja poljoprivrede i ruralnog razvoja. Na taj način počinje oblikovanje ovog sektora privrede putem instrumenata koji su zajednički za sve članove multilateralnih sistema kojih zemlja postaje član. U ovoj disertaciji su kori&scaron;ćena dva metoda za predviđanje razvoja poljoprivrednog razvoja Srbije. Prvi pristup je zasnovan na PEATSIM modelu. PEATSIM (Partial Equilibrium Agricultural Trading Simulation Model) predstavlja Model parcijalne uravnotežene poljoprivredne trgovinske simulacije koji, na osnovu zadatih makroekonomskih podataka iz prethodnog desetogodi&scaron;njeg perioda i uz pretpostavku konstantne poljoprivredne i ekonomske politike pruža simulaciju budućih trgovinskih kretanja za odabrane poljoprivredne proizvode i regione porekla ovih proizvoda. Pored PEATSIM modela, primenjen je i tzv. ARIMA model (Autoregressive Integrated Moving Average). U analizi vremenskih serija od naročitog je interesovanja, sa aspekta ovog rada, posebna klasa stohastičkih procesa. Do nje se dolazi nametanjem izvesnih ograničenja na proces. Tako se defini&scaron;u stacionarne stohastičke procese na osnovu kojih se razvija klasa parametarskih stacionarnih modela vremenskih serija. Kao takav, ARIMA model je &scaron;iroko primenjivan za predviđanje budućih tokova poljoprivredne trgovine, kako na agregatnom nivou, tako i na nivou pojedinačnih proizvoda. Drugi pristup je zasnovan na komparativnoj analizi iskustava zemalja u okruženju (Poljska, Mađarska, Slovenija, Bugarska i Rumunija) koja su pro&scaron;la slične integracione procese koji predstoje Srbiji. Ova iskustva i efekti integracija na poljoprivredu su kori&scaron;ćena za dragoceni materijal za dono&scaron;enje zaključka i mera za redefinisanje agrarne politike Srbije. Posebno su značajni pregledi ograničenja domaće agrarne politike, osnovni pravci delovanja, neophodne institucionalne promene i očekivani efekti punog integrisanja Srbije u međunarodne institucije i organizacije.</p> / <p>&nbsp;Main goal of this dissertation is to present integration processes effects on agriculture of Serbia. Serbian agriculture is sector of economy with great potential built on resources, tradition in this sector, favourable climate and excellent geostrategic position of the country so every projection of further development of potentials is of vital importance for expanding scientific and experts knowledge in the area. International integration processes in which our country participates, together with organizations that Serbia is already member of, shape agri food complex of the country to a large extent. Also, some of these processes (in first place integration in European Union) are devoting special attention on issues related to rural development. During accession process and later membership, country gets (or looses) possibilities of implementation certain policy measures for supporting agriculture and rural development. By this starts shaping of this sector of economy using common instruments for all members of multilalateral systems country is becoming a member. Two methods for forecasting agricultural development of Serbia are used in this dissertation. First one is based on PEATSIM model. PEATSIM (Partial Equilibrium Agricultural Trading Simulation Model) presents model of partial balanced agricultural trade simulation which, based on set macroeconomic data from past ten years period and under assumption of constant future agricultural and economic policy, provides simulation of future trade flows for selected agricultural products and originating regions. Apart from PETSIM model it is also applied so called ARIMA model (Autoregressive Integrated Moving Average). In time series analyses it is of paramount importance, from this dissertation aspect, special class of stochastic processes which is reached by imputing certain limitations to the process. This way, stationary stochastic processes are defined which serve as a basis for development of classes of parameter stationary time series models. As such, ARIMA model has been widely used for forecasting future agricultural trade flows, on aggregate and individual products level. Second approach is based on comparative analyses of neighbouring countries experiences (Poland, Hungary, Slovenia, Bulgaria and Romania) which went through similar integrations processes which are ahead of Serbia. These experiences and agricultural integration effects are used as valuable material for defining conclusions and measures for redefinition of Serbian agricultural policy. Particularly important are limitatations of domestic agrarian policy, basic directions of interventions, necessary institutional changes and expected effects of complete Serbian integration in international institutions and organizations.</p>

An Empirical Examination of Multinational Corporations'(MNCs)Integration of Tourism Market Development Strategies(TMDS) With African Host Countries' Needs and Expectations

Iroegbu, Henry Godson U. 17 January 2002 (has links)
This exploratory study examined the different tourism market development strategies that tourism Multinational Corporations (MNCs) implement in their operations in African host countries. It empirically investigated the existence of any relationships between tourism MNCs’ market development strategies and the “Needs and Expectations of African host countries.” Also, it investigated the influences of external environmental factors on tourism MNCs’ tourism market strategic choice. Its sample population were top management executives of tourism MNCs‘ with operations in the African market. The unit of analysis was the corporation. The sample frame was an exhaustive list of tourism MNCs with operations in the African region. The initial sample size was 106 tourism MNCs’ executives. Thirty-seven of them responded to a mail in survey questionnaire. Two of the questionnaires were discarded due to numerous missing data. Thus, there were 35 usable questionnaires for data analysis, which is a response rate of 33%. The study results identified relationships between the integration of Multinational Corporations’ (MNCs) tourism market development strategies with the needs and expectations of developing African host countries, and their successful performance in those host countries in terms of growth in operations and profitability. It revealed that significant differences exist among the market development strategies on the factors of needs and expectations of African host countries. The significant factors were community participation, local entrepreneurship, and job and national security. Also, the economic development factor was observed to be partially significant. This study also identified free trade economy in the African host countries as a significant factor on the influence of external environment. The framework of this study is embedded in the underlying theories of international strategic management, international business, international development, and needs and expectations. The study’s final conceptual model depicts the significant factors of African host countries’ needs and expectations, the tourism market development strategies, an integration of the two concepts and the resultant tourism MNCs successful performance. This research study investigated MNCs in all sectors of the tourism industry. And the findings have shown that for the tourism MNCs to be successful in their African host countries, they should be sensitive to the identified sectors, namely economic development, community participation, local entrepreneurship, and job and national security measures. Also, they should exert more efforts in exploring African free trade economies for their business locations in the region. / Ph. D.

Metody identifikace geneticky souvisejících planetek / Identification methods of genetically related asteroids

Fatka, Petr January 2020 (has links)
In this thesis, I describe the main ideas and summarize the results of four refereed papers I contributed to (three times as the second author and once as the first author). The first step of each of these papers was the identification of genetically related asteroid and their membership confirmation. Since members of asteroid pairs and clusters have a very similar heliocentric orbits, we employed and further developed methods based on backward orbital integrations. The chronologically first paper Pravec et al. (2018) deals with asteroid clusters and their similarity to asteroid pairs. The second paper Pravec et al. (2019) is a complex study of 93 asteroid pairs with many interesting results, such as the existence of binary asteroids among asteroid pairs. The third paper Moskovitz et al. (2019) deals with an identification of asteroid pairs in the near-Earth population and a detail study of two probable asteroid pairs. The fourth paper, Fatka et al. (2020), studies the phenomenon of cascade disruption in asteroid clusters, which results in multiple generations (with different ages) of escaped secondaries in some asteroid clusters.

Scalable platform for health service integrations / Skalbart system för integration med hälsotjänster

Hammer, Joakim, Lind, Olle January 2013 (has links)
This thesis was performed at the company ShapeUp Club located in Stockholm, Sweden. ShapeUp Club offers a digital calorie counter service for the web, iOS and Android with data synchronization across the platforms. ShapeUp Club wants to provide their users with the option to synchronize data between ShapeUp Club and external health services. The objective for this thesis has been to develop an extension to ShapeUp Clubs current backend platform where new external health services can be plugged-in quickly and scalable. External partner APIs will be examined and implemented in the system to validate the functionality of the system. The amount of code needed to plug-in a service should be as minimal as possible for a developer to quickly add another service. To allow for scalability the platform also needs to adapt logic for how often users should be allowed to poll for data from their connected services, to minimize the database load for all parts. To handle these demands, an extension to ShapeUp Club’s current backend solution was built using the Django framework for Python. By providing a generic base class that new services inherit from, the amount of code necessary for implementing a new service is reduced to methods for API- requests, authorization and serialization of data. To reduce the number of redundant poll requests, users are placed into groups. Each group is a cluster of users with similar frequency of updates. Django’s cache framework is used to handle the concurrency of the sync tasks, which locks a user from syncing the same partner in parallel. / Detta examensarbete har utförts hos företaget ShapeUp Club i Stockholm. ShapeUp Club erbjuder en digital kaloriräknare för webben, iOS och Android med synkronisering av data mellan dessa plattformar. ShapeUp Club vill kunna erbjuda sina kunder möjligheten att synkronisera data mellan ShapeUp Club och andra externa hälsotjänster. Målet med detta projekt har varit att implementera en ny tjänst till ShapeUp Clubs nuvarande backend-lösning där externa hälsotjänster snabbt och skalbart kan implementeras. Externa hälso-API:er har utvärderats och implementerats i samband med utvecklingen av den nya backendtjänsten, för att validera dess funktionalitet. Mängden kod som behövs för att implementera en hälsotjänst bör vara så minimal som möjligt för att utvecklare snabbt ska kunna lägga till ytterligare tjänster. För att systemet ska vara skalbart måste logik finnas för hur ofta användare ska tillåtas att fråga efter data mot de tjänster de har valt att synkronisera mot. För att tillfredställa dessa behov har en utökning av ShapeUp Clubs nuvarande backend-lösning byggts med ramverket Django för Python. Genom att ha en större, generisk klass som nya implementeringar ärver från så har mängden nödvändig kod för varje hälsotjänst-implementering minskats till metoder för API-anrop, autentisering och serialisering av data. För att minska antalet “onödiga” poll-anrop så placerar vi användare i olika grupper beroende på om deras poll-anrop frekvent återvänder utan någon ny information. De olika grupperna bestämmer sedan hur länge användarna måste vänta innan de tillåts göra nya poll-anrop.
