Diet change—a solution to reduce water use?
No full textWater and land resources are under increasing pressure in many parts of the globe. Diet change has been suggested as a measure to contribute to adequate food security for the growing population. This paper assesses the impact of diet change on the blue and green water footprints of food consumption. We first compare the water consumption of the current diets with that of a scenario where dietary guidelines are followed. Then, we assess these footprints by applying four scenarios in which we gradually limit the amount of protein from animal products to 50%, 25%, 12.5% and finally 0% of the total protein intake. We find that the current water use at the global scale would be sufficient to secure a recommended diet and worldwide energy intake. Reducing the animal product contribution in the diet would decrease global green water consumption by 6%, 11%, 15% and 21% within the four applied scenarios, while for blue water, the reductions would be 4%, 6%, 9% and 14%. In Latin America, Europe, Central and Eastern Asia and Sub-Saharan Africa, diet change mainly reduces green water use, while in the Middle East region, North America, Australia and Oceania, both blue and green water footprints decrease considerably. At the same time, in South and Southeast Asia, diet change does not result in decreased water use. Our results show that reducing animal products in the human diet offers the potential to save water resources, up to the amount currently required to feed 1.8 billion additional people globally; however, our results show that the adjustments should be considered on a local level
Motivation at the workplace
Get PDFThe purpose of this master’s thesis was to produce information of the target department’s state of motivation. Also, to explain the issues that affect motivation in a workplace. The objective of this theses was to improve employee’s motivation proactively that can lead to engagement to the employee company. The research was targeted to one specific department that consisted of 31 employees at the time of the research. In the target department there had been problems with high turnover of employees. Motivation was seen by the author as an important theme in working life and the goal of this thesis was to find out issues that explain motivation.
The combination of real-life target department’s experience and theoretical and conceptual background was seen as an appropriate way to research the subject. The theoretical part of the thesis was constructed by getting to know the self-determination theory and the concepts of knowledge work and engagement. The research was conducted by a mixed method research design. Data was gathered by a survey by using a questionnaire.
The results of this thesis showed that the content of the work, ability to influence one’s own work and pay and benefits were the most important issues that affected motivation in the target organization. The theory used and the concepts analysed supports the findings of this research.
The state of motivation was seen to be on a good level in the target organization but there came up some suggestions that could help to maintain and develop good motivation in the future. The most important lesson was seen as being the importance of a more individualistic view to motivation needs. Conversations between the team-leader and employee were seen as an important way to find out what could be done to improve overall motivation.
In the future, this type of motivation survey can be used to repeatedly give information of the status of motivation and lead to deeper conversations inside the department. This is seen as a tool to increase engagement to the organization

Napromieniając chorego na aparacie terapeutycznym nie ma możliwości ustawienia aparatu w inny sposób niż zostało to zaplanowane. W systemie zintegrowanego zarządzania radioterapia Varis można dokładnie zaplanować nie tylko sposób leczenia, ale również godzinę, o której chory powinien zgłosić się na aparat terapeutyczny. System Varis pozwala także wykreować róiżnego rodzaju raporty dotyczące pacjentów na podstawie danych zgromadzonych na serwerach. Nierozerwalna Częścią Varisa jest system Vision. Pozwala on na kontrole i weryfikacje ułożenia pacjenta podczas terapii. Służą do tego zdjęcia z symulatora i wykonywane komputerowo zdjęcia weryfikacyjne. System Vision pozwala na bardzo precyzyjna obróbkę otrzymywanych obrazów. Systemy Varis i Vision eliminują lub korygują ewentualne błędy wynikające z niepoprawnego egzekwowania zaplanowanych parametrów fizycznych. Podczas sesji przedstawione zostaną własne doświadczenia Kliniki w stosowaniu wymienionego systemu

From food insufficiency towards trade dependency: a historical analysis of global food availability
No full textAchieving global food security is one of the major challenges of the coming decades. In order to tackle future food security challenges we must understand the past. This study presents a historical analysis of global food availability, one of the key elements of food security. By calculating national level dietary energy supply and production for nine time steps during 1965–2005 we classify countries based on their food availability, food self-sufficiency and food trade. We also look at how diets have changed during this period with regard to supply of animal based calories. Our results show that food availability has increased substantially both in absolute and relative terms. The percentage of population living in countries with sufficient food supply (>2500 kcal/cap/d) has almost doubled from 33% in 1965 to 61% in 2005. The population living with critically low food supply (15% of dietary energy supply) increased from 33% to over 50%. While food supply has increased globally, food self-sufficiency (domestic production>2500 kcal/cap/d) has not changed remarkably. In the beginning of the study period insufficient domestic production meant insufficient food supply, but in recent years the deficit has been increasingly compensated by rising food imports. This highlights the growing importance of food trade, either for food supply in importing countries or as a source of income for exporters. Our results provide a basis for understanding past global food system dynamics which, in turn, can benefit research on future food security.Peer reviewe

No full textSuperdiversità su internet un caso dalla Cina
No full textIn questo articolo, pubblicato per la prima volta nel 2011 su «Diversities», rivista accademica edita da UNESCO fino al 2013, e aggiornato in occasione della sua ripubblicazione su KABUL magazine, le autrici Piia Varis e Xuan Wang analizzano il web come spazio della superdiversità per antonomasia, in cui singoli individui, gruppi e intere comunità possono trovare infinite opportunità di espressione di sé. In altre parole, Internet rappresenta in potenza una safe zone per tutte le sottoculture e le minoranze che non sempre nello spazio fisico possono o riescono a esprimersi. Su Internet, tuttavia, la diversità non è garantita e preservata in tutte le occasioni, e si scontra anzi spesso con forme di controllo e di censura, nonché con i tentativi di normativizzazione attuati dalla politica e dalle società. Tali aspetti vengono scandagliati in profondità dalle due ricercatrici attraverso l’analisi di uno specifico caso studio, quello del rapper pechinese MC Liangliang, che attraverso la sua attività di comunicazione ed espressione di sé online si configura quale esempio significativo del fenomeno contemporaneo dell’hip hop globale di Internet, uno spazio e una cultura superdiversi contraddistinti da un proprio linguaggio specifico (quello che le due autrici definiscono appunto un “super-vernacolare globale”) e da simboli riconoscibili e ben codificati a partire da un immaginario culturale transnazionale e condiviso
