The carbon-saving behaviour of residential households
The housing sector in 2004 was accountable for about 30% of total UK carbon emissions. The magnitude of this figure represents a significant imperative for policymakers to act on the sector through behavioural change strategies. Energy efficiency in households might easily be considered as driven mainly by economic motives, but this would not explain why even cost-free behavioural changes, like switching the lights off more often, are not adopted more widely. Literature has mainly concentrated either on the economic motives of pro-environmental behaviours or on the relevance of attitudes to shape them. Little has been said so far on the interaction between attitudes and the so called contextual factors. Diekmann and Presindörfer (2003) outlined the “low-cost hypothesis” which argues that pro-environmental behaviours are driven by pro-environmental attitudes only in the presence of low costs. However, little is known about households’ perceptions of costs and benefits in relation to energy saving behaviour. We propose to develop the low-cost hypothesis with a theoretical approach
integrating attitudinal research and rational choice literature and explaining the interaction between tangible and intangible costs and benefits.Furthermore, the importance of resources such as education, information and income is highlighted in order to explain the magnitude of the perception of the costs and benefits considered by households.
Finally, the scope for policy intervention aimed at shaping perceived costs and benefits to help the drive towards pro-environmental behaviour is discussed
The Effectiveness of Oxytocin Massage with Breast Care Against Breast Milk Production in Post Sc Mothers
Background: Conditions that affect milk production include the use of medications such as ideas that are used during surgery. Postoperative pain affects the mother to delay breastfeeding and interferes with the lactation reflex, so the mother needs time to recover. Breast milk production affecting by two hormones: the hormone prolactin and the hormone oxytocin. A message from the mother's spine can stimulate the hormone oxytocin. This study aims to clarify the effectiveness of oxytocin and breast care massage on maternal milk production after SC.
Methods This type of quasi-experimental study is only a post-experimental design with a control design. The population of this study were mothers who had SC during March and May 2021. 44 respondents were selected based on random sampling. This study was divided into two groups. Intervention group: mothers after SC received oxytocin massage while control.
Results: The results showed that the average weight gain of babies on day 3 of the oxytocin massage group was 85 grams and 256 grams on day 7 of the massage. While the mean weight gain of children on day 3 in the Maternal Care group was 52 grams, and on day 7, the mean weight gain of children was 155 grams. Based on bivariate test results shows that oxytocin massage has more effect significantly in breast milk production of post-SC mothers (p-value: 0.000).
Conclusion Therefore, in the case of mothers after SC Willing to receive oxytocin massage treatment to promote milk production
On the low detection efficiency of disk water megamasers in Seyfert 2 AGN
Disk megamasers are a unique tool to study active galactic nuclei (AGN)
sub-pc environment, and precisely measure some of their fundamental parameters.
While the majority of disk megamasers are hosted in heavily obscured (i.e.,
Seyfert 2, Sy2) AGN, the converse is not true, and disk megamasers are very
rarely found even in obscured AGN. The very low detection rate of such systems
in Sy2 AGN could be due to the geometry of the maser beaming, which requires a
strict edge-on condition. We explore some other fundamental factors which could
play a role in a volume-limited survey of disk megamasers in Sy2 galaxies, most
importantly the radio luminosity.Comment: 2 pages, 2 figures. To appear in the Proceedings IAU Symposium No.

Typing actors using behavioural types
The actor model of computation assists and disciplines
the development of concurrent programs by forcing
the software engineer to reason about high-level concurrency
abstractions. While this leads to a better handling
of concurrency-related issues, the model itself does not exclude
erratic program behaviours. In this paper we consider
the actor model and investigate a type-based static analysis
to identify actor systems which may behave erraticly during
runtime. We consider the notion of behavioural types
and consider issues related to the nature of the actor model
including non-determinism, multi-party communication, dynamic
actor spawning, non-finite computation and a possibly
changing communication topology, which we contrast with
existing works.peer-reviewe

Il differenziale salariale di genere: teoria e fatti
Questa tesi intende evidenziare l'esistenza di un differenziale salariale di genere nel mercato del lavoro europeo ed intende mostrare quali siano i fenomeni del mercato del lavoro che lo determinano.
Si indaga il fatto che pur a paritĂ di produttivitĂ le donne siano sistematicamente meno retribuite degli uomini.
Si indagano i fattori collegati alla produttivitĂ quali quelli strettamente riferibili al capitale umano come istruzione ed esperienza e altri fattori quali la segregazione occupazionale, settoriale e per tipologia di contratti e la struttura del salario a livello nazionale, facendo riferimento al caso dell'Italia.
Si ricava infine che in Italia come in Europa, il differenziale salariale derivi da una struttura salariale decentrata che allarga il ventaglio retributivo e soprattutto derivi da pratiche del mercato del lavoro che destinano alle donne, segregate in occupazioni, settori e tipologie di contratti tradizionalmente “femminili”, i salari più bassi
The Effect of Supplementary Food in the Form of Moringa Leaf Dry Brownies on the Increasing Weight of Under-Fives with Underweight Status
Background: In 2020, the percentage of underweight children under five in Indonesia is relatively high, which is 6.7% or a total of 779,139 children under five. Wonokerto Village is the village with the highest number of underweight children under five in Turi District. This shows that the problem of under-five malnutrition is still high both in Indonesia and in the regions, even though toddlers are a golden age where the growth process occurs very rapidly and cannot be repeated. Therefore, malnutrition in toddlers needs to be addressed immediately so that growth disorders do not occur. One alternative treatment is with dry brownies of Moringa leaves.
Methods: This study used Pre Experimental designs, One Group Pretest and Posttest with a sample of 34 underweight toddlers who were intervened for 21 days and analyzed their weight gain using the Paired T-Test.
Results: The results showed that there was an increase in underfive weight between before and after being given moringa leaf brownies with a p value of 0.000 < 0.05..
Conclusion: The conclusion is there is an effect of providing additional food in the form of dry brownies of Moringa leaves on increasing body weight in underfives with underweight status.

Simulazione termofluidodinamica di componenti di microturbine per generazione distribuita di energia
Il presente lavoro affronta l’analisi della combustione di idrogeno in una macchina turbogas tradizionale, allo scopo di individuare le prestazioni in termini di emissioni inquinanti.
Inizialmente è fornito un quadro generale relativo alla CFD (Computational Fluid Dynamics), approccio utilizzato per l’analisi numerica del combustore oggetto di studio, e al suo utilizzo, ai suoi limiti, ai modelli implementati nei comuni codici utilizzati nell’industria e nella ricerca.
Sono state eseguite in una prima fase una serie di simulazioni termofluidodinamiche del combustore attraverso il codice di calcolo CFX-5.7 utilizzando parametri e modelli giĂ utilizzati in precedenti lavori nei test numerici con codice FLUENT 6.2 ma con una diversa proposta per la modellazione della combustione, al fine di avere un buon accordo con i valori dati dalla pratica sperimentale.
Successivamente l’analisi numerica è stata effettuata su codice FLUENT 6.2 con l’implementazione di cinetiche chimiche dettagliate per una migliore predizione sul valore degli ossidi di azoto.
Il confronto con le misure sperimentali, ha permesso di giudicare l’idoneità dei modelli e dei parametri gestibili nella modellazione di combustori alimentati ad idrogeno
