If You Provide It, Will They Read It? The Effect of Information on Choices

This paper investigates the effect of information on respondent's choices in an internet survey for measuring the value of water quality improvements in Deckers Creek (DC) watershed in Monongalia and Peterson Counties of West Virginia, USA. A multiattribute, choice experiment and multinomial logit (MNL) models are used in estimating the marginal utilities of restoring the three attributes of DC: aquatic life, swimming safety, and scenic quality. Response times serve as proxy variables regarding whether respondents read or did not read all the information provided in the survey. Response times fell quickly, but then tapered off as they progressed through the various sections of the survey. Results show that the estimated coefficients of subsamples, read and did not read all the information, were statistically different from each other. Based on log likelihood tests of MNL models, two subsamples of the survey population (read and did not read all information) were found to be from different populations. Estimates of marginal utilities reveal that respondents value aquatic life restoration the highest, followed by scenic quality restoration. Average compensating variation estimates for full restoration of the aquatic life and scenic quality attributes are $9 and$ 6 per month per household, respectively, when the subsamples are pooled. However, the individual subsamples resulted in $5 per month for aquatic life and$3 per month for scenic quality for respondents that read the information, while respondents that did not read the information resulted in statistically higher estimates of $16 and$12, respectively. While respondents' motives for not reading the resource information provided is uncertain, results show their values for watershed restoration are substantially higher than respondents that read the information.Demand and Price Analysis,

La Casa di correzione di Firenze (1782-1794). Disciplinamento di “discoli”, “oziosi” e “donne di mala vita”.

La Casa di correzione, istituita da Pietro Leopoldo nella Fortezza da Basso a Firenze nel 1782, fu originariamente pensata come strumento di ausilio ai genitori nell'educazione dei figli, che potevano fare richiesta di iniviarveli quando "discoli", "vagabondi", "oziosi" o libertine se femmine. La Casa di correzione doveva correggerli tramite una reclusione basata sul binomio preghiera-lavoro. Creata a seguito della riforma del 26 maggio 1777, essa fu anche, però, uno strumento di giustizia "economica" nelle mani delle rinnovate forze di polizia, per il mantenimento della quiete pubblica e la prevenzione dei delitti, nella convinzione che "il pronto riparo alli sconcerti piccoli previene i più grandi". Fu il figlio di Pietro Leopoldo, Ferdinando III, a porre fine a questo esperimento nel 1794, animato da una visione forse più garantista della giustizia

Social Identity, Mental Toughness, and Behavioural Intentions as Antecedents of Overuse Injury Pain in Physical Activity Contexts

Psychological factors specific to overuse injury pain in physical activity contexts were explored within a social identity theoretical framework. Study 1 involved development of a method for designating overuse injury pain occurrence of hikers (N = 751), along with exploration of relationships between psychological measures, overuse injury pain occurrence, and effort levels. The findings of this cross-sectional, mixed-methods investigation revealed that social identification, social identity content, and mental toughness differentiated hikers who incurred overuse injury pain or selected a higher-effort behaviour from those who did not. From qualitative analysis, several social identity constructs (i.e., group member’s presence, in-group status, social creativity, additional social identity content) emerged as contributors to overuse injury occurrence. The focus of Study 2 was a prospective examination of the aforementioned psychological factors in relation to overuse injury severity of hikers (N = 283). Additionally, the Test of Intentions to Reduce Effort (TIRE) was developed to identify individuals with susceptibility to higher overuse injury severity. Results provided evidence of factorial, construct, and predictive validity of TIRE factor scores. TIRE factors and social identity content significantly predicted higher severity of hikers’ overuse injury pain. Mental toughness scores moderated the relationship between social identification and overuse injury severity. Study 3 consisted of a qualitative examination of social identity mechanisms of overuse injury pain in a physical activity context, CrossFit®, involving the presence of group leaders, and in which group members view each other. Findings revealed mechanisms pertaining to social identity content, in-group status, and social threats. Overall, the findings support a new means for assessing overuse injury occurrence and susceptibility to higher overuse injury severity, whilst demonstrating the potential applicability of social identity theory to the study of overuse injury. Knowledge gained may ultimately aid development of interventions to reduce overuse injury occurrence and severity of physical activity participants

Bandwidth selection for kernel estimation in mixed multi-dimensional spaces

Kernel estimation techniques, such as mean shift, suffer from one major drawback: the kernel bandwidth selection. The bandwidth can be fixed for all the data set or can vary at each points. Automatic bandwidth selection becomes a real challenge in case of multidimensional heterogeneous features. This paper presents a solution to this problem. It is an extension of \cite{Comaniciu03a} which was based on the fundamental property of normal distributions regarding the bias of the normalized density gradient. The selection is done iteratively for each type of features, by looking for the stability of local bandwidth estimates across a predefined range of bandwidths. A pseudo balloon mean shift filtering and partitioning are introduced. The validity of the method is demonstrated in the context of color image segmentation based on a 5-dimensional space

TANTANGAN PRODUKSI PERTANIAN TERHADAP KELANGKAAN AIR DAN KETERSEDIAAN LAHAN PERTANIAN DI MASA DEPAN

This research aims to analyze the challenges of future agricultural production in terms of water scarcity and the availability of agricultural land while exploring strategies that can be applied to address these challenges. The study employs a systematic literature review approach with a sample of 30 journals from various developed and developing countries. These journals span publication years from 2000 to 2021. Further investigation by reading the abstracts of each selected journal was conducted to ensure their relevance to the research objectives. The research findings indicate that water scarcity and the availability of agricultural land are significant factors influencing the sustainability of agricultural production. The absence of these inputs can have a substantial impact on meeting global demand. Factors such as extreme climate change, land conversion, population growth, and increased demand for agricultural products contribute to water scarcity and the limited availability of agricultural land. Strategies employed to address these issues involve a combination of policy measures and environmental prevention and adaptation strategies, such as wastewater and saline water management for irrigation, the use of superior crop varieties, changes in crop intensity, improved weather forecasting for farmers, and crop diversification. Moreover, to combat the shrinking availability of agricultural land, several strategies can be implemented, including optimizing land-use intensity, increasing the crop yield index, and formulating policies related to land-use conversion.
