Yes / Food Involvement reflects the bond between consumer and food, and serves as a means of expression, identity and social recognition. Yet no existing scales are able to assess the complex psychological nature of Food Involvement. To fill this gap, this study developed and validated a Psychological Food Involvement Scale (PFIS). Data were collected by an online self-report questionnaire, involving 476 Italians aged 20-72 years (M = 48.13, SD = 13.18). The structure and psychometric properties of PFIS were examined through an exploratory and a confirmatory factor analysis, and construct validity was assessed by correlating it with Food Involvement Scale, Food Variety Seeking Scale and the General Health Interest Scale. As a behavioural indicator of validity, food and drink consumption was assessed using the Dietary Habits and Nutrition Beliefs Questionnaire. Factor analysis indicated that the PFIS comprised 19 items grouped in four stable dimensions: Emotional Balance; Self-Realization; Social Affirmation; Social Bonding. People more psychologically involved in food were more interested in healthy eating and more likely to vary their diet. The PFIS discriminated between dietary patterns. Higher PFIS scores were associated with frequent consumption of meat/fish and wholegrains/legumes. Frequent intake of meat/fish and snacks was associated with Social Bonding and meat/fish with Emotional Balance. The PFIS also explained consumption of vegetable drinks and lactose-free milk indicating the symbolic value ascribed to them related to self-expression, acceptance by others, and emotions. This implies potential for the PFIS for use in research to understand food choice and promote healthy eating. / This work was supported by the Fondazione Cariplo and Regione Lombardia within the CRAFT (Cremona Agri-Food Technologies) project ID 2018/2757.

Scale-invariant interest points have found several highly successful applications in computer vision, in particular for image-based matching and recognition. This paper presents a theoretical analysis of the scale selection properties of a generalized framework for detecting interest points from scale-space features presented in Lindeberg (Int. J. Comput. Vis. 2010, under revision) and comprising: an enriched set of differential interest operators at a fixed scale including the Laplacian operator, the determinant of the Hessian, the new Hessian feature strength measures I and II and the rescaled level curve curvature operator, as well as an enriched set of scale selection mechanisms including scale selection based on local extrema over scale, complementary post-smoothing after the computation of non-linear differential invariants and scale selection based on weighted averaging of scale values along feature trajectories over scale. A theoretical analysis of the sensitivity to affine image deformations is presented, and it is shown that the scale estimates obtained from the determinant of the Hessian operator are affine covariant for an anisotropic Gaussian blob model. Among the other purely second-order operators, the Hessian feature strength measure I has the lowest sensitivity to non-uniform scaling transformations, followed by the Laplacian operator and the Hessian feature strength measure II. The predictions from this theoretical analysis agree with experimental results of the repeatability properties of the different interest point detectors under affine and perspective transformations of real image data. A number of less complete results are derived for the level curve curvature operator. / <p>QC 20121003</p> / Image descriptors and scale-space theory for spatial and spatio-temporal recognition

This study explored the relationship between self-development as evidenced in the domain of narcissism and the process of vocational development as evidenced in career values, planning, and decisiveness/self-efficacy. It was suggested that this relationship would be impacted by family birth order and gender. Heinz Kohut's theory of self-psychology was utilized to understand narcissism from both an adaptive and maladaptive, developmental perspective. A review of narcissism and self-development theories was included to provide a comparative and comprehensive approach. Literature indicated that the development of narcissism was influenced by birth order and gender. Additionally, a review of the literature suggested a connection between Kohut's theory of the self and narcissism and aspects of the career development process, such as planning, decision-making, and occupational values. The sample consisted of 346 undergraduate students. Structural Equation Modeling was performed to test causal hypotheses. The major findings of the current study were that superiority (a measure of grandiosity) predicts altruistic career values and career decisiveness. Superiority is a slightly better predictor of altruistic career values than decisiveness. Additionally, goal instability (idealizing) predicts altruistic career values and career decisiveness. Goal instability had a predictive value that was nearly three times stronger for decisiveness. The results indicated that birth order and gender were not moderator variables in examining the relationship between goal instability and superiority. This study provided insight into the relationship between narcissism and the vocational/career development processes. These relationships may be important for career counselors and other related professionals. These findings may encourage counselors to assess and understand a client's narcissistic tendencies and individual representations when assisting in the career development process. A client's values regarding career options, along with his/her associated self-efficacy and ability to make important decisions, appear to be factors to consider when counseling an individual through vocational/career development. Limitations of the study were addressed and directions for further research discussed.

The present study evaluated two hypotheses concerning the comparability of scores of the WISC and WISC-R through correlation of obtained scores on both scales. Forty subjects, representing 10 age levels, constituted the experimental sample. Each subject was administered the WISC, followed in 28 days by the WISC-R. Data analysis revealed significant (.05) correlations between scores on comparable WISC and WISC-R subtests except Arithmetic and Coding. The Verbal, Performance, and Full Scale IQ scores correlated .5468, .5773, and .6240 respectively (p < .01). Conclusions were drawn that caution should be taken in comparison and interpretation of scores on the two scales due to several low correlation coefficients obtained as well as numerous changes between the scales. Further study is recommended.

Perception of scale is important to our activity within a space and to our experience of a landscape. This presents a problem if people cannot predict or convey the scale effects of large structures proposed in a landscape, as has been the case for recent wind turbine proposals in Scotland. To address this problem, this research explored how people perceive scale and scale effects in a landscape. It took wind turbines as an example structure and analysed how different scales of windfarm create different scale effects in different landscapes, as well as how to best assess and communicate these effects. The research applied three methods to address the research questions: Landscape and Visual Impact Assessment (LVIA), which is a standard, structured process applied by professional landscape architects; experiential landscape assessment, which included semi-structured interviews with local people in addition to site assessment; and public attitude and preference study, which included Adaptive Choice-Based Conjoint analysis (ACBC). These different methods allowed the research questions to be explored in different ways, while overlapping in some aspects and providing triangulation. The research findings revealed that our perception of scale and scale effects in a landscape is influenced by numerous attributes and depends on how these are experienced together. Building upon the theoretical background, an important difference between visual scale and spatial scale was highlighted, as well as alternative ways in which scale references are made. Throughout the research, the need for clear communication was emphasised and the findings included identifying the specific words that people use to describe scale effects in the most discriminating way. This research supported other studies in finding that consultation with local people (professionals and the public) was vital to understand in sufficient depth how a landscape was perceived, experienced and valued. In addition, the innovative development of Conjoint Analysis demonstrated how this method can reveal how people judge the relative importance of different attributes that influence landscape and visual effects and, by doing so, offer new possibilities as a tool in landscape research. Building upon the general findings concerning scale, specific findings regarding the scale effects of windfarms included: greater influence of the proximity of a windfarm than size or numbers of wind turbines; greater importance for being in private and/or fixed locations that offer a sense of refuge compared to public locations and/or when moving; the importance of collective effects perceived and experienced by a community; the importance of perceived spatial separation between a viewer and a windfarm (affecting sensitivity to scale effects within open settings); and differences in how people judge the importance of horizontal scale effects compared to vertical scale effects. The research findings contribute to the knowledge and understanding of people’s perception of scale and scale effects in a landscape and they counter some common assumptions and current practice in landscape architecture. They can be applied in practice and policy to help assess scale effects, convey more clearly to people the type of scale effects and how these will affect them, and minimise the adverse scale effects of windfarms through siting and design. The thesis also identifies how to build upon these findings in the future, including recommendations for additional research, new approaches to assessment (including the use of prompt lists) and thresholds for acceptability of scale effects.

Forty-nine Cache Valley residents, between the ages of 18 and 45, who volunteered to participate in an assertion training class were assigned to one of seven groups. Subjects were administered pre- and posttests and a two month follow-up evaluation. Measures included Rotter's Internal-External Locus of Control Scale, the Rathus Assertive Scale, and the Berger Self-Acceptance Scale. The results obtained indicate that self-acceptance and assertiveness changed as a result of assertion training and that these changes were maintained at follow-up. No difference between internals and externals was observed as a result of semi-structured assertion training.

1 Abstract This diploma thesis subjects on rating scales that measure respondent's value of the agreement with given statement. Particularly it focuses on a number of scale points and usage of mid-point and option "Don't know". Due to the fact, there is not an optimal number of points that scale should contain the author focuses on comparing scales of different length. This work includes research that uses four types of the questionnaire to test differences between odd and even scales of different lengths. The thesis shows that share of extreme points is based on scale length. With the use of shorter scales, respondents are more likely to choose extreme points. Based on respondents' answers, the difficulty to choose from scale options is similar in both even and odd scales. Option "Don't know" was mostly chosen by indecisive and poorly-informed respondents when the even scale with above-mentioned option was used. In the case of using an odd scale, the mid-point was chosen also mainly by indecisive respondents, so odd scales should be combined with option "Don't know" for better detection of neutrality. Keywords Rating scale, attitude measurement, odd scale, even scale, mid-point, number of scale points, Web survey, online questionnaire

AbstractBackground: Among the biggest threats to mankind are various environmental problems which have been mainly triggered by human interference with the planet. There have been various ineffective efforts to mitigate these detrimental effects. Therefore, another solution might come in the form of social enterprises tackling the aforesaid environmental problems. However, to increase the impact, they need to scale up. It is therefore of paramount importance to understand their major scale-up challenges as well as proposed solutions to scale up successfully. Along with that, we also scrutinize further scale-up opportunities to uncover the hidden potential of scaling up. Purpose: The purpose of this study is to explore the relationship between social enterprises and their power to tackle environmental problems. We further build on what social enterprises tackling environmental problems must do to mitigate identified scale-up challenges successfully and to be able to seize any scale-up opportunity that comes their way with the main aim of scaling up their positive environmental impact.Method: Ontology – Relativism; Epistemology – Social Constructionism; Strategy –Qualitative, Exploratory; Approach – Inductive; Design – Grounded theory; Data Collection –10 semi-structured interviews; Sampling – Purposive, snowball; Data Analysis – Grounded AnalysisConclusion: Several factors hinder scaling up and solutions to those lie mainly in four key concepts i.e. business idea, value proposition, competency and collaboration. That has been presented in our proposed model (The Hot Air Balloon Model of Scaling Up). We believe that if these four key concepts are well addressed by SEEPs, they are likelier to overcome challenges as well as are in a better position to attract opportunities. Successful scale-up leads to better financial performance along with the overall objective of scaling up the positive environmental impact.

Rural areas of most developing nations are dependent on agriculture. In the most remote areas, sometimes referred to as the "less favored areas" (LFAs), the economic importance of agriculture is paramount. An important obstacle to development in these areas is that agriculture is at the mercy of nature, which may not be particularly friendly. These areas have remained remote due to natural shortcomings causing economic development to occur slower than more advantaged areas elsewhere. Cochabamba Department, in central Bolivia, is home to some of these LFAs. Most Cochabamban producers are located in the "high climatic risk" (CIP-WPA) Andean highlands. Farmers in LFAs surrounding Cochabamba city produce (among other things) potatoes for market and home consumption; the potato is the main source of food and income for most residents. Previous studies and anecdotal evidence have shown that Andean potato farmers may plant upwards of 10 varieties of potatoes on small amounts of land (Brush, 92). Because of the low rates of improved crop variety adoption in many LFA's, efforts are needed to understand farmer objectives and needs with respect to variety characteristics. The goal of this study is to determine how exposure to risk factors impacts potato planting decisions through demand for potato variety characteristics. The main source of data for this project is a survey of 145 farm households implemented during the last quarter of 2007 in 3 communities of Cochabamba. These data were used to estimate an econometric model that evaluated the role of household, regional and variety characteristics in farmer decision making. Decisions about planting each variety were modeled with a Tobit framework and estimated by the Heckman method (as suggested by Cameron and Trivedi), with the impact of individual variety characteristics restricted to be the same for each variety. Several hypotheses were confirmed such as the importance of yield, though many results were different than expected. Blight tolerance was found to be negatively correlated with selection, although most farmers report taking some kind of action to decrease damage from blight. Possible explanations for this negative correlation are discussed in this paper, and strategies for overcoming these obstacles are suggested. / Master of Science
