Purpose – This chapter explores how discourses of obesity as addiction are taken up by weight loss surgery patients and medical and scientific professionals.

Methodology/approach – Based on 14 semistructured interviews, I discuss the ways in which bariatric patients partially account for their presurgical bodies and contemporary struggles with weight loss and regain by referencing food addiction. This work is part of a larger project involving 35 interviews and participant-observation work and therefore these results should thus be considered preliminary.

Findings – I argue that bariatric patients and bariatric professionals portray weight loss surgery as an extraordinary tool that allows the “out of control” to become controllable. However, bariatric patients also emphasize the hard work that is entailed in both losing weight and maintaining a weight loss even after surgery.

Social implications – I suggest that this portrayal, in addition to being an accurate assessment of the potential for regain following weight loss surgery, is a technology of stigma management.

Originality/value – This work contributes to the sociology of the body and medical sociology literatures by illustrating that, within a neoliberal and anti-fat social context, highlighting the hard work involved in weight loss and weight maintenance allows bariatric patients to demonstrate proper subjectivity and thereby reclaim “proper selves” as they work toward a “proper bodies.”

The purpose of this paper is to develop a decision model to help decision makers with selection of the appropriate supplier.

Supplier selection is a multi‐criteria decision‐making process encompassing various tangible and intangible factors. Both risks and benefits of using a vendor in supply chain are identified for inclusion in the evaluation process. Since these factors can be objective and subjective, a hybrid approach that applies to both quantitative and qualitative factors is used in the development of the model. Taguchi loss functions are used to measure performance of each supplier candidate with respect to the risks and benefits. Analytical hierarchy process (AHP) is used to determine the relative importance of these factors to the decision maker. The weighted loss scores are then calculated for each supplier by using the relative importance as the weights. The composite weighted loss scores are used for ranking of the suppliers. The supplier with the smallest loss score is recommended for selection.

Inclusion of both risk and benefit categories in the evaluation process provides a comprehensive decision tool.

The proposed model provides guidelines for supply chain managers to make an informed decision regarding supplier selection.

Combining Taguchi loss function and AHP provides a novel approach for ranking of potential suppliers for outsourcing purposes.

A question of interest is whether online social networks are effective in promoting behavioral changes and weight loss. The purpose of this paper is to examine the contagion effect of an online buddy network on individuals’ self-monitoring behavior.

This study collects data from an online weight-loss community and constructs an online buddy network. This study compares the effects of the network structure of the buddy network and the actor attributes when predicting self-monitoring performance by employing the auto-logistic actor attribute models.

This study confirms the contagion effect on weigh-in behavior in the online buddy network. The contagion effect is significantly predictive when controlling for actor attribute and other network structure effects.

There is limited evidence that one’s weight-related behavior can be affected by online social contacts. This study contributes to the literature on peer influence on health by examining the contagion effect on weight-related behavior between online buddies. The findings can assist in designing peer-based interventions to harness influence from online social contacts for weight loss.

This paper seeks to provide a tool for decision makers to make more informed decisions regarding their outsourcing decisions and selection of the appropriate supplier.

The method uses the Taguchi loss function for the inclusion of intangibles in the evaluation and selection of suppliers. Intangibles are defined as factors that have an impact on the selection of an appropriate supplier but are not easily quantified to be included in the financial evaluation. These intangibles are classified as the benefits and risks of using a supplier to perform the outsourcing function. A decision maker has certain expectations regarding these intangibles and a loss occurs when a supplier's performance does not meet the decision maker's expectations. The Taguchi loss function has been selected as a means of measuring the loss. The decision maker defines the target value and the specification limits for each benefit and risk category. The weighted loss scores are calculated where the weights are the importance ratings assigned to benefit/risk categories by the decision maker. Based on this analysis each supplier will receive a weighted loss score for all the pertinent benefit categories and one weighted loss score for all the risk categories. To achieve a single measure, the aforementioned weighted loss scores are combined to determine a single aggregate loss score for each supplier, which is then used to rank them. The supplier who receives the highest ranking (minimum loss score) will be selected to perform the outsourcing function.

The procedure proposed here can help companies to identify the best supplier to perform an outsourcing function.

The paper presents a phased decision model that begins with economic evaluation and then uses Taguchi functions to measure the impact of intangibles.

Taekwondo (TKD) is a weight‐classified combat sport. Athletes are required to make weight in order to compete in their chosen weight division. However, the weight management strategies that are often employed are frequently at the expense of nutritional health and sporting performance. The purpose of this study is to investigate eating behaviours and general practices used by Taekwondo (TKD) athletes in order to make weight before competition.

A total of 30 male, international and national, TKD athletes (average age: 23.4 years±4.6) were recruited from a known TKD Club in London, UK. Weight management behaviours, beliefs and attitudes were investigated with the use of a specially designed questionnaire.

A total of 87 per cent of the TKD athletes surveyed stated that they would try to reduce body weight before competition to make weight classification and 47 per cent of the athletes reported that, in their effort to reduce weight, they would use a combination of restricting energy and fluid intake and increasing energy expenditure. A total of 80 per cent of the athletes stated that they would attempt to make weight on average six to nine times a year.

Food and fluid restriction in combination with increased energy expenditure were the preferred methods of weight loss employed by TKD athletes in the sample.

The purpose of this paper is to develop a straightforward method to quantify volume and value of postharvest losses in the tomato postharvest value chain in Nepal and estimate the monetary loss shouldered by value chain actors.

The study combines interview data to quantify volume and prices with produce sampling to quantify quality losses, and does this at four nodes of the tomato value chain in Nepal: farmers, collectors, wholesalers, and retailers to estimate volume and value of postharvest losses.

Almost one-fourth of the total tomato harvest weight that enters the value chain is lost before it reaches consumers, and other one-fifth is traded by the value chain actors at reduced price due to quality damage. The total volume of postharvest loss (weight and quality loss) is not the same for all value chain actors and the average monetary loss ranges from 4 percent of gross revenues for farmers to 12 percent for wholesalers.

A standard method to account for both physical weight losses and quality losses of horticultural produce is lacking in estimates of the monetary value of postharvest losses for horticultural crops. Knowing such losses is essential for postharvest technology generation, promotion, and adoption. This study provides a framework that can be adopted and improved in future loss assessment studies for estimating the volume and value of postharvest losses in a horticultural value chain.

The uniqueness of the method used in this study is that it combines interview data to estimate price and volume with produce sampling to quantify quality losses, and does this at four nodes of the value chain: farmers, collectors, wholesalers, and retailers. This method could become a standard approach for assessment of postharvest weight and quality losses and to estimate the monetary value of total postharvest losses in the value chain for horticultural crops.

Patients in secure units are at high risk of obesity because of antipsychotic medication, restrictions on freedom, and poor motivation to eat healthily and exercise. The aim of this paper is to investigate how consultant forensic psychiatrists address weight management, particularly with respect to inpatients.

Based on a review of the literature, a structured questionnaire was developed and piloted locally. After revising the questionnaire, it was sent to all 442 consultant psychiatrists listed by the Royal College of Psychiatrists as having a special interest in forensic psychiatry.

A total of 183 usable questionnaires were returned (response rate 45.9 per cent). Most respondents monitored patients' weight and had some access to a dietitian. Respondents rated a median of 40 per cent of their inpatients as obese. A total of 68.9 per cent said their patients did not have unrestricted access to food. Use of weight loss drugs such as orlistat was infrequent. A few patients had been referred for bariatric surgery but most had been judged unsuitable.

The responses reported in this paper are based on participants' self‐report and have not been confirmed by independent observation. Further research is needed to determine which weight loss measures are effective for psychiatric patients in real‐life situations.

Obesity appears to be common among forensic inpatients despite weight monitoring, dietetic interventions and exercise programmes. Comprehensive and continuing efforts are needed to help patients lose weight and lead healthier lifestyles.

This survey reports on clinicians' views and clinical practice.

This paper aims to analyze the valuation of stock options from the perspective of an employee exhibiting preferences as described by cumulative prospect theory (CPT). In addition, it elaborates on their incentives effect and some implications in terms of design aspects.

The paper draws on the CPT framework to derive a continuous time model of the stock option subjective value using the certainty equivalence principle. Numerical simulations are used in order to analyze the subjective value sensitivity with respect to preferences‐related parameters and to investigate the incentives effect.

Consistent with a growing body of empirical and experimental studies, the model predicts that the employee may overestimate the value of his options in‐excess of their risk‐neutral value. Moreover, for typical setting of preferences parameters around the experimental estimates, and assuming the company is allowed to adjust existing compensation when making new stock option grants, the model predicts that incentives are maximized for strike prices set around the stock price at inception. This finding is consistent with companies’ actual compensation practices. Finally, the model predicts that an executive who is subject to probability weighting may be more prompted than a risk‐neutral executive to act in order to increase the firm's assets volatility.

This research proposes an alternative theoretical framework for the analysis of pay‐to‐performance sensitivity of equity‐based compensation that takes into account a number of prominent patterns of employee behavior that expected utility theory cannot explain. It contributes to recent empirical and theoretical researches that have advanced CPT framework as a promising candidate for the analysis of equity‐based compensation contracts.

Weight loss on an 800 k/cl ketogenic diet is faster than that on a mixed diet due to extra water loss. In each regimen fat loss is equal and similar to that during total starvation in which much greater protein losses occur.

The purpose of this paper is to examine the effect of the intensive lifestyle modification program on weight and metabolic syndrome risk reduction in rural obese women who have no underlying non-communicable diseases in Thailand.

A randomized controlled trial was conducted. In total, 60 healthy obese women aged 30-50 years were recruited and randomly assigned to either the intervention (n=30) or control (n=30) group after health screening. Tailored nutritional counseling, health education and exercise training were included in the lifestyle modification program. Behavioral modification techniques were also incorporated. The intervention was conducted weekly for the first eight weeks, then biweekly until week 16.

The student’s t-test was used to compare mean difference between groups. The total weight loss in the intervention group (n=29) was significantly higher, 7.6±2.9 kg, compared with the control group (n=30) who lost 0.7±1.4 kg (p<0.001). The intervention group lost weight 10.2 percent from baseline which was significantly higher than that in the control group (p<0.001). Systolic and diastolic blood pressures, fasting blood sugar, and waist circumference were significantly improved. Triglyceride levels slightly improved while high density lipoprotein cholesterol was slightly lowered. The intervention group showed a statistical reduction in abnormal components of metabolic syndrome compared with the control group, with the relative risk=0.24, 95% confidence interval=0.072-0.791, and p=0.018.

Compatibility of the program activities conducted by a health professional who had achieved healthy weight loss and accepted as a role model was a key to achieving effective weight loss and metabolic syndrome risk reduction in obese women in rural areas. The program should be integrated into the conventional practice of health care centers.
