In this study, we investigate several facets of a due-date quotation problem and develop a model considering jointly due-date quotation, order acceptance and base-stock decisions in a hybrid make-to-stock (MTS) / make-to-order (MTO) and multi-class system with lead time sensitive Poisson demand and exponentially distributed service times. We seek to maximize profit considering lateness penalties and holding costs in the model. We consider three alternative due-date quotation policies each having different properties in terms of due-date flexibility as well as the utilization of state information. In order to evaluate the value of due-date flexibility as well as state information, the performances of the optimal policy and alternative policies are evaluated for various performance measures under different operating conditions. We also discuss the benefit of joint pooling of inventory and capacity under optimal policy and an accept-all policy.

During the last decade, social media has had a great impact on the way we communicate. It has also expanded our awareness of the world.! However it has become harder for the lay person to find news, because of too many conflicting interests in the mass media industry on one hand, and simply too much free information available on the other! This report documents my study of how social media has affected the way we collect, consume and share news. I describe how democratization of information has made some things easy, but some other things hard - filtering data to find meaningful content has become harder! My studies were targeted mainly at people younger than 30, and mainly in India, and much of its design is informed by problems characteristic to the Indian context. So while I do not explicitly target my end result at the Indian market, a news network by its very nature needs to be global, and this process reflects that.! I go on to use Design Methods including Brainstorming, Participatory Workshops and Service Design theory to arrive at a product that aims to provide people a way to stay up to date with meaningful and relevant news. ! I propose a social network for individuals to exchange news with each other. I try to understand what makes some pieces of information more important than others, and how a network can self filter information so that participants can get high quality content.! In the final result, I describe the framework of this network and how people would contribute to it and consume from it.

Efficient reuse of waste water requires removal of micro-pollutants from waste water streams by affordable and sustainable methods. Activated carbon is considered a powerful adsorbent due to its high surface area and low cost of treatment, compared to other expensive methods such as membrane filtration. Producing activated carbon with larger mesoporosity (>2nm) is of particular interest in industry in the removal of larger molecular sized pollutants. This study reports the synthesis of mesoporous activated carbons from a nonsoluble biomass precursor (date-pits) along with chemical activation using ZnCl2. Thus, produced activated carbon showed high surface area and large mesopore volume up to 1571 m2/g and 2.00 cm3/g respectively. In addition, the pore size of the product was as high as 9.30 nm. As a method of verification, HRTEM (Highresolution transmission electron microscopy) was used to directly authenticate the pore size of the synthesized activated carbons. Tannic acid and atrazine were used as model waste water pollutants and the adsorption capability of the produced activated carbon for these pollutants were evaluated and compared to a commercial mesoporous carbon: G60 from Norit. The results showed that the sorption capacity of produced activated carbon for tannic acid was 2 times that of G60 while the sorption capacity of produced activated carbon for atrazine was lower than that of G60. The activated carbon was also evaluated for adsorption of real secondary effluent municipal wastewater and the results suggest that the produced activated carbon was able to sorb a greater amount of biopolymers than G60. These results demonstrate that the thus-produced activated carbon may be a promising sorbent for waste water treatment.

2 pp. / Until the introduction of semi-dwarf wheat in the late 1960s, wheat varieties were typically one and a half to two times their current height. Most heirloom, traditional, or landrace varieties are considered standard-height wheat (e.g. Sonoran white); in general they are adapted to lower-input conditions, and cannot tolerate high-fertility environments without lodging. Lodging reduces grain yield, delays harvest, and increases harvesting costs. Standard-height wheat needs to be grown at a lower plant density and with less nitrogen and irrigation water than semi-dwarfs in order to prevent lodging, optimize yield, and make the most efficient use of resources.

Midlife adults who have divorced or never married represent a growing demographic in North America. Despite this fact, little research has examined the dating and sexual behaviours of these individuals. Research has instead focused on the dating and sexual lives of young adults, particularly undergraduate students. The current research program examined young (aged 18-24 years) and midlife (aged 35-54 years) single (or recently single) heterosexual North American adults’ typical first date scripts and their retrospective perceptions of their first date experiences. More specifically, Study 1 examined young and midlife adults’ typical first date scripts. Participants were asked to list at least 20 actions that a woman would typically perform on a first date with someone new, from the beginning of the date to its end, putting the actions in the order in which they would occur. Participants were then instructed to carry out the task a second time, focusing on the actions that a man would typically perform on a first date with someone new. Study 2 examined young and midlife adults’ retrospective accounts of their actual first date scripts, as well as their actual first date sexual behaviour. Participants were asked to list at least 20 actions that they performed on their most recent first date, from the beginning of the date to its end, putting them in the order in which they occurred. They were also asked to complete a revised Guttman scale of sexual behaviours, checking off from a list the behaviours that occurred on their most recent first date. Across both studies, analyses revealed three key patterns with respect to gender roles. First, contrary to expectations, young adults tended to be more traditional than midlife adults with respect to first dates. Second, midlife adult women tended to be less traditional than expected with respect to first dates. Lastly, in keeping with expectations, women were depicted as taking a passive role and men were depicted as taking a more active role in the scripts. Implications of the findings and recommendations for future research follow.

Background: Victims of sexual assault have been reported to blame themselves for the incident. They see themselves as having somehow contributed to the situation. Self-blame associated with a sexual assault is argued to be socially constructed, influenced by culture’s perception of sexual crimes. A specific behaviour that appears to contribute to victim’s self-blame is alcohol use during the sexual assault incident. Approximately half of sexual assaults are associated with alcohol consumption by one or both parties. Victims who consume alcohol during the incident are more likely to blame themselves for the event. Self-blame has been linked to a decreased likelihood of reporting a sexual assault to authorities, as victims predict that others will disapprove their behaviour and blame them for their victimization. Limited research has been conducted on attribution of blame to the female victims who have been under the influence of alcohol during the sexual assault incident. Objective: To examine the association between a female’s level of intoxication and the level of blame attributed to her, and how this is modified by initiation and severity of the event, in a hypothetical date-rape scenario. Methods: Secondary data analyses of 1004 quantitative telephone surveys completed in Sweden by randomly selected young adults aged 16-24. Date-rape vignettes were used and male’s and female’s levels of intoxication, severity of the outcome and the person initiating the sexual contact (perpetrator or victim) were manipulated. The depended variable was the amount of blame assigned to the female in the hypothetical date-rape scenario. The attribution of blame to the female was analysed using factorial ANOVA in SAS. Results: For female respondents, the level of blame attributed to the female in the hypothetical date-rape scenario depended on a three-way interaction between the inebriation level, initiation, and severity, controlling for female respondents’ living situation in the last 12 months, their frequency of drinking five or more drinks in the past 12 months, and their expectancy that ‘alcohol makes people more sexual’. For male respondents, however, the level of blame attributed only depended on the severity of the situation, controlling for male respondents’ mean number of standard drinks to feel the effects of alcohol and their attitude that ‘alcohol lessons control’. Conclusion: The inebriation level of the female in the date-rape scenario has been illustrated to impact the amount of blame attributed to her, by female respondents. This has implications for reporting rates of sexual crimes, and thus should be addressed by future policies and programs.
