Eigenvalues and completeness for regular and simply irregular two-point differential operators
No full textAugust 29, 2006.In this monograph the author develops the spectral theory for an nth order two-point differential operator L in the Hilbert space L2[0,1], where L is determined by an nth order formal differential operator ℓ having variable coefficients and by n linearly independent boundary values B1,…,Bn. Using the Birkhoff approximate solutions of the differential equation (ρnI−ℓ)u=0, the differential operator L is classified as belonging to one of three possible classes: regular, simply irregular, or degenerate irregular. For the regular and simply irregular classes, the author develops asymptotic expansions of solutions of the differential equation (ρnI−ℓ)u=0, constructs the characteristic determinant and Green's function, characterizes the eigenvalues and the corresponding algebraic multiplicities and ascents, and shows that the generalized eigenfunctions of L are complete in L2[0,1]. He also gives examples of degenerate irregular differential operators illustrating some of the unusual features of this class.1. Introduction -- 2. Birkhoff approximate solutions -- 3.

Optimizing Parcel Locker Locations with Pricing Decisions in Last-Mile Delivery
No full text22nd International Symposium for Production Research, ISPR 2022 -- 6 October 2022 through 8 October 2022 -- -- 291539The parcel locker is a new last-mile delivery concept that provides outdoor delivery of commercial goods. In recent years, determining the parcel locker locations has become critical in the literature to provide an effective locker service to the customer. Accordingly, this study aims to optimize the parcel locker locations with effective pricing decisions for the locker service. We use a price-response function to determine the price of the locker service in the customer layers. We generate new benchmark problems to evaluate the performance of the mathematical modeling approach. The computational results indicate that the price-response function is effective in determining the price of the locker service, and the proposed mathematical model, having introduced customer layers, gives promising results for future studies on combining the optimization of parcel locker location decisions and pricing widely applied in revenue management practices. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG
A hybrid Bayesian BWM and Pythagorean fuzzy WASPAS-based decision-making framework for parcel locker location selection problem
No full textOne of the main causes of the significant commercial vehicle traffic in the city region is last-mile deliveries. Parcel lockers, which are one of the easiest and most environmentally friendly solutions for last-mile delivery, are one of the most studied subjects recently. The parcel locker ensures consumer privacy while being quick and efficient. Its full-time service can effectively address the issue of student and office worker pickup. In this paper, the location of a parcel locker intended to be established in the most convenient location in Beşiktaş district of İstanbul, Turkey has been determined. This problem can be solved using a multi-criteria decision-making (MCDM) structure due to the availability of numerous aspects that must be considered while choosing the optimum location. Additionally, the benefit of fuzzy logic is employed to translate expert opinions into mathematical expressions and incorporate them into decision-making processes. To choose the ideal location for the parcel locker, a novel model integrating the Bayesian Best Worst Method (B-BWM) and Pythagorean fuzzy Weighted Aggregated Sum Product Assessment (PF-WASPAS) approaches is proposed for the first time in the literature. Additionally, a sensitivity analysis is conducted to evaluate the model’s robustness. As a consequence, the suggested model effectively identifies the best location for a parcel locker in Istanbul
Implementation of Receiver Preferences in a Parcel Locker Network for Last Mile Deliveries
No full textWith the current growth of e-commerce, couriers need to serve a bigger demand and it is often the case that receivers are not at the location when their parcel is delivered. The use of parcel lockers is seen as a good option for improving the problem of failed deliveries. However, implementing a parcel locker network has an impact on both couriers and receivers, which still prevents couriers from directly adopting this technology. The aim of this research is to develop a new tool that helps couriers analyse the impact of using a parcel locker network taking also into account receiver preferences to pick up parcels from lockers. An optimization model is combined with a choice behaviour model to determine the trade-offs between delivering to parcel lockers or to end-users, in terms of service level and total transportation costs. In order to solve this model for large instances, an Adaptive Large Neighbourhood Search algorithm has been adapted with operators and criteria specific for the problem presented. Computational experiments were carried in a set of the Solomon instances and show that the problem can be solved efficiently with the proposed algorithm. Moreover, the algorithm was applied in a small delivery area in Rotterdam, showing the sensitivity of the model to the preferences of receivers in the area.Transport, Infrastructure and Logistic
What we talk about when we talk about the locker room: Women sportswriters' stories
No full textEvery week, hundreds of women sportswriters enter male sports locker rooms without incident as they gather post-game quotes from players and coaches. Locker room interactions comprise less than 10 per cent of most women sportswriters' jobs yet they have profoundly impacted women writers' lives.Based on in-depth interviews with 27 female sportswriters and a close reading of more than 100 newspaper and magazine articles, this study explores how locker room interactions have affected women sportswriters since the late 1960s. Using Norman Denzin's (1989) interpretive interactionist approach, I attempted to understand women sportswriters' worlds from within--through their eyes, using their language and frameworks for understanding."My analysis revealed that women sportswriters' lives are far more dynamic and diverse than is apparent from media representations. Changes in women sportswriters' understandings of the locker room and their experiences within it have been marked by ruptures: public moments that have catapulted writers into new ways of seeing. Three key moments mark shifts in understanding from seeing the locker room first as inaccessible, then as a male space in which athletes' definitions dominate, and recently as a public space in which women writers' and athletes' definitions hold equal weight. The first rupture was Sports Illustrated writer Melissa Ludtke's successful 1978 lawsuit which forced the New York Yankees to provide her with equal access to athletes. The second involved the 1990 media ""feeding frenzy"" over the locker room harassment of Boston Herald reporter Lisa Olson by naked New England Patriots players, and the third was a result of the 1991 public debate around Anita Hill's testimony against Supreme Court nominee Clarence Thomas."Women sportswriters draw upon a variety of resources to categorize their interactions with male sports personnel, such as cultural context, personal knowledge of the individuals involved, past experience, and the specific characteristics of the encounter, as well as their understandings of the space of the locker room. Behaviors that objectively appear similar, such as players undressing in front of a woman sportswriter, have been categorized by women in each of the four major categories which emerged from my analysis (supportive, professional, teasing/testing or hostile). Hostile interactions cause the most emotional trauma and constitute the majority of stories women tell about the locker room. In hostile interactions, gender relations are revealed in particularly powerful ways, as males reject female sportswriters' professional selves and choose to attack them based solely on gender. Hostile interactions cause epiphanic, or turning point, moments in writers' lives, and may lead to gradual or abrupt changes in careers. Despite their ongoing discomfort, however, women writers support the dominant sports journalism belief that locker room access is vital to good reporting.Finally, my analysis revealed a huge contrast in women sportswriters' understandings of themselves and those of the public and male sports personnel. Many men appear to believe women writers are sexually aroused by locker room interactions and driven by sexual desires for male athletes. Women writers universally reject this interpretation and many appear mystified at how males could imagine a locker room as sexually appealing.Made available in DSpace on 2011-05-07T14:00:24Z (GMT).

Private consumers preferences, awareness and ratings about parcel locker station services on the example of DPD Estonia
No full textKäesoleva lõputöö eesmärgiks oli välja selgitada ertarbijatest pakiautomaadi teenusekasutajate eelistused, valikukriiteriumid, teadlikkus ning tarbijate kogemuse hinnangud teenusele. Antud teema on DPD Eesti jaoks aktuaalne, kuna ettevõtte sisenes pakiautomaatide turule ning soovitakse tõsta oma turuosa. Teenuse arendamisel on vaja aga rohkem teadvustada ja arvestada eratarbijatest teenusekasutajate soovidega. Antud lõputöö raames viidi läbi kvantitatiivne uuring, kus uuriti pakiautomaatide teenusekasutajatelt nende eelistusi, valikukriteeriumeid, teadlikkust ja hinnanguid kogetud teenusele. Lähtuvalt antud töö eesmärgist, viis autor läbi küsitluse pakiautomaatide teenusekasutajate hulgas. Eesmärgi täitmiseks püstitas autor järgmised uurimisküsimused: • Millised on teenusekasutajate eelistused pakiautomaatide teenuste valikul? • Millised on teenusekasutajate valikukriteeriumid erievate teenuste osas? • Milline on teenusekasutajate teadlikkus erinevate pakiautomaatide teenusepakkujate osas? • Milline on teenusekasutajate hinnang erinevate teenusepakkujate osas? Autor analüüsib küsitluse tulemusi läbi erinevate klastrite. Esimeses analüüsis jaotati kõik teenusekasutajad kaheks sootunnuse järgi ning vaadeldi eraldi meessoost ja naissoost kliente. Teises analüüsis rühmitati kliendid vanuse järgi noorteks, keskealisteks ja eakamatest. Kolmandas ja viimases analüüsis jaotati teenusetarbijad rühmadesse vastavalt sellele, kas nad on sagedased, aegajalt või harva pakiautomaadi teenusekasutajad. Analüüsist selgus, et meessoost ja naissoost tarbijad ei erinenud oluliselt oma valikutes ja hinnangutes. Samas vanuse või teenusekasutamise tiheduse järgi on klientidel erinevad eelistused, teadlikkus ja hinnangud pakiautomaadi teenusele. Antud lõputöö tulemuste põhjal võib öelda, et Eesti tarbijad peavad pakiautomaatide ja pakipunktide teenuseid kasutades kõige olulisemateks kriteeriumiteks - teenusepakkuja tarnelubadusest kinni pidamist, paki saabumisest teavitustööd, tarne kiirust ning teenusepakkuja töökvaliteeti. Kõige vähem oluliseks valikukriteeriumiteks osutus klienditeenindus, tarne ümbersuunamine ja sama päeva tarne. Uurigu tulemuste analüüsimisel selgus, et teenusekasutajate teadlikkus on DPD Eesti konkurentide osas väga kõrge (98-99,5%) samas kui DPD Pickup pakiautomaadi osas 60,5% ja pakipoe osas vaid 48%. Veelgi suurem vahe on teenusekasutajate kogemuse osas, kus konkurentide teenuseid on kasutanud 75,5-84,5% klientidest, samas kui DPD Pickup pakiautomaati on kasutanud 13,5% ja pakipoodi vaid 12% küsitluses osalenutest. Lõputöö tulemustest selgus ka tarbijate hinnang erinevatele teenusepakkujatele. Hindamine toimus palli skaalal, kus 5-väga rahul. Kõige kõrgema hinnangu sai Itella Smartposti pakiautomaadi teenus, mida hindasid erinevad kliendigrupid 5 palli skaalal 4,4-4,5 vääriliseks. Omniva pakiautomaadi teenusele anti hindeks 4,1-4,2. DPD Pickup pakiautomaadi teenust hinnati erinevate kliendigruppide poolt vahemikus 3,9-4,5 ning DPD Pickup pakipoe teenust 3,7-4,4. Lõputöö autor tegi antud töö tulemuste põhjal DPD Eestile kokku üheksa ettepanekut. Ettevõte juhtkond lubas autori poolt esitatud ettepanekuid arvesse võtta ning seega on lõputööl ka praktiline väärtus. Rakendades töös tooduid ettepanekuid on ettevõttel parem võimalus saavutada püstitatud eesmärgid saada seitsme aastaga pakiautomaaditeenuse turuliidriks Eestis.The subject of this thesis is “Private consumers preferences, awareness and ratings about parcel locker station services on the example of DPD Estonia”. The subject is appropriate because the company has entered the market of parcel locker station services and they have an ambitious plan to raise their market share. To achieve the goal, the company needs to understand and to take more into account about the needs and wishes from the private consumers. This thesis was carried out a quantitative study. The focus was to explore private consumers about their references, selection criteria’s as well as awareness and ratings about parcel locker station services. Given the purpose of this thesis, the author conducted a survey among users of parcel locker stations. To reach the goals set for the author, the following research questions were used: • What are the consumer’s preferences in the selection of parcel station locker services? • What are the selection criteria’s of the consumers about different services? • What is the service users awareness about various parcel station locker providers? • What is the assessment of the various users of the service providers? The survey results were analyzed through different clusters. In the first analysis the author separated male and female consumers. In the second analysis consumers were grouped according to age – the young, middle aged and older. In the third analysis the consumers were divided according to whether they are continuous, occasional or rare parcel station service users. The analysis showed that the male and female consumers did not differ significantly in their choices and assessments. However, dividing consumers by age or frequency, the results differ significantly and the consumer segments are having different preferences, awareness and ratings to parcel locker station services. Based on the results of this thesis it shows that Estonian consumers value the most important factors in the parcel locker station services as following: • reliable and accurate information about arrival of the package, • keeping the delivery promise, • delivery speed, • quality of work. Results of the survey also showed that for consumers less valuable factors were customer service, same-day delivery and redirected delivery. Analysis of the results revealed that the service users awareness was very good among competitors (98-99,5%) but was as low as 60,5% among DPD Pickup parcel locker stations and 48% among DPD Pickup parcel shops. The difference between the competitors and DPD Estonia is even bigger when we look at how many consumers, by this study, have used competitor services (75,5-84,5% of all consumers) and in the case of DPD Pickup parcel locker stations it was only 13,5% and in the case of DPD Pickup parcel shop the result was 12%. Results of the thesis also showed the consumers assessment on various service providers. The highest result was given to Itella Smartposti parcel locker station service, where all consumers groups total value was in 4,4-4,5 in the scale of 5 to 1. Omniva parcel locker station service was valued 4,1-4,2 and DPD Pickup parcel locker service was valued by all consumers groups in the range of 3,9-4,5 as well as DPD parcel shop in the range of 3,7-4,4. Author made to the DPD Estonia nine different proposals to reach the goals set. The management of DPD Estonia promised to take into account the proposals submitted by the author and therefore final thesis has practical value of the work. Applying those proposals, the company has a better chance to achieve the goals set and to become the market leader in the parcel locker station services
Qualitative evaluation of the Mentors in Violence Prevention pilot in Scottish high schools
No full textObjective The Mentors in Violence Prevention (MVP) program originated in the US and adopts a bystander approach to gender-based violence prevention by harnessing group processes using a peer-learning model. This paper presents the first qualitative evaluation, within a European context, of a pilot application of MVP within a Scottish High School setting. Method The evaluation comprises a series of interviews and focus groups with school staff, and pupils (‘mentors’ and ‘mentees’) at three participating schools. The study’s research purposes are to explore: 1. Experiences of participating in MVP; 2. Participants’ perceived impact of MVP (with regards attitudinal and behavioral change with a particular emphasis upon social norms); and 3. Participants’ opinions on the relevance and sustainability of MVP. Results All three categories of participant reported generally positive experiences of MVP in terms of recruitment, training, and implementation. The peer-learning model was particularly useful in engaging mentees, and facilitating support networks outside the classroom. Moreover, positive attitudinal and behavioral change regarding gender-based violence was reported by all three participant categories, but was particularly prevalent amongst mentors. However, participants highlighted the importance of ensuring MVP is culturally relevant, and the need for integration into school life to ensure its sustainability. Conclusions An initial qualitative analysis of MVP within Scottish High Schools suggests the peer-learning program was experienced positively, with self-reported impact on gender-based violence attitudes and behaviors (including bystander intervention). A number of recommendations have been made to inform future implementation of MVP, and the need for robust, on-going evaluation.Peer reviewe
