Authors: Lindquist Ruth , VanWormer Arin , Lindgren Bruce , MacMahon Kathleen , Robiner William , Finkelstein Stanley 
Published: July 2017

Background The emergence and subsequent integration of new technologies precipitate changes in roles and work lives of nurses. The nurses' work with home monitoring technologies within a spirometry-based program that transmits pulmonary function data after lung transplantation has characteristics that are distinct from other types of direct patient care. Nurses' changing roles in such programs after transplantation have not been well described. Objective To describe a time-motion study of 2 research nurses in the context of a home-spirometry study to monitor patients' pulmonary status after lung transplantation. Method A detailed list of research nurses' 67 routine work-related activities was developed and validated to monitor and record activities of research home monitoring nurses. Two weeks of observations were completed; recordings of a second observer established reliability of observations. Results In 48.8 hours of observation, 610 tasks related to monitoring of 45 patients were recorded. Task time ranged from brief seconds (eg, data review) to 39 minutes (eg, clinic visits). Between-observer intraclass correlation ( r=0.96) reflected high agreement in observations of the duration of activities. Agreement for category of activity was strong (κ = 0.82), with high levels of agreement (96%). Computer tasks were the most frequent (118 tasks/week) and most time-intensive activities. Nurses' face-to-face interactions with health professionals were equally time intensive (both 267 minutes/week), but not as frequent. Data review tasks were the second most frequent (49/week), although less time-intensive (47 minutes/week). Conclusion Findings reveal patterns of effort and time expenditure in nurses' evolving roles in home monitoring of the health status of patients after lung transplantation. These findings highlight the centrality and importance of well-developed data management, computer skills, and interprofessional communication skills of nurses who perform responsibilities in this emerging role in transplantation. Efforts to streamline computerized information access, as through integrated information systems, and methods to enhance efficiency in connecting with patients in the clinic may free up time for nurses to engage in other activities of direct benefit to patients. Strategies to supplement face-to-face meetings among professionals with electronic modalities may reduce the time spent meeting, while maintaining or enhancing communication.

Background: The use of lasers has become increasingly common in the field of medicine and dentistry, and there is a growing need for a deeper understanding of the procedure and its effects on tissue. The aim of this study was to compare the erbium-doped yttrium aluminium garnet (Er:YAG) laser and conventional drilling techniques, by observing the effects on trabecular bone microarchitecture and the extent of thermal and mechanical damage. Methods: Ovine femoral heads were employed to mimic maxillofacial trabecular bone, and cylindrical osteotomies were generated to mimic implant bed preparation. Various laser parameters were tested, as well as a conventional dental drilling technique. The specimens were then subjected to micro-computed tomographic (μCT) histomorphometic analysis and histology. Results: Herein, we demonstrate that mCT measurements of trabecular porosity provide quantitative evidence that laser-mediated cutting preserves the trabecular architecture and reduces thermal and mechanical damage at the margins of the cut. We confirmed these observations with histological studies. In contrast with laser-mediated cutting, conventional drilling resulted in trabecular collapse, reduction of porosity at the margin of the cut and histological signs of thermal damage. Conclusions: This study has demonstrated, for the first time, that mCT and quantification of porosity at the margin of the cut provides a quantitative insight into damage caused by bone cutting techniques. We further show that with laser-mediated cutting, the marrow remains exposed to the margins of the cut, facilitating cellular infiltration and likely accelerating healing. However, with drilling, trabecular collapse and thermal damage is likely to delay healing by restricting the passage of cells to the site of injury and causing localized cell death.
Personal and Social Usage: The Origins of Active Customers and Ways to Keep Them Engaged
Authors: Lee Clarence , Ofek Elie , Steenburgh Thomas J. 
Published: July 2017

We study how digital service firms can develop an active customer base, focusing on two questions. First, how does the way that customers use the service postadoption to meet their own needs (personal usage) and to interact with one another (social usage) vary across customer acquisition methods? Second, how do firm-to-customer and customer-to-customer communications promote different types of usage? We study these questions using two data sets and by developing a multivariate hierarchical Poisson hidden Markov model (HMM), which fits the data significantly better than univariate and latent class approaches. We indeed find that postadoption behavior varies depending on customer acquisition method and dynamic states. At the total usage level, in one context (an annotation and note-taking service), customers who heard about the service through search and mass-invite exhibited significantly higher usage compared to those who joined through word of mouth (WOM), whereas in another context (a cloud-based file storage service), customers who joined through WOM referrals tended to exhibit higher usage. Yet, examining how routes of adoption relate to specific types of behavior, personal versus social usages, reveals a more nuanced picture. Furthermore, in both contexts, communications postadoption influenced engagement, albeit in different ways. Firm-to-customer communications, through company posts to Twitter and blog entries, had varying effects on customer behavior and in some cases led to lower personal and/or social usage; however, customer-to-customer communications tended to increase personal-use engagement across latent states and in both data sets. The findings suggest that firms offering digital services should pay attention to how the mode of customer acquisition is related to subsequent usage intensity, accounting for both personal and social activity, and encourage customers to interact with each other postadoption.

Competitive Strategies for Brick-and-Mortar Stores to Counter “Showrooming”
Authors: Mehra Amit , Kumar Subodha , Raju Jagmohan S. 
Published: July 2017

Customers often evaluate products at brick-and-mortar stores to identify their “best-fit” product but buy it for a lower price at a competing online retailer. This free-riding behavior by customers is referred to as “showrooming,” and we show that this is detrimental to the profits of the brick-and-mortar stores. We first analyze price matching as a short-term strategy to counter showrooming. Price matching allows customers to purchase a product from the store for less than the store’s posted price, so one would expect the price matching strategy to be less effective as the fraction of customers who seek the matching increases. However, our results show that with an increase in the fraction of customers who seek price matching, the store’s profits initially decrease and then increase. While price matching could be used even when customers do not exhibit showrooming behavior, we find that it is more effective when customers do showrooming. We then study exclusivity of product assortments as a long-term strategy to counter showrooming. This strategy can be implemented in two different ways: (1) by arranging for exclusivity of known brands (e.g., Macy’s has such an arrangement with Tommy Hilfiger) or (2) through the creation of store brands at the brick-and-mortar store (T. J. Maxx sells a large number of store brands). Our analysis suggests that implementing exclusivity through store brands is better than exclusivity through known brands when the product category has few digital attributes. However, when customers do not showroom, the known-brand strategy dominates the store-brand strategy. The online appendix is available at https://doi.org/10.1287/mnsc.2017.2764 .

Refined Models for Efficiency-Driven Queues with Applications to Delay Announcements and Staffing
Authors: Huang Junfei , Mandelbaum Avishai , Zhang Hanqin , Zhang Jiheng 
Published: July 2017

Data has revealed a noticeable impact of delay-time-related information on phone-customers; for example and somewhat surprisingly, delay announcements can abruptly increase the likelihood to abandon (hang up). Our starting point is that the latter phenomena can be used to support the control of queue lengths and delays. We do so by timing the announcements appropriately and determining the staffing levels accordingly. To this end, we model a service system as an overloaded GI/M/s + GI queue, in which we seek to minimize the number of servers, s, subject to quality-of-service constraints (e.g., fraction abandoning), while accounting for the instantaneous (hence discontinuous) impact of an announcement on the distribution (hazard rate) of customer patience. For tractability, our analysis is asymptotic as s increases indefinitely, and it is naturally efficiency-driven (namely the servers are highly busy, and hence essentially all customers are delayed in queue prior to service). This requires one to go beyond existing theory, which turns out to be too crude for our needs (e.g., it requires a continuous hazard rate of impatience and hence cannot be applied). We thus develop a refined process and steady-state models, and use them to solve our minimization problem and more. The value and accuracy of our models are demonstrated via extensive numerical experiments. The online appendix is available at https://doi.org/10.1287/opre.2017.1619 .
Dynamic Inventory Management with Total Minimum Order Commitments and Two Supply Options
Authors: Wang Tong , Gong Xiting , Zhou Sean X. 
Published: July 2017

We study optimal policies for dual-supply inventory systems where a firm commits to buying a total minimum quantity from both supplies or two separate total minimum quantities from each supply over a finite planning horizon. The two supply options differ in their costs and lead times. For the system under the joint commitment, the optimal policy has a simple structure and can be fully characterized by three critical numbers in each period. For the system under the separate commitments, we show that the optimal order quantities in each period are monotonic in the starting inventory and the remaining commitments with bounded sensitivity. Moreover, we establish convergence results on the optimal order quantities when the committed quantity from either supply approaches infinity. These findings highlight the effects of order commitments on the optimal inventory policies. On the basis of these results, we develop a simple heuristic for the system under separate commitments and show numerically that it performs very well. The numerical study further shows that the firm could incur a considerable loss if it ignores or overemphasizes the order commitments when managing its inventory. Finally, we conduct numerical analysis to derive insights into the firm’s supply contract selection in the presence of minimum order commitments.

Considera aspectos del entorno e internos, prioriza necesidades y propósitos, ordena su implantación y somete el sistema a interacciones. </p><p>La investigación parte de la consulta a expertos en cada modelo de gestión, explora las metodologías existentes para integrar sistemas de gestión, toma la transdisciplinariedad mediante la reflexión todo-parte: entorno-empresa (sistema), relaciona los requisitos de cada norma con los siete saberes necesarios para la educación del futuro y como resultados se obtienen el modelo de gestión y la metodología para la integralidad. La metodología se aplica y luego se concluye que permite incrementar la probabilidad de conseguir los objetivos empresariales y hacer viable a la empresa como sistema. </p><p>La metodología es aplicable en organizaciones públicas o privadas que no solo requieren cumplir normas, sino que deben ser sostenibles en el tiempo, con influencias transformadoras como pensamiento global, cambio, finitud de los recursos naturales, incertidumbre, productividad e información virtual.</p>
Latin America in times of Neoliberal Restoration. What should we do?
Authors: Mora-Ramírez Andrés 
Published: July 2017

This essay offers an interpretation of the Latin America conjuncture of the last two/three years. On one hand, the conjuncture is characterized by what the analyst call de end of the progressive national and popular cycle. On the other hand the conjuncture is marked by the electoral rising of the right wing governments and parties,they are driving the restoration of the neoliberal project in the region. We present a contextualization of this double process and its main conflict dimension and we reflect from a position of identification and critical accompaniment of the national, popular, progressive, Latin American project. We also reflect on the need of the social movements, political parties and organic intellectuals of the Latin American left wing to assume, as a task, the dispute for the political and cultural hegemony vis-a-vis of the project of reviving the neoliberalism.

Neste artigo socializamos parte da experiência vivida no âmbito de um subprojeto Pibid (Programa Institucional de Bolsa de Iniciação à Docência) no contexto de uma escola municipal de ensino fundamental I de uma cidade do interior do estado de São Paulo. Problematizamos o lugar do professor supervisor no contexto do Pibid quem é responsável por acompanhar e supervisionar as atividades dos bolsistas de iniciação à docência no ambiente escolar. Discutimos quais os saberes necessários para o professor supervisor. Para isso, socializamos escritos elaborados pela professora supervisora e pelos bolsistas e que ficaram registrados no caderno coletivo; também trazemos relatos individuais dos bolsistas que legitimam o papel do professor supervisor enquanto formador. O trabalho deixa em evidência que a formação inicial dos bolsistas no contexto escolar é favorecido pelas práticas formativas do professor supervisor do Pibid. Com isto, o Pibid, além de contribuir efetivamente na constituição docente dos futuros professores, afiança a parceria da escola com a universidade, uma parceria que legitima a colaboração entre as duas instâncias, ambas consideradas como legítimos espaços formativos.
