Many design tasks are subject to changes in goals or constraints. For instance, a client might modify specifications after design has commenced, or a competitor may introduce a new technology or feature. A design team often cannot anticipate such changes, yet they pose a considerable challenge. This paper presents a study where engineering teams sought to solve a design task that was subject to two large, unexpected changes in problem formulation that occurred during problem solving. Continuous design data was collected to observe how the designers responded to the changes. We show that high- and low-performing teams demonstrated very different approaches to solving the problem and overcoming the changes. In particular, high-performing teams achieved simple designs and extensively explored small portions of the design space; low-performing teams explored complex designs with little exploration around a target area of the design space. These strategic differences are interpreted with respect to cognitive load theory and goal theory. The results raise questions as to the relationship between characteristics of design problems and solution strategies. In addition, an attempt at increasing the teams’ resilience in the face of unexpected changes is introduced by encouraging early divergent search.

Designers must often create solutions to problems that exhibit dynamic characteristics. For instance, a client might modify specifications after design has commenced, or a competitor may introduce a new technology or feature. This paper presents a cognitive study that was conducted to explore the manner in which design teams respond to such situations. In the study, teams of undergraduate engineering students sought to solve a design task that was subject to two large, unexpected changes in problem formulation that were introduced during solving. High- and low-performing teams demonstrated very different approaches to solving the problem and overcoming the changes. The results indicate that there may exist a relationship between problem characteristics and fruitful solution strategies.

Background:Telemedicine counseling (TMC) has gained rapid development during the COVID-19 pandemic. The prospect of using this technology in rheumatology was based on the possibility of getting maximum information about the patient during the survey, examination and interpretation of laboratory and instrumental data, that is excepting direct contact with the patient. Several rheumatological clinics have reported on the success of using TMC. However, there is very little data of the difficulties that can be encountered when organizing this process.Objectives:To characterize the identified problems during TMC in rheumatology, to suggest potential directions for their elimination.Methods:Since June 2021, on the basis of the Medical Association “New Hospital”, Yekaterinburg, Russian Federation, 76 TMCs have been performed on the profile of rheumatology in patients aged 29 to 71 years. Of these, 13 applied to the primary TMC, the other patients were preliminarily examined in person. The consultation included the preliminary acquaintance with the examination results, a 20-minute video communication and writing of a conclusion. After each TMC, a survey was conducted between the doctor and the patient, including the identified deficiencies in counseling. The frequency of identified problems is presented as an absolute indicator and as a percentage of the total number of TMCs performed.Results:We noted a high degree of patient satisfaction: 74 (97.4%) responded that they received answers to all. However, according to the doctor, the following groups of problems were identified.[1]Technical problems in 29 (38.2%): most often there were various problems with the Internet, but there were also registered: the end of the charge on the patient’s tablet, the patient was not registered in the electronic queue. Elimination of these violations depends on the work of IT-specialists, but each consulting physician should be prepared for an immediate transition to an alternative form of communication (for example - telephone).[2]Lack of objective examination, leading to the impossibility of correct remote diagnosis - 8 (10.5%). This problem was identified due to the inability to establish the presence or absence of arthritis during the initial diagnosis (6 cases) and to clarify the nature of the rash (2 cases). All patients are invited for a face-to-face consultation.[3]The need to write prescriptions for psychotropic drugs - 12 (15.8%), which under the conditions of national legislation cannot be done in the TMC regime.[4]The time spent directly on remote communication with the patient was 17.2 minutes (from 8 to 31), however, taking into account the study data and writing the conclusion, the total time was 40.7 minutes (from 21 to 73). Thus, it turned out that the average time for remote and face-to-face consultations is the same, while TMC’s payment is only about 50% of the face-to-face consultation. This situation reduces the doctor’s interest in carrying out TMC. The solution to the problem is associated with reducing the time for the documentation process through technical improvements. In addition, of the 9 patients in whom the TMC process lasted 60 minutes or more, 5 were diagnosed with fibromyalgia. It is possible that with a previously established diagnosis of fibromyalgia, only face-to-face counseling should be recommended to patients.Conclusion:The TMC system is promising, however, there are a number of problems that need to be improved, since they can reduce the doctor’s interest in using this technology.Disclosure of Interests:None declared

Abstract: When faced with privatization by the Ontario government, the public educational broadcaster TVOntario took a pro-active stance in the face of the neo-liberal ideology of reduced public expenditure and institutional restructuring. TVO won short-term salvation by embracing market model methods, but in so doing it may have lost its niche as a public educational broadcaster. It now faces two major policy challenges. It must balance its general-audience broadcast arm with its newly refocused educational arm and it must negotiate possible political interference from the imperative to connect the government's newly revised school curricula to its new technology-in-education arm. This paper also situates the TVO example as a rejection of the privatization agenda of the Government of Ontario. Finally, this paper uses the TVO example to raise questions about hybrid models of broadcasting. Résumé: Pour éviter que le gouvernement de l'Ontario ne la privatise, la station éducative publique TVOntario a adopté une position qui prend les devants face à la volonté néolibérale de réduire les dépenses publiques et restructurer les institutions. À court terme, TVO s'est protégé en adoptant des méthodes axées sur le marché, mais celles-ci lui ont peut-être coûté son créneau particulier à titre de diffuseur éducatif public. En effet, TVO doit maintenant relever deux défis politiques imposants. La station doit équilibrer le besoin de s'adresser à un auditoire général avec celui remis au point d'offrir des émissions éducatives. En outre, elle doit parer à des interventions politiques possibles émanant de son obligation de relier le nouveau curriculum scolaire à sa nouvelle branche consacrée à la technologie dans l'éducation. Cet article discute de TVO comme manifestant un rejet des projets de privatisation du gouvernement ontarien. Finalement, l'article utilise l'exemple de TVO pour soulever des questions sur des modèles de radiodiffusion hybrides.

Organizations are facing many challenges to remain relevant in the face of new technology, emerging markets, and changing consumer behaviors. Many organizations look to become learning organizations with knowledge management strategies to leverage their knowledge assets and continuously innovate their strategies and products. However, organizations struggle to achieve success with knowledge management because their organizational culture does not support knowledge-sharing and must be adapted for this new behavior. Knowledge must flow through the organization, and so, therefore, these necessary behaviors must work within the existing corporate culture. Observations from a case study at a software company are discussed, and a new knowledge management model, the Knowledge Management Triangle, is introduced. The Knowledge Management Triangle is a simple model to explain and implement knowledge management within organizations and is customizable to work within the organization's culture to ensure the new knowledge management behaviors are appropriately adopted.

Several recent studies have warned that there will be widespread water shortages in many regions of the USA in the near future largely because of high demand for water in the production of electricity. This study reviews studies addressing electricity generation and water availability and concludes that electricity production is not likely to lead to water shortages in most regions for several reasons. First, the alarmist studies erroneously rely on water withdrawals rather than water consumption to measure gaps between water demand and supply. Second, these studies fail to account for market dynamics, which will lead to improvements in greater water recycling and reuse as well as new resources on the supply side, and conservation and improved efficiency via new technology on the demand side. Electricity is increasingly generated by low water use technologies such as solar and wind. In addition, fossil-fired power plant technologies exist that greatly reduce water withdrawals and consumption. As water prices rise in the face of tighter supplies these technologies will become more attractive. Third, policies designed to overcome market failures related to pricing regulation, water rights, and government boundaries can reduce, if not eliminate, widespread electricity and water shortages.
