The Impact

The value delivered by design thinking is almost always seen to be improvements in the creativity and usefulness of the solutions produced. This paper takes a broader view of the potential power of design thinking, highlighting its role as a social technology for enhancing the productivity of conversations for change across difference. Examined through this lens, design thinking can be observed to aid diverse sets of stakeholders’ abilities to work together to both produce higher order, more innovative solutions and to implement them more successfully. In this way, it acts as a facilitator of the processes of collectives, by enhancing their ability to learn, align and change together. This paper draws on both the author’s extensive field research on the use of design thinking in social sector organizations, as well as on the literature of complex social systems, to discuss implications for both practitioners and scholars interested in assessing the impact of design thinking on organizational performance.

Computational Strategy

A high-order compact-differencing and filtering algorithm, coupled with the classical fourth-order Runge–Kutta scheme, is developed and implemented to simulate aeroacoustic phenomena on curvilinear geometries. Several issues pertinent to the use of such schemes are addressed. The impact of mesh stretching in the generation of high-frequency spurious modes is examined and the need for a discriminating higher-order filter procedure is established and resolved. The incorporation of these filtering techniques also permits a robust treatment of outflow radiation condition by taking advantage of energy transfer to high-frequencies caused by rapid mesh stretching. For conditions on the scatterer, higher-order one-sided filter treatments are shown to be superior in terms of accuracy and stability compared to standard explicit variations. Computations demonstrate that these algorithmic components are also crucial to the success of interface treatments created in multi-domain and domain-decomposition strategies. For three-dimensional computations, special metric relations are employed to assure the fidelity of the scheme in highly curvilinear meshes. A variety of problems, including several benchmark computations, demonstrate the success of the overall computational strategy.

The Impact

Purpose – The purpose of this article is to understand how and why consumers resist or accept product rebranding. It seeks to identify and to quantify the drivers of attitudes toward this marketing practice to guide marketing managers in the execution of an effective changeover. Design/methodology/approach – The research is conducted in three stages. First, a qualitative study is run among 45 consumers to identify variables that might influence attitudes toward product rebranding. Second, a review of literature on the emotion of surprise is carried out to specify the relationships between the variables previously identified and to formulate hypotheses. Third, a quantitative study is conducted among 480 consumers to test the hypotheses and to quantify the impact of each variable. Findings – Surprise impacts attitudes toward product rebranding through a three-way process (automatic, higher-order cognitive, higher-order affective): a direct negative effect, an indirect effect mediated by incomprehension about the reasons for the change and an indirect effect mediated by the negative emotions generated by the change. Moreover, trust in firms diminishes the negative effects of anger, fear and sadness on attitudes toward product rebranding. Research limitations/implications – The research offers a better understanding of processes involved in the building of consumer attitudes toward brand name change. However, it only constitutes a first step in the attempt to understand the phenomena. Practical implications – This practice of brand name change is increasingly popular, but marketing managers are skeptical about the best way to implement it. The paper provides a better understanding of consumer reactions to product rebranding, so that marketing managers can make better decisions. It reveals guidance for successful brand name changes. Originality/value – This paper is the first to propose and to test a comprehensive model of the mental processes involved in the building of consumer attitudes toward product rebranding.

Order Dispersion

The transmission speed of optical network strongly depends on the impact of higher order dispersion. In presence of coherent crosstalk, which cannot be otherwise controlled by optical filtering, the impact of higher order dispersions becomes more pronounced. In this paper, the general expressions, that describe pulse deformation due to second- and fourth-order dispersions in a single-mode fiber, are given. The responses for such even-order dispersions, in presence of coherent crosstalk, are characterized by waveforms with long trailing edges. The transmission quality of optical pulses, due to both individual and combined influence of second- and fourth-order dispersions, is studied in this paper. Finally, the pulse shape and eye diagrams are obtained.

Order State

AbstractReasoning about program equivalence is one of the oldest problems in semantics. In recent years, useful techniques have been developed, based on bisimulations and logical relations, for reasoning about equivalence in the setting of increasingly realistic languages—languages nearly as complex as ML or Haskell. Much of the recent work in this direction has considered the interesting representation independence principles enabled by the use of local state, but it is also important to understand the principles that powerful features like higher-order state and control effects disable. This latter topic has been broached extensively within the framework of game semantics, resulting in what Abramsky dubbed the “semantic cube”: fully abstract game-semantic characterizations of various axes in the design space of ML-like languages. But when it comes to reasoning about many actual examples, game semantics does not yet supply a useful technique for proving equivalences.In this paper, we marry the aspirations of the semantic cube to the powerful proof method of step-indexed Kripke logical relations. Building on recent work of Ahmed et al. (2009), we define the first fully abstract logical relation for an ML-like language with recursive types, abstract types, general references and call/cc. We then show how, under orthogonal restrictions to the expressive power of our language—namely, the restriction to first-order state and/or the removal of call/cc—we can enhance the proving power of our possible-worlds model in correspondingly orthogonal ways, and we demonstrate this proving power on a range of interesting examples. Central to our story is the use of state transition systems to model the way in which properties of local state evolve over time.

The Impact

A large, multicampus, public medical school underwent curricular renewal, emphasizing a student-centered approach with 50% of all course contact time devoted to active learning. Determining the impact of active learning on student engagement and higher order skill (HOS) proficiency was the primary aim of this study. Following Institutional Review Board approval, two cohort groups of first-year medical students were enrolled. The first cohort ( n = 54) included students before curriculum reform in the legacy curriculum (LC). The second cohort ( n = 73) included students completing studies in the renewed curriculum (RC). Near the end of the first year of medical school, both cohorts completed a validated survey of student engagement, and a proctored problem-based assessment of HOS proficiency [Collegiate Learning Assessment (CLA+)]. Results indicated RC students perceived greater levels of engagement than LC (39.5+5.8 vs. 33.3+5.6), and greater reliance on HOS, including analysis, synthesis, and application. However, there were no significant differences between cohorts in proficiency of HOS when assessed by the CLA+ (LC = 1,878 ± 161 vs. RC = 1,900 ± 157). Additionally, poor correlation between engagement and HOS for both LC and RC indicated more engaged students do not necessarily possess greater HOS proficiency. Ceiling effect may explain results as medical students enter medical school as highly skilled learners with potentially little room for improvement. It will be informative to continue to track engagement and HOS of both cohort groups as they continue their medical studies.

Abstract: Malaysian schools have been implementing i-Think program as a means to develop higher order thinking skills among primary and secondary school students since 2013. Thus, there is a need to assess the implementation of the i-Think program since it was made compulsory almost seven years ago. This paper reports a scoping review of research activities conducted on the implementation of the i-Think program in Malaysian schools to synthesize studies on the implementation of the i-Think program in the classrooms; teachers' and students’ acceptance of the program; examine its impact on HOTS and students’ achievement; and to identify and disseminate the gaps in the works of literature. Forty articles were reviewed and the results indicated that the data on how i-Think programs were implemented in classrooms were so small that no definite conclusions could be made. Results on both students' and teachers’ levels of knowledge on i-Think maps were mixed. Majority of studies showed that i-Think maps significantly enhanced students’ achievement. However, no study measured the impact of i-Think on HOTS despite researchers' claim that i-Think maps had stimulated students’ HOTS. Thus, future studies should focus on showing correlation between i-Think and HOTS by using a validated measurement scale to assess students’ HOTS, development of valid and reliable measurement scale to gather a large pool of data to illustrate more comprehensively the status of i-Think implementation in schools throughout Malaysia, support systems provided to teachers at school and district level, and identifying barriers that hinders teachers from implementing i-Think program. Keywords: HOTS, i-Think Maps, Malaysian schools, Scoping review.
