I truly LOVE your puzzles. Thank you for a new and challenging twist on the sudoku puzzle. These are, by far, my favorite variation. - Jane, Bethesda, USA This very interesting advancement to the puzzle has rekindled my family's interest in sudoku. It's just amazing that so many numbers can go together in only one way. - Peter, Banstead, UK After finishing my first sudoku puzzle, I was hooked. Having them in 3-D form only makes me want to do them 3 times more Thank you for cubing the complexity of the challenge. - Rory, Buderim, AUS About the Author: Richard John is the mastermind behind this uniquely challenging form of Sudoku that expands the 2-dimensional puzzle into a mind-bending cube of seemingly unsolvable numbers. His engineering background and perseverance helped create what you hold in your hands today. Richard runs a family business and teaches yoga. He lives with his wife, Claire, in Harare, Zimbabwe.

Healthcare improvements is constantly relevant and an important topic. Healthcare is frequently being called upon to be more cost-efficient and still fulfil demands regarding waiting times, quality and availability. Experience from structural changes in other contexts gives reason to be positive about the potential for logistics improvements in the healthcare sector as well. From a logistics perspective patients pass different care functions, units, organisations and health facilities. It is assumed that logistics management knowledge applied in healthcare can lead to lower costs, shorter waiting times, better patient service, shorter treatment times and increased capacity. This dissertation therefore presents an exploration of how logistics management theories can be operationalised in a healthcare context to understand care chain effectiveness. Theoretically, the operationalisation is done by systems theory creating compatibility between logistics management theories and the healthcare context. As a first step, features for a logistics system forms features for achieving care chain effectiveness. High care chain effectiveness is thus a desired condition and the care delivery system is the tool to achieve it. As the final step in the operationalisation the features for care chain effectiveness are in turn used to analyse today’s practices. Empirically, the research is based on qualitative data from a single case study with multiple units of analysis. It includes four care units at one of Sweden’s university hospitals, where the data is gathered through interviews, insight into management systems and document analysis. One of the main results is the 21 areas identified for analysing today’s practices by means of features for care chain effectiveness. Another main result is the four important concepts revealed through the operationalisation: Lead time - the episode of care from order to delivery as the amount of time for patient cases between first contact with healthcare and the last.Patient order fulfilment - fulfilment of patients’ needs, broken down into several smaller steps performed over time within different care units in one or several organisations, consisting of five sub-processes - order handling, diagnosis, treatment, follow-up, and discharge.True demand – patients’ needs that is to be met and thus sets what care to deliver, i.e. the production plan and the subordinate resource plan.System boundaries - defines which care units to include when focusing on the care delivery system’s performance as a whole and should be more important than the performance and productivity of each individual care unit. A number of direct suggestions for care chain improvement can also be found in the concluding remarks, for example that objectives linked to economic influx or penalty narrow the system and that lead time data on an aggregated level is needed to cover episodes of care. The theoretical contribution of the dissertation is to the field of logistics management through the methodological development of using these theories in a new context. The managerial contribution is to healthcare managers through providing opportunities to improve care chains primarily by means of a greater understanding of care delivery systems.

Packed with more than a hundred color illustrations and a wide variety of puzzles and brainteasers, Taking Sudoku Seriously uses this popular craze as the starting point for a fun-filled introduction to higher mathematics. How many Sudoku solution squares are there? What shapes other than three-by-three blocks can serve as acceptable Sudoku regions? What is the fewest number of starting clues a sound Sudoku puzzle can have? Does solving Sudoku require mathematics? Jason Rosenhouse and Laura Taalman show that answering these questions opens the door to a wealth of interesting mathematics. Indeed, they show that Sudoku puzzles and their variants are a gateway into mathematical thinking generally. Among many topics, the authors look at the notion of a Latin square--an object of long-standing interest to mathematicians--of which Sudoku squares are a special case; discuss how one finds interesting Sudoku puzzles; explore the connections between Sudoku, graph theory, and polynomials; and consider Sudoku extremes, including puzzles with the maximal number of vacant regions, with the minimal number of starting clues, and numerous others. The book concludes with a gallery of novel Sudoku variations--just pure solving fun! Most of the puzzles are original to this volume, and all solutions to the puzzles appear in the back of the book or in the text itself. A math book and a puzzle book, Taking Sudoku Seriously will change the way readers look at Sudoku and mathematics, serving both as an introduction to mathematics for puzzle fans and as an exploration of the intricacies of Sudoku for mathematics buffs.
