Lean towards learning: connecting Lean Thinking and human resource management in UK higher education

From its origins in the automotive industry, Lean Thinking is increasingly being seen as a solution to problems of efficiency and quality in other industries and sectors. In recent years attempts have been made to transfer Lean principles and practice to the higher education sector with indications of mixed consequences and debate over its suitability. This paper contributes to the debate by drawing evidence from thirty-four interviews conducted across two UK universities that have implemented Lean in some of their activities and we pay particular attention to the role of the HR function in facilitating its introduction. The findings suggest there are problems in understanding, communicating and transferring Lean Thinking in the higher education context; that, despite HR systems being vital facets of Lean, HR professionals are excluded from participation; and that as a consequence the depth and breadth of Lean application in the two institutions is very limited

The effects on boar reproductive efficiency of exposure to females during rearing

Thirty-two boars (16 littermates) were reared from 3½ to 5½ months in either an all-male group or with fence-line exposure to cycling sows and gilts. Exposure to females did not significantly increase testicle or accessory gland weights, sperm production, or libido score. Boars that displayed more sexual activity (mounts and sheath sniffs) from 3½ to 5½ months of age performed superiorly in mating tests at 5½ and 7½ months of age. Libido scores of littermate boars were very similar.; Swine Day, Manhattan, KS, November 13, 198

Idiopathic granulomatous mastitis masquerading as carcinoma of the breast: a case report and review of the literature

BACKGROUND: Idiopathic granulomatous mastitis is an uncommon, benign entity with a diagnosis of exclusion. The typical clinical presentation of idiopathic granulomatous mastitis often mimics infection or malignancy. As a result, histopathological confirmation of idiopathic granulomatous mastitis combined with exclusion of infection, malignancy and other causes of granulomatous disease is absolutely necessary. CASE PRESENTATION: We present a case of a young woman with idiopathic granulomatous mastitis, initially mistaken for mastitis as well as breast carcinoma, and successfully treated with a course of corticosteroids. CONCLUSION: There is no clear clinical consensus regarding the ideal therapeutic management of idiopathic granulomatous mastitis. Treatment options include expectant management with spontaneous remission, corticosteroid therapy, immunosuppressive agents and extensive surgery for refractory cases

Investigation of Red-cockaded Woodpeckers in Virginia: Year 2019 Report

The Virginia population of red-cockaded woodpeckers is the northernmost throughout the species range and has been in eminent danger of extinction for more than 30 years. The Piney Grove Preserve represents a nucleus for recovery in the state and the focus of a multi-organizational partnership designed to increase the population to a sustainable level. The partnership has executed a program of aggressive habitat management, cavity-tree management and woodpecker population monitoring and management that has resulted in a quadrupling of the breeding population since the early 2000s. During the 2019 breeding season, Piney Grove Preserve supported 15 potential breeding groups (including one in the Big Woods) that produced 27 fledglings. All groups made breeding attempts, including the cluster in Big Woods for the first time, though three clusters (10, 17, and 18) failed to produce fledglings. The population as a whole had a reproductive rate of 1.8±0.35 (mean±SE) young/breeding group. The 13 groups that made breeding attempts had a success rate of 80% (12 of 15). Fledging rate for the 12 productive pairs was 2.3±0.32. Of the 61 eggs followed in 2019, 40 (65.6%) hatched, 21 (55.7%) survived to banding age, and 28 (45.9%) fledged. Birds that fledged included 18 females, 9 males, and 1 of unknown sex. Fifteen of these birds were retained and detected during the winter count and two (both male) were translocated to Great Dismal Swamp, NWR on 17 October. During the calendar year of 2019, 101 individual red-cockaded woodpeckers were identified within Piney Grove preserve including 72 birds that were hatched at Piney Grove during previous years and 29 nestlings that fledged during the 2019 breeding season. Forty-one birds (41%) were in their fourth year or more and ten birds (10%) were at least in their tenth year. One bird was fifteen years old (sixteenth calendar year). Moving into the breeding season there were 65 birds were identified within Piney Grove Preserve distributed among 15 clusters. This ties 2017 as the highest number of adults that Piney Grove has ever carried into the breeding season. The number of birds per cluster varied from two to seven with a mean of 4.33±0.45 (mean+SE). Seventy-seven birds were detected during the 2018 winter survey. This represents a 5% increase over the winter of 2018 and a 13% increase over the winter of 2017. Birds present include 15 of the 29 birds fledged in 2017 and 62 adult birds hatched in previous years. Group size in winter ranged from two to nine birds and averaged 5.13 ± 0.56 (mean±SE) birds per group

Entanglement Sharing and Decoherence in the Spin-Bath

The monogamous nature of entanglement has been illustrated by the derivation of entanglement sharing inequalities - bounds on the amount of entanglement that can be shared amongst the various parts of a multipartite system. Motivated by recent studies of decoherence, we demonstrate an interesting manifestation of this phenomena that arises in system-environment models where there exists interactions between the modes or subsystems of the environment. We investigate this phenomena in the spin-bath environment, constructing an entanglement sharing inequality bounding the entanglement between a central spin and the environment in terms of the pairwise entanglement between individual bath spins. The relation of this result to decoherence will be illustrated using simplified system-bath models of decoherence.Comment: 5 pages, 1 figure v2: 6 pages 2 figures, additional example and reference

Investigation of Red-cockaded Woodpeckers in Virginia: Year 2020 Report

The Virginia population of red-cockaded woodpeckers is the northernmost throughout the species range and has been in eminent danger of extinction for more than 30 years. The Piney Grove Preserve represents a nucleus for recovery in the state and the focus of a multi-organizational partnership designed to increase the population to a sustainable level. The partnership has executed a program of aggressive habitat management, cavity-tree management and woodpecker population monitoring and management that has resulted in a quadrupling of the breeding population since the early 2000s. During the 2020 breeding season, Piney Grove Preserve supported 15 potential breeding groups (including one in the Big Woods) that produced 30 fledglings. All groups made breeding attempts, including the cluster in Big Woods for the second time, though two clusters (cluster 8 and Big Woods) failed to produce fledglings. The population as a whole had a reproductive rate of 2.0 ±0.31 (mean±SE) young/breeding group. The 15 groups that made breeding attempts had a success rate of 86.7% (13 of 15). Fledging rate for the 13 productive pairs was 2.3±0.64. Of the 63 eggs followed in 2020, 34 (54.0%) hatched, 34 (54.0%) survived to banding age, and 30 (47.6%) fledged. Birds that fledged included 21 females and 9 males. Seventeen of these birds were retained and detected during the winter count and four (two males and two females) were translocated to Great Dismal Swamp, NWR on 07–08 October. During the calendar year of 2020, 102 individual red-cockaded woodpeckers were identified within Piney Grove Preserve including 72 birds that were hatched at Piney Grove during previous years and 30 nestlings that fledged during the 2020 breeding season. Thirty-one birds (41%) were in their fourth year or more and nine birds (10%) were at least in their tenth year. One bird was 16 years old (17th calendar year). Moving into the breeding season there were 67 birds identified within Piney Grove Preserve distributed among 15 clusters. This is the most birds Piney Grove has carried heading into the breeding season (two more than in 2017 and 2019). The number of birds per cluster varied from two to seven with a mean of 4.33±0.45 (mean+SE). Eighty birds were detected during the 2020 winter survey. This represents a 5% increase over the winter of 2019 and a 13% increase over the winter of 2018. Birds present during the winter survey included 17 of the 30 birds fledged in 2020 and 63 adult birds hatched in previous years. Group size in winter ranged from two to nine birds and averaged 5.04 ± 0.50 (mean±SE) birds per group
