Anatomy of Cerebellum

The cerebellum receives inputs from spinal cord, cerebrum, brainstem, and sensory systems of the body and controls the motor system of the body. The Cerebellum harmonizes the voluntary motor activities such as maintenance of posture and equilibrium, and coordination of voluntary muscular activity including learning of the motor behaviours. Cerebellum occupies posterior cranial fossa, and it is relatively a small part of the brain. It weighs about one tenth of the total brain. Cerebellar lesions do not cause motor or cognitive impairment. However, they cause slowing of movements, tremors, lack of equilibrium/balance. Complex motor action becomes shaky and faltering.

Detailed Balance $$=$$ Complex Balance $$+$$ Cycle Balance: A Graph-Theoretic Proof for Reaction Networks and Markov Chains

We further clarify the relation between detailed-balanced and complex-balanced equilibria of reversible chemical reaction networks. Our results hold for arbitrary kinetics and also for boundary equilibria. Detailed balance, complex balance, “formal balance,” and the new notion of “cycle balance” are all defined in terms of the underlying graph. This fact allows elementary graph-theoretic (non-algebraic) proofs of a previous result (detailed balance = complex balance + formal balance), our main result (detailed balance = complex balance + cycle balance), and a corresponding result in the setting of continuous-time Markov chains.

Standardized Assessment of Pharmacists' Patient Care Competencies:

Assessing the ongoing competence of practicing health care professionals requires regulators to balance complex demands of governments and the public, as well as interests and concerns of practitioners. A proliferation of models has evolved across professions and jurisdictions. In this article, we report on a model utilizing standardized assessment using best-practice measurement techniques and methods for evaluation of ongoing (i.e., post-registration) clinical competencies in the profession of pharmacy in Ontario, Canada. This model involves categorization of the profession into an active patient-facing and non patient-facing register, implementation of a learning portfolio requirement to replace mandatory continuing education credit accumulation, and the use of standardized assessment techniques, such as a multiple-choice test of clinical knowledge and an objective structured clinical examination (OSCE) of clinical reasoning and interpersonal skills. Lessons learned from the development, implementation and retrospective analysis of almost two decades of data from this program can provide regulators in diverse professions and different jurisdictions with tools for standardized assessment of patient care competencies.

Developing an offsetting programme: tensions, dilemmas and difficulties in biodiversity market-making in England

SUMMARYIn 2011, the UK government set in motion a process to establish a formal biodiversity offsetting programme in England, as an attempt to tackle biodiversity loss as a result of development. Drawing on critical approaches to the commodification of nature, this article traces the dilemmas encountered by the UK government in its endeavours to roll out a biodiversity offsetting programme in the English planning system. Based on 34 in-depth interviews with key stakeholders, documentary analysis and participant observation at policy-focused events, the paper aims to show how the promise of reconciling development and conservation proved difficult to deliver. In government attempts to enrol sympathetic actors, disputes emerged over the purpose and fine detail of the proposals. Deeper tensions were revealed in clashes between governmental emphasis on deregulation and advocates’ calls for strong mandatory rules and well-resourced oversight, while efforts to balance complex ecology with market demands for simplicity and certainty undermined the promise of objective biodiversity metrics delivering uncontroversial hard numbers. Though the English case is in many ways context-specific, the problems experienced raise wider political questions around establishing meaningful offsetting schemes in any part of the world.

Influence of Digging Date on Yield and Gross Return of Virginia-type Peanut Cultivars in North Carolina

Peanut (Arachis hypogaea L.) growers must balance complex interactions among cultivars, planting dates, environmental and physiological stresses during the growing season, and weather conditions at harvest when determining when to dig peanut. Ten field experiments were conducted in North Carolina from 1994 through 1996 to determine the influence of digging date on pod yield and gross return of virginia-type peanut. Beginning in mid- to late September, the cultivars NC 9, NC 10C, NCV-11, VA-C 92R, AgraTech (AT) VC-1, and NC 12C were dug on four dates approximately 7 d apart. Considerable variation in pod yield and gross return was noted among cultivars and experiments. Delaying digging increased pod yield and gross return in some but not all experiments. Greater variation in pod yield and gross return was observed for NC 10C than for AT VC-1 when compared across digging dates. Pod yield and gross return for NC9, NC V-11, VA-C 92R, and NC 12C were intermediate between NC 10C and AT VC-1. Of the cultivars evaluated, yield and gross return of AT VC-1 were the most stable over digging dates. These data suggest that growers should evaluate maturity of peanut in individual fields for each cultivar when determining when to dig. These data also suggest that factors other than maturity impact pod yield and gross return.
