In particular, one of the reasons for marking a parameter as unsafe is to avoid the possibility of accumulating sub-terms during transformation. The combination of the structure of the pledge period (described below) and alcohol can easily lead to unsafe behavior. On the other hand, the algorithm determining deadlocks, unsafe regions, and so on, is very fast in dimension 2. Reports from our focus groups support this : various instances of unsafe behaviour on stairs were identified. Conversely, if either p is an unsafe consumer and/or q is an unsafe producer, then fusion may fail. Consequently, we can merge safe x-intervals satisfying these criteria with their adjacent unsafe x-intervals, hence forming one larger unsafe x-interval. In section 3, we present a producerconsumer model of functions and propose a new annotation scheme based on safe/unsafe producers and consumers. In our transformation algorithm, all unsafe producers in safe and unsafe consumers are generalised out prior to each fusion sequence. However, the system will add new preconditions rather than backtracking if an unsafe state is generated during synthesis. If we can change the annotations on these obstructing function calls, we may change the unsafe producers to safe ones. The obstructing function calls are nested with unsafe producers. Instead of marking these functions as unsafe, the re-annotation technique has transferred the unsafe markings to the obstructing function calls. In an unsafe language, program bugs that corrupt the run-time system are usually the most difficult to diagnose and have the most disastrous effects. A draining step is added if all actions that are positively related to a goal are unsafe because they cause an unsafe mixture to form. When needed, the planner will add a step to drain a unit in order to prevent the creation of an unsafe mixture of chemicals. Bugs in this metadata parsing can hurt completeness, but they can never lead to incorrect acceptance of an unsafe program. We now have a way to derive a safe interface and implementation, by adding type information to a generic, unsafe implementation. The deadlocks will just be considered as points in the unsafe region in the following. We will not distinguish between deadlocks and unsafe regions. The second solution has the advantage that a typecase statement could be provided which would not allow type-unsafe access. Thus, fusion can be selectively applied, as long as sub-terms which are unsafe to fuse can be identified. In our proposed model, we will classify producers and consumers as either safe or unsafe with respect to their amenability to safe fusion. Unsafe producers can be seen as producing function calls, in addition to constructor terms. With these additional considerations, the original unsafe producer now appears pseudo-safe. The second step requires that each set of sibling (mutually recursive) functions must be simultaneously transformed and regarded as potentially unsafe producers and unsafe consumers. They can be handled by marking them as unsafe. In addition, it illustrates the identification of safe and unsafe xintervals. Semi-naive optimization would be unsafe if it were applied to new subgoals that have never been encountered before. In fact, this can be very simply achieved by annotating all occurrences of obstructing calls as unsafe producers and unsafe consumers. Generalisation from this to spontaneous behaviours in nonexperimental settings is unsafe. Maintenance of one's own life-space was becoming increasingly difficult, amplifying a sense that the immediate environment had become unsafe and overwhelming. Understanding household fuel choice is of vital importance in the search for policies to combat unsafe cooking practices. Although during the real-world walks all roads were generally crossed safely, much of the road-crossing behaviour in the virtual environment was unsafe. However, some evidence of the willingness of households to pay to prevent the effects of drinking unsafe water also comes from households' defensive expenditures choices. The safe period is observed, but this is notoriously unsafe, particularly so in the girl with an irregular cycle. The planner will not act to avoid unsafe situations that do not involve mixing. Moreover, to remove duplicate update entries the debugger uses a type-unsafe algorithm that involves marking ref cells. Hence, it cannot handle expressions which contain unsafe tree-like subterms. A noticeable concern is that this alternative definition of double now has the syntactic form of both an unsafe producer and an unsafe consumer! According to our annotation scheme, this nesting is unsafe to fuse. The pre-order restriction is more limiting that the safe-unsafe criteria of our generalised deforestation, but the on-line cyclic restriction is something extra. In conclusion, the main route of transmission of brucellosis in our region is likely to be the consumption of unsafe dairy products. Perhaps the most important point is that destruction of known stocks would then leave any existing stocks in unsafe hands. Although this world is technologically unsafe, it is not impossible. In order to identify interesting/unsafe states, two things are needed. In some rare cases, this alternative state is safe, and so achievable, even though the hypothetical state is unsafe, and so unachievable. The repair of an unsafe procedure may require adding new actions into the body of the existing procedure. Finding the unsafe area is not that simple, and this will become clear in the examples. The same property holds for the (larger) unsafe regions. We refer to such a placement as a safe placement; a placement is unsafe otherwise. Specifically, the rates of a child having significant problems in social-emotional functioning and academic functioning increased significantly for children living in unstable or unsafe homes. If the cause of sickness and death is assumed to be other than a nutritional disorder, the animal is declared unsafe and is therefore discarded. His wife and his home occupied a very important place in his life and seemed to be his locus of safety in an unsafe present. The most important application is when a resident believes that a supervising physician is providing care that is substandard or unsafe. If they are thought unsafe for publication, as could well be the case, was it ethical to authorize the research at all? I t will attempt to remove all safe sub-terms by fusion transformation and leave the unsafe sub-terms untouched via parameter generalisation. As already argued, that assumption is almost certainly unsafe, though evidence is lacking to determine whether the practice shows any marked regional differences. Safety is defined in terms of unsafe situations. As in all forward-chaining systems, a procedure is considered safe unless some unsafe situation is caused by the procedure. If k 1 (x) is non-empty, the further delooping also decreases the unsafe region. There are no deadlocks in this system, and hence no unsafe region. Through this model, syntactic program properties are proposed to classify producers and consumers as either safe or unsafe. Also, blazed deforestation treats all atomic-type sub-terms as unsafe, and allows only safe tree-like sub-terms to be used. In this way, all the original unsafe producers can now be made safe. Our generalisation of the deforestation algorithm relies primarily on sufficient syntactic properties for classifying producers and consumers as either safe or unsafe. We apply static analyses to each function after transformation because syntactic properties are often changed (from unsafe to safe) by the transformation. With only variables in the unsafe arguments, there is no possibility of large arguments being duplicated or accumulated by direct unfolding. One way to handle unsafe producers is not to unfold them, as producers, during fusion. We not only need to prevent unsafe reference widening for confined types but also for generic types with variable type parameters. The second step is elimination of false safety by identifying (partial) false safe cells and merging them with their x-wise adjacent unsafe cells. Since = 1, 2, 3 are kinematic and = 4 is not, = 4 should be considered unsafe and avoided. Almost all of the potential dangers in the robot-man work environment are the result of combinations of unsafe conditions and unsafe actions. Failures not only are uneconomical, but also can have an unsafe outcome. Active monitoring of a child's coming and goings is a prudent parenting practice, especially in settings such as lowincome neighborhoods that are unsafe. However, the wholesale treatment of functions with obstructing calls as unsafe producers may be more stringent than necessary. In fact, many of the children that spent extra weeks playing in unsafe neighborhoods were forced to bear much greater risks than they would have faced in school. In an unsafe language, the programmer can access the underlying bit pattern of a data type; this tends in practice (and by convention) to force the compiler into predictable choices. Against the background of widespread irrational drug use, counterfeiting, and promotion of unsafe drugs in low-income countries, one would expect considerable research efforts in this area (17;31). Such a producer is unsafe because there is a chance that the obstructing function calls may be accumulated during transformation (since pattern-matching equations cannot consume them). In section 7, we showed that some pseudo-unsafe consumers (wrapped with the id function) can be converted to safe ones through the direct unfolding of non-recursive /-type functions. Neither is easily distinguishable as an "unsafe" speculator, and yet this is significantly more than simply a variation on the perennial theme that appearances are deceiving. He made the caveat that to seek a direct relationship between class structure and various forms of political action is not only simplistic but logically unsafe. The team members expressed the belief that the professional obligation to protect patients supersedes a patient's desire for a therapy that the team views to be largely unsafe. Note that dirt plays a crucial role since comparing against unevaluated parts of the result would drive the computation beyond what was originally computed which is unsafe. In fact, it is unsafe to assume that the intensity of direct competition between males should necessarily be reduced in monogamous species. One consequence of the present nonavailability of such a formal similarity metric is that it renders some comparisons unsafe. Therefore, heavy reliance on this single strategy is highly unsafe, and the timely development of alternative or complementary methods to chemical control is advisable. In any case, social prognosis is a notoriously unsafe activity, and it is one from which we might wisely refrain. Managers recognised that some older people were admitted to long-term care partly because their homes were unsuitable or unsafe. If adding a new action to a procedure causes an unsafe state to be formed, the system simply backtracks. An environmental audit of three farms that might have supplied salad vegetables to the implicated outlets did not reveal any unsafe agricultural practices. If a swallow remains unsafe or the assessor is uncertain at 48 hours then the patient should be referred to a speech and language therapist. The pictures show various unfoldings with the forbidden area and the unsafe regions below. The forbidden area is black, the unsafe area is grey and the safe area is white. In this case, the assumption is that labour cost improvements should not be achieved by means of resorting to unsafe work practices. Either unsafe features have to be exploited, or operations like constant time array updates have to be encapsulated in a monad. Note that because primitive functions (like *) cannot be unfolded, we have to annotate their arguments as unsafe. Even though unsafe producers should not be unfolded as producers, there is nothing to stop them from being unfolded as safe consumers. These examples are from corpora and from sources on the web.
