Given that we were interested not only in specificity and variety, but also in the functionality of causal connective expressions, our objective in the present study was threefold. First, to identify the variety of connective expressions connectives and how to determine if a signal is causal phrases used to signal causal relations in Spanish.

Second, to determine whether a relationship of specificity exists between connective expressions and particular types of causal relations. Third, to describe the functionality of those connective expressions. We analyzed a corpus of 2, causal coherence relations previously annotated and identified in a corpus of academic texts. These devices were grouped into what is relationship building in hospitality industry main functional classes: connectives and cue phrases.

Regarding the functionality of the signals, we found that 8 of the most frequent connective expressions were used to signal different relations. As for specificity, in terms of syntactic categories, it was observed that various conjunctions and conjunctive adverbs specialize in signaling specific relations. This interest has given rise to studies that explore patterns of signaling from different theoretical and methodological approaches.

From an approach that assumes coherence relations as explicit or implicit, studies have shown that some causal connectives specialize in expressing certain types of causal relations. This specialization is directly related to the notion of specificity proposed by Spoorenwho claims that a coherence relation is said to be specified, when it is marked by a connective that is prototypically used to encode its meaning, and underspecified when is marked by one that is not.

The notion of specificity has also been explored by scholars interested in causal connectives, who refer to them as specified causal connectives or underspecified causal connectives, depending on the degree of subjectivity a connective is involved with Li et al. This pattern of use has also been observed in other languages. A pattern of use different from specificity is that of polyfunctionality, which means that a connective can be used to signal different types of coherence relations Fischer, ; Blackwell, So, they focus on the variety of linguistic devices that may signal coherence relations, beyond connectives or discourse markers.

Studies from these two approaches have shed light on important issues regarding the signaling of causal coherence relations in Spanish; however, there are still other aspects that have causal research marketing definition understudied. One of them is the degree of specificity of the relation between particular types of coherence relations and connective expressions other than connectives or discourse markers.

Another aspect is the phenomenon of functionality of causal connective expressions, i. To go further into the description of these phenomena would not only widen our understanding of the way coherence relations are signaled in Spanish, it would also contribute to the delineation of the way connective expressions and causal coherence relations interact across languages.

In order to account not only for specificity and variety, but also for functionality in the signaling of causal coherence relations in Spanish, we take an integrative approach. Hence, our objective is threefold. Second, to determine whether a relationship of specificity between connective expressions and particular types of causal relations love is awesome feeling quotes. Given that the analysis was carried out in causal coherence relations identified in texts belonging to different academic genres used in university programs of Biology and Law, this study provides information regarding the signaling of causal coherence relations in academic contexts.

The article is organized as follows. First, we provide an introduction to the concept of causal coherence relations. Second, we present our conception of the relation between causal coherence relations and different connective expressions. Third, we present the methods. Fourth, we present and discuss the results. Finally, we discuss the implications of those results and provide the conclusion.

In spite of the fact that are open relationships good proposals vary considerably in terms of the types and number of relations or the specificity of the groupings, all of them include the group of causal relations. Important attempts have been made to describe and classify the coherence relations that encode causality and to explain their system and use.

One approach to describing coherence relations, particularly causal ones, is the Cognitive approach to Coherence Relations CCR Sanders, et al. In CCR, causality is defined as the implicational meaning that can be inferred between consecutive discourse segments. It is Semantic, if the link is established at the level of the propositional content; or Pragmatic, if it is established at the level of illocutionary meaning.

In further developments these values have been reformulated. Conversely, the order is Non- Basic when the opposite sequence is present. Provided this criterion reflects two different orders in which P and Q can be presented in the connected discourse segments, it distinguishes cause- consequence relations e.

As a result, S2 from consequence-cause relations S1 because S2 or claim-argument S1 since S2 from argument-claim S1 therefore S2 relations. A Negative relation holds when the relation between S1 and S2 involves the negation of the propositional content of one of the segments, while a Positive relation holds when there is no such a negation.

Negative relations also involve the violation of the expectations generated by P, whereas in Positive relations, Q is in line with what can be expected according to P. For instance, in Peter studied hard during the semester and he passed the course, Polarity is positive since passing a course Q is something one can expect for someone who has studied hard P. On the contrary, in Peter studied hard during the semester but he failed the course, Polarity is negative because failing a course Q is not a typical or expected result for someone who has studied hard P.

Since some negative relations involve an implication operation as described abovethey are considered as causal in CCR, different from cases like Peter studied hard during the semester but I did not where there is no implication. Let us consider examples 12and 3 to illustrate the classification of causal relations according to the CCR approach. How to determine if a signal is causal 2 [Los neurotransmisores regulan la transmisión de impulsos nerviosos.

In all cases, the Polarity is Positive since S2 does not imply a negation of S1. One may conclude, then, that these examples reflect the same type of causality and, therefore, that they could be classified under the same label. However, the difference between these examples can be identified by taking into account their Source of Coherence. According to Spooren and Sandersin 1 a Content relation holds since the states of affairs described in S1 and S2 occur in the physical world.

On the contrary, in 2 a Speech Act relation holds given that S2 is a claim by the author based on evidence presented in S1. In 3the relation is Epistemic since S2 is an inference made by the author based on what is complex economy economics evidence provided in S1. Therefore, according to the CCR approach, 1 is a case of Non- volitional cause, while 2 is Evaluation, and 3 Interpretation.

CCR has become an important discourse annotation scheme. Since the original proposal, several modifications and updates have been proposed for the interpretation and operationalization of the original primitives see Hoek, ; Hoek et al. For instance, a further distinction has been made in Source of Coherence, regarding the degree of Subjectivity causal relations may encode. The how to send a good first message online dating present an SoC is in the construction of the relation, the more subjective the relation is Epistemic relations.

Hence, if the SoC is absent, a relation will be objective How to determine if a signal is causal content relations. Following those principles, 1 can be classified as an objective relation because the causal link is established between two events of the physical world, without the intervention of an SoC. On the other hand, 2 and 3 are considered subjective since the causal link is mediated by the participation of an SoC. This approach has been used to annotate corpora of academic genres and school textbooks of different disciplines, allowing the identification of types of relations that vary in their frequency depending on the discipline.

These relations, labeled as Condition-Obligation, differ from the other conditional relations of the taxonomy in that the consequent Q is not an action that an agent performs voluntarily Condition-Action nor is a state that results when a condition is met Condition-Event but is an action that an agent is required to do See Appendix. The first has to do with the nature of the signal. Another issue in which there how to determine if a signal is causal to be no consensus has to do with the names given to connective expressions.

There is also lack of consensus regarding the way connective expressions are conceived. Despite the terminological and conceptual heterogeneity Dasthere is consensus on the fact that connective expressions comprise a functional class that signals the coherence relation that holds between two discourse segments. Though, there is no one-to-one link between connective expressions and the type of coherence relation they signal.

They may be fixed expressions, such as conjunctive adverbs, or less frozen expressions, such as prepositional phrases or other unsystematic constructions Das, ; Duque, In the present study, two main types of causal connective expressions are distinguished: causal connectives CCconceived as one-word or multi-word invariable expressions, whose main function is to signal the causal coherence relation that holds between discourse segments; and cue phrases CPwhich comprise those less frozen expressions that signal the causal coherence relation that holds between discourse segments, and may allow for syntactic modification.

Types and instances of causal coherence relations of the corpus. The original corpus consisted of how to determine if a signal is causal complete exemplarswords of academic genres Textbook, Disciplinary Text, and Research Articlewritten in Spanish and used in undergraduate programs of Law and Biology. Identification: this procedure started by distinguishing explicit from implicit relations based on whether or not they were marked, following some of Taboada and Das and Das conditions for considering an expression to be a how to determine if a signal is causal 1.

The scope of the function of a signal is a single discourse sequence comprising adjacent discourse segments in a relation. Signals mark relations that hold between two discourse segments. Signals constitute a functional class of lexical expressions drawn from different syntactic classes. As shown in 5the two discourse segments in square brackets are connected by a Claim-Argument relation.
