The aim of this paper is to investigate the relationship between post-traumatic stress symptoms resulting from relationship dissolution and coping style. The hypothesis was that some degree of post-traumatic stress symptoms would be evident among the sample and that the coping strategies of seeking social support, escape-avoidance, self-controlling and accepting responsibility would be associated with such symptoms. Eighty-eight university students who had experienced the dissolution of a romantic relationship over the preceding 24 months participated in the research. They were interviewed using the Impact of Event Scale (IES), the General Health Questionnaire (GHQ) and the Ways of Coping Questionnaire (WOC). The results showed that the mean score of intrusion was slightly higher than that of avoidance. The sample scored significantly higher in the IES items than one standardized sample of medical students but significantly lower in intrusion than another standardized sample of clinical patients. Fifty-one per cent of the sample scored above the cut-off of the GHQ. The results also showed that both intrusion and avoidance were significantly correlated with all GHQ items. The sample used the self-controlling coping strategy the most, followed by escape-avoidance and positive reappraisal. The sample also employed coping strategies of distancing and seeking social support. Stepwise multiple regression analyses showed that escape-avoidance, distancing, seeking social support and planful problem solving were significant predictors to the IES total. Escape-avoidance and accepting responsibility were significant predictors to the IES intrusion. Escape-avoidance and distancing were significant predictors to the IES avoidance. Escape-avoidance was the only significant predictor to the GHQ total.

The present study aimed to ascertain the extent to which people, following the dissolution of a dating relationship, experienced post traumatic stress symptoms. It also aimed to investigate the relationship between post traumatic stress and self-esteem and personality. The hypotheses were that there would be a severe degree of post traumatic stress symptoms experienced by the present samples, and that the personality factor, in particular, neuroticism, and low self-esteem would be associated with the samples' post traumatic stress symptoms. Sixty heterosexual subjects who had experienced a romantic relationship dissolution over the past 24 months were recruited for the study. They were interviewed with The results showed that 72 per cent of the subjects scored at or above the high IES symptom cut-off. Forty-three per cent scored above the cut-off of the GHQ-28. Significant correlations were found between the impact of the dissolution and general health. The present subjects were significantly less extroverted and neurotic than the standardized samples. Stepwise regression analyses showed that negative self-esteem significantly predicted avoidance and the total general health, and that neuroticism significantly predicted the total impact of the dissolution.

This study tests symmetry and homogeneity restrictions on a system of factor demand equations for central and western Canadian agriculture under the assumption that the variables are integrated processes and the demands represent cointegrating relationships. It is well known that the distribution of F‐statistics derived from ordinary least squares estimates in such systems are not distributed as the ratio of two independent χ2 random variables normalized by their degrees of freedom even asymptotically. Indeed, the use of traditional critical values of F‐statistics in such cases will severely underestimate the true critical values and therefore use of traditional critical values would tend to overreject symmetry and homogeneity restrictions. Bootstrapping techniques are employed to generate the true distribution of the F‐statistic so that the proper critical values can be compared with the calculated F‐statistic on symmetry and homogeneity. For both regions, the calculated F‐statistic is not rejected using the proper critical values but would have been strongly rejected using standard critical values. Results are consistent with the argument that the regularity of rejection of the parametric restrictions of symmetry and homogeneity found by Fox and Kivanda may be due to inappropriate assumptions regarding the time series properties of the data rather than a rejection of neoclassical production theory. This interpretation is consistent with arguments made by Clark and Coyle in their comments on Fox and Kivanda. Nous testons les constraintes de symétrie et d'homogénéité sur un système d'équations de demande de facteurs de production pour le secteur agricole du centre et de I‘ouest du Canada, en postulant que les variables sont des processus intégrés et que les demandes représentent des rapports cointegrants. Il est admis que dans des systèmes de ce genre les valeurs F dérivées des calculs des carrés latins ordinaires ne sont pas distribués comme le rapport de deux variables aléatoires χ2 indépendantes normalisées par leur degré de liberté, me soit ‐ce que de façon asymptotique. De fait, l'emploi, dans pareil cas, des valeurs critiques classiques de l'analyse statistique basée sur F comporte une grave sous‐estimation des vraies valeurs critiques, de sorte qu‘il risque de sur‐rejeter les constraintes de symétrie et d'homogénéité. Les techniques de rééchantillonnage bootstrap sont utilisées pour produire la vraie distribution des valeurs F, de telle sorte que les valeurs critiques convenables puissent être comparées aux valeurs F calculées, quant à la symétrie et à l'homogénéité. Pour les deux régions mentionnées plus haul, les valeurs F calculées ne sont pas rejetées lorsqu‘on utilise les valeurs critiques appropriées, mais elles le seraient fortement si on utilisait les valeurs critiques standards. Les résultats s‘accordent avec l‘hypothèse selon laquelle la régularité du rejet des restrictions paramétriques de symétrie et d'homogénéite observée par Fox et Kivanda s'expliquerait par des postulats erronés relatifs aux...

RESUMEN -Este estudio pretendía explorar 1) las diferencias existentes entre el sexo femenino y el masculino a la hora de manifestar síntomas de estrés postraumático tras la ruptura de una relación sentimental, 2) las diferencias en el estilo de amar que presenta cada sexo durante la relación y, 3) la interacción entre el sexo, el estrés traumático y las distintas maneras de expresar el amor. Valoramos la posibilidad de que ambos sexos se diferenciaran en cuanto a los síntomas de estrés postraumático tras la ruptura de una relación así como en los estilos de amar adoptados y asimismo, consideramos la posibilidad de que existiera una interacción significativa entre el sexo, el estrés traumático y los estilos de amar. Un total de 25 hombres y 40 mujeres participaron en el estudio y fueron entrevistados con la Escala de Impacto de Acontecimientos Vitales (IES), el Cuestionario de Salud General (GHQ) y la Escala de Actitud ante el amor (LAS). Los resultados no mostraron diferencias significativas entre ambos sexos en lo que al impacto que provocaba la ruptura se refiere, sin embargo, las mujeres padecían mayor disfunción social y depresión que los hombres. Los resultados también mostraron que existían diferencias en los estilos de amor "Eros" y "Agape". A pesar de ello, no se obtuvieron resultados significativos en las relaciones existentes entre el sexo, la gravedad del estrés traumático y los estilos de amar.

Long-term potato acreage trends show decline in Nova Scotia, stability in New Brunswick, and expansion on Prince Edward Island. The long-term trend for yield has been upward since the 1940s. Crop disposition has become primarily to processing in Nova Scotia and New Brunswick, but Prince Edward Island continues to dispose of much of its crop in the table market despite the growth of the processing sector. Contract growing of processing potatoes has provided farmers an opportunity to reduce price risk. The trend to larger farm acreages continues, although the number ofpotato farms in Prince Edward Island has been maintained with the province's large increase in total potato acreage. Crop rotations have converged on large-scale Maritime potato farms atpequencies that on Prince Edward Island have lead to the call for a mandatory three-year rotation. Les superfcies de culture de lapomme de terre esquissent a long terme une tendance a la baisse en Nouvelle-Ecosse, a la stabilitk au Nouveau-Brunswick et a I 'expansion dans 1 fle-du-Prince-Edouard. Quant au rendement, la tendance est a la hausse depuis les annees 1940. Lespommes de terre de la Nouvelle-Ecosse et du Nouveau-Brunswick sont essentiellement tranflormkes tandis que celles de 1 fle-du-Prince-Edouard sont en grande partie consommkes nature. La tendance en faveur du conditionnement de la pomme de terre a assure aux producteurs de pommes de terres une protection contre lesfluctuations desprix. La tendance en faveur de plus grandes exploitations de culture de la pomme de terre se poursuit, quoique le nombre d 'exploitations specialisees dans cette culture s 'est maintenu dans 1 'fle-du-Prince-Edouard. Lesprovinces ont enregistre une augmentation marquee de la superfcie de culture de lapomme de terre. Sur les grandes fermes de pommes de terre Maritimes, le systt?m de rotation de ces cultures a converge vers unepequence telle que celle qui a conduit a l'appel d'un systime obligatoire de rotation tri-annuel a I 'Ile-du-Prince-Edouard. Newfoundland supplying part of its requirements for table potatoes fromthis limited acreage, Atlantic Canada's potato industry is confined to the Mantime Provinces. According to 189 1 Census figures, each of the Maritime provinces had about the same potato acreage: Prince Edward Island 43,521, New Brunswick 42,703, and Nova Scotia 44,154 acres2. At the time the Mantimes potato industry was in decline. Soil fertility had diminished because of continuous cropping in potatoes and oats, and the coastal export trade was hamperedby the 1879 imposition of aU.S. Can. J. Agric. Econ. 45: 439-450
