1. One striking characteristic of the way in which accommodation and convergence of the eyes are organized is that although the two responses are usually tightly coupled, a brief period of binocular viewing through prisms that require extra convergence brings about a persistent, adaptive alteration in the relationship between the two responses: the vergence during monocular viewing of a target at a given distance is biased in a convergent direction. We sought to discover the role of the near-response neurons we have previously described in the monkey midbrain in such phoria adaptation. 2. Phoria adaptation was produced in two monkeys by having them view binocularly stereoscopic targets under conditions that mimicked prism viewing, i.e., the mirrors of the stereoscope were set so as to require more convergence than that associated with a real target at the same distance as the images seen in the stereoscope. The activity of 57 near-response neurons located dorsally and dorsolaterally to the oculomotor nucleus was recorded before and after adaptation while the monkeys monocularly viewed targets at a range of distances. 3. Comparison of a neuron's response in normal binocular viewing with the response when the accommodation and vergence stimuli were in conflict allowed us to distinguish 24 neurons that behaved as though they were related exclusively to the vergence response. 5 neurons that behaved as though they were exclusively related to the accommodation response, and 12 neurons whose firing was not so simply related to either response. We were unable to classify the remaining 16 near-response cells by this method. 4. In accommodation-related neurons, the relationship between firing rate and accommodation did not alter, or only altered slightly, when the animal's phoria was adapted. 5. The relationship between firing rate and vergence was unaltered by phoria adaptation in only a small proportion of vergence-related neurons, showing that most neurons do not carry the entire signal responsible for phoria adaptation. On the other hand, in the majority of vergence-related neurons the relationship between firing rate and accommodation was altered by phoria adaptation, showing that most neurons do carry part of the phoria adaptation signal. 6. The implication is that the increase in vergence observed after adaptation is mediated at more than one site. A proportion of the phoria adaptation signal is present at the level of the midbrain vergence-related neurons, with the remainder of the signal being added later, presumably at the motoneurons.

This paper is a contribution to the growing literature on the role of projective identification in understanding couples' dynamics. Projective identification as a defence is well suited to couples, as intimate partners provide an ideal location to deposit unwanted parts of the self. This paper illustrates how projective identification functions differently depending on the psychological health of the couple. It elucidates how healthier couples use projective identification more as a form of communication, whereas disturbed couples are inclined to employ it to invade and control the other, as captured by Meltzer's concept of "intrusive identification". These different uses of projective identification affect couples' capacities to provide what Bion called "containment". In disturbed couples, partners serve as what Meltzer termed "claustrums" whereby projections are not contained, but imprisoned or entombed in the other. Applying the concept of claustrum helps illuminate common feelings these couples express, such as feeling suffocated, stifled, trapped, held hostage, or feeling as if the relationship is killing them. Finally, this paper presents treatment challenges in working with more disturbed couples.

The role of arthroscopy in incipient and mild arthrosis, even combined with proximal tibial ostetomy, is well known and well documented. On the other hand, its role in the treatment of advanced arthrosis of the large joints, especially the knee, is a subject of controversy. The proponents of the use of arthroscopy in advanced arthrosis claim that meniscectomy, synovectomy, ostophytectomy, chondral lesion stabilization, arthroscopic release, plica and loose body removal greatly improve the quality of life for most patients, especially if followed by the use of viscoelastic injection, by diminishing pain and improving joint range of motion. The opponents claim that, even though the advantages are clear in the cases that refuse arthroplasty, in all the other cases the surgical indication should be total knee arthroplasty, as the clinical relief is temporary, but with all the risks of a surgical intervention. We have conducted an overview of the recent literature, in order to find objective evidence to sustain either point of view. We focused on articles published that included an objective measurement of before and after clinical status through clinical scores and objective measurements. We also focused on the follow-up period and on the evolution of the pathology after arthroscopy.

The Relationship

The relationship between the filter media and the behaviour of anaerobic bacteria was studied using anaerobic fixed-bed reactors. At an HRT of 48 hours, the number of suspended acidogenic bacteria was higher than those attached to the filter media. On the other hand, the number of attached methanogenic bacteria was more than ten times as higher than that of suspended ones. The numbers of suspended and deposited acidogenic and methanogenic bacteria in the reactor operated at an HRT of 3 hours were almost the same as those in the reactor operated at an HRT of 48 hours. Accumulation of attached bacteria was promoted by decreasing the HRT of the reactor. The number of acidogenic bacteria in the reactor packed sparsely with the filter media was higher than that in the closely packed reactor. The number of methanogenic bacteria in the sparsely packed reactor was lower than that in the closely packed reactor.

The role of infrastructure in encouraging transportation cycling in smaller cities with a low prevalence of cycling remains unclear. To investigate the relationship between the presence of infrastructure and transportation cycling in a small city (Lethbridge, AB, Canada), we interviewed 246 adults along a recently-constructed bicycle boulevard and two comparison streets with no recent changes in cycling infrastructure. One comparison street had a separate multi-use path and the other had no cycling infrastructure. Questions addressed time spent cycling in the past week and 2 years prior and potential socio-demographic and psychosocial correlates of cycling, including safety concerns. Finally, we asked participants what could be done to make cycling safer and more attractive. We examined predictors of cycling using gender-stratified generalized linear models. Women interviewed along the street with a separate path reported cycling more than women on the other streets. A more favorable attitude towards cycling and greater habit strength were associated with more cycling in both men and women. Qualitative data revealed generally positive views about the bicycle boulevard, a need for education about sharing the road and for better cycling infrastructure in general. Our results suggest that, even in smaller cities, cycling infrastructure may encourage cycling, especially among women.

Airway hyperresponsiveness after inhaled ozone in dogs may occur as a result of thromboxane release in the airway. In this study, two thromboxane receptor antagonists, L-655,240 and L-670,596, were used in doses that inhibit the response to an inhaled thromboxane mimetic, U-46619, to determine further the role of thromboxane in ozone-induced airway hyperresponsiveness. Dogs were studied on 2 days separated by 1 wk. On each day, the dogs inhaled ozone (3 ppm) for 30 min. On one randomly assigned day, 10 dogs received an infusion of L-655,240 (5 mg.kg-1.h-1) and 5 dogs received an infusion of L-670,596 (1 mg.kg-1.h-1); on the other day dogs received a control infusion. Airway responses to doubling doses of acetylcholine were measured before and after inhalation of ozone and were expressed as the concentration of acetylcholine giving a rise in resistance of 5 cmH2O.l-1.s from baseline (acetylcholine provocation concentration). The development of airway hyperresponsiveness after ozone was not inhibited by the thromboxane antagonists. The mean log difference in the acetylcholine provocative concentration before and after ozone on the L-655,240 treatment day was 0.62 +/- 0.12 (SE) and on the control day was 0.71 +/- 0.12 (P = 0.48); on the L-670,596 treatment day the mean log difference was 0.68 +/- 0.15 (SE) and on the control day it was 0.75 +/- 0.19 (P = 0.45). These results do not support an important role for thromboxane in causing ozone-induced airway hyperresponsiveness.

The Relationship

The present study investigated whether perception of receiving emotional support mediates the relationship between one partner’s giving of emotional support and the other partner’s depressive symptomatology using a population-based sample of 423 couples from the Changing Lives of Older Couples study. A path model was used guided by the Actor—Partner Interdependence Model. Results indicated that spouses’ giving emotional support was related to the degree to which their spouse reported receiving emotional support. Perception of receiving emotional support, in turn, was related to lower depressive symptomatology of the support recipient. Both husbands and wives can benefit from emotional support through their perception of receiving emotional support, and spouses’ perceptions, as well as their actions, should be considered in support transactions.

AbstractTaking into consideration two facts: that the structure of social life forces twins to part and that the presented roles in a pair are not equal, (one of the twins plays the role of a leader (L) and the other, the subordinate (P.)), one can ask the question — what meaning does the moment of parting have and what are its consequences?In order to do that, a survey was conducted, (a sample of 31 pairs of twins above the age of 30), in which every pair was asked the question: “Which one of you made the decision about parting?” The answer had two options: A – I, B – brother/sister. Out of 31 pairs of twins, 16 pairs chose the variant different from his brother or sister – that is A, B, admitting that the interpersonal conflict was the result of the parting. In 7 pairs, both twins chose the B variant – they withdrew from the conflict; and in 8 pairs they chose the A variant – looking for a compromise as the means of agreement.When analyzing the results of the survey, we can state the following:– in the relationship of twins, there is an interpersonal conflict;– the decision about parting is difficult with prevalent feelings of sadness and sorrow;– after parting, at least one of the twins has problems with preserving his identity and integrity of psychological space.Since the moment of parting is necessary and difficult, specialists and mainly parents are required to consciously change their position towards the relationship of twins. It has to be the result of applied educational methods which aim at creating subjectivity and equality of each of the twins before the moment of parting.

The Relationship

<p>Internal Marketing, a long-debated concept amongst academics and practitioners, is suggested to be a competitive advantage to organisations that utilise its practices. Often dismissed as merely selling the marketing of a product or service to employees within an organisation, Internal Marketing encompasses a combination of the key elements of communication, training, and feedback in order to create motivated, customer-orientated employees. Through employees and managers working together towards a well communicated organisational cause of Internal Marketing, internal procedures can evolve to better service and satisfy customers.  Organisational restructures are an ongoing concern as technological advances, value-adding business process, and globalisation change the way that businesses run and operate. In order to save on costs of operations, employment, and office rental space, downsizing an organisation may initially present itself as a cost-saving practice. Often unconsidered are the front-line customer-facing employees and customers of an organisation. Employees may feel distraught and concerned about losing their job, or having to find a new job, which may affect customer service, and subsequently customers may face the brunt of the domino effect, either intentionally or unintentionally, due to employees’ emotional disconnection from the organisation.  This research is an exploratory study into Internal Marketing, specifically around an organisational restructure, to better understand its impact on employees and customers through different stages of a restructure. Through the use of online surveys, participants were asked to recall an organisational restructure they were involved in within the last five years. They were asked to report their perceptions of Internal Marketing, their own satisfaction with their job at the time, and their perceptions of Customer Satisfaction throughout different stages of the organisational restructure.  The analysis found that Internal Marketing does have a significant positive relationship with Employee Satisfaction both during and after an organisational restructure. Although no significant relationship was found between Employee Satisfaction and Customer Satisfaction at any stage of the restructure, there is a trend within the data suggesting that the relationship may be stronger before and after an organisational restructure.  Benefits and contribution of this research for academics include development of a conceptual model, as well as the benefits and effects of Internal Marketing, and extending the existing literature. For practitioners, benefits include insights into better understanding of the role of Internal Marketing. Specifically, the differences in perception of the practice between employees and managers, and why it is important to understand and address Employee Satisfaction and Customer Satisfaction during an organisational restructure.</p>

The present study aimed to investigate the role of negative feelings on the consumer buying decision. The influence of a brand image, the need for social approval, and negative brand self- expressiveness on brand embarrassment, as well as the influence of embarrassment on brand hate and brand detachment, mediated by interpersonal influence, were investigated. Findings revealed that brand image and the need for social approval do not have any influence on brand embarrassment, while the negative brand self-expressiveness does predict brand embarrassment. On the other side, the findings revealed that brand embarrassment creates brand hate and brand detachment. And, interpersonal influence has a mediating role in the relationship between brand image-brand detachment, negative brand self-expressiveness-brand hate, and negative brand self- expressiveness-brand detachment.

Depression has strong relationship with diabetes mellitus and the aspect of psychology has influence toward the diabetes patient as control. This research aimed to find out the role of psychological factors in dealing with depression suffered by patient of DM-2 and to see the dynamics of both direct and indirect relationship of psychological factors toward the depression of DM-2 patient. The main model is a model that can bring effect of mediation between social support and depression caused by DM-2. Optimism can provide mediating effect of the relationship between social support and self-esteem. Resilience can provide mediating effect of the relationship between social support and self-esteem. Similarly, self-esteem acts as the mediator of the relationship between optimism and resilience toward the depression of DM-2 patient. The result of estimation parameter test showed the direct relationship between social support toward optimism (0.717), resilience (0.811), self-esteem (0.269) and depression (-0.210) and the direct role to depression (-0.397). The higher social support and self-esteem will cause the higher optimism and resilience. On the other hand, the role of self-esteem showed negative coefficient. On the other hand, the role of self-esteem to depression showed a negative coefficient is, the higher self-esteem will be followed by the decrease of depression in patient with DM-2. Keywords: depression, optimism, resilience, self-esteem, social support, DM-2
