One-year outcomes of repeated adjunctive photodynamic therapy during periodontal maintenance: a proof-of-principle randomized-controlled clinical trial

BACKGROUND: Single photodynamic therapy (PDT) has been effective in initial periodontal therapy, but only improved bleeding on probing (BoP) in maintenance patients after a single use. Repeated PDT has not been addressed. OBJECTIVES: To study the possible added benefits of repeated adjunctive PDT to conventional treatment of residual pockets in patients enrolled in periodontal maintenance. MATERIAL AND METHODS: Ten maintenance patients with 70 residual pockets [probing pocket depth (PPD)>or=5 mm] were randomly assigned for treatment five times in 2 weeks (Days 0, 1, 2, 7, 14) with PDT (test) or non-activated laser (control) following debridement. The primary outcome variable was PPD, and the secondary variables were clinical attachment level (CAL) and BoP. These were assessed at 3, 6 and 12 months following the interventions. RESULTS: Greater PPD reductions were observed in the test (-0.67 +/- 0.34; p=0.01) compared with the control patients (-0.04 +/- 0.33; NS) after 6 months. Significant CAL gain (+0.52 +/- 0.31; p=0.01) was noted for the test, but not in the control (-0.27 +/- 0.52; NS) patients after 6 months. BoP percentages decreased significantly in test (97-64%, 67%, 77%), but not control patients after 3, 6 and 12 months. CONCLUSIONS: Repeated (five times) PDT adjunctive to debridement yielded improved clinical outcomes in residual pockets in maintenance patients. The effects were best documented after 6 months.

The Postmodern ‘Turn’ in Social Work: The Challenges of Identity and Equality

Diversity and demands for equality have challenged fixed notions of identity amongst the diverse populations of Europe. This development has prompted discourses about the significance of fluidity and multiplicity in identities that have given prominence to postmodern theories in the profession of social work. A number of social work educators have contributed to the ensuing debates. Walter Lorenz’s work has contributed substantially to developments on this front by:highlighting the dangers of essentialising fixed identities in professional practice, referring to the failure of social workers to live up to professional values and ideals in the Nazi attack on Jews and others who were different from the Aryan norms that Hitler’s regime sought to impose; arguing for racial equality in multicultural Europe; and ensuring that social work theories and practice engaged with innovations in the social sciences more generally to improve the profession’s research, theoretical and practice bases. In this article, I engage with crucial debates that have shaped the profession during the post-war period, honouring Walter Lorenz’s contributions to them in the process.

An overview of positive and negative effects of gender-fair language use

The basic principle of gender-fair language is symmetric linguistic treatment of women and men. Depending on the structure of the respective language, two principle strategies can be deployed to make a language gender-fair. In languages with few gender-differentiating forms, such as English, there is a tendency towards neutralization. Here, gender-unmarked forms such as police officer or chairperson are used to substitute the male-biased policeman or chairman. The second strategy, feminization, implies that feminine forms of human nouns are used more frequently and systematically to make female referents visible.Since the 1970s, gender-fair language has been suggested, if not prescribed, for both scientific and official texts and its positive effects are widely documented. The use of gender-fair language increases the cognitive availability of feminine exemplars. Also in an applied context women responding to job advertisements formulated in gender-fair language feel more motivated to apply for the position. However, "side effects" of gender-fair language have also been observed: For instance, women referred to with a gender-fair title (e.g. chairperson) were evaluated as lower in status than women referred to with a masculine generic (e.g. chairman). Similarily, social initiatives framed with the use of gender-fair language were evaluated less-favourably than initiatives using traditional language. This presentation presents the gender-fair language use in the framework of a social dilemma. In order to protect themselves (or initiatives they stand for) from being ascribed incompetence or a lower status, women may avoid feminine forms and thus contribute to the perpetuation of gender-unfair language, which may be detrimental for women in general. Raising awareness for this social concern, and framing it both in terms of group and individual interest can direct the discussion about gender-fair language into a broader perspective of gender equality.

A stochastic principle behind polar properties of condensed molecular matter

A statistical mechanics view leads to the conclusion that polar molecules allowed to populate a degree of freedom for orientational disorder in a condensed phase thermalize into a bi-polar state featuring zero net polarity. In cases of orientational disorder polar order of condensed molecular matter can only exist in corresponding sectors of opposite average polarities. Channel type inclusion compounds, single component molecular crystals, solid solutions, optically anomalous crystals, inorganic ionic crystals, biomimetic crystals and biological tissues investigated by scanning pyroelectric and phase sensitive second harmonic generation microscopy all showed domains of opposite polarities in their final grown state. For reported polar molecular crystal structures it is assumed that kinetic hindrance along one direction of the polar axis is preventing the formation of a bi-polar state, thus allowing for a kinetically controlled mono-domain state. In this review we summarize theoretical and experimental findings leading to far reaching conclusions on the polar state of solid molecular matter. “… no stationary state … of a system has an electrical dipole moment.” P. W. Anderson, Science, 1972, 177, 393.

Hybrid bodies in cyborg sports? The case of Oscar Pistorius

The capabilities of postmodern biotechnology inevitably lead to questioning if it is morally acceptable to use all possibilities offered by technology. In sport, this very complex issue is dealt with by drawing clear boundaries between naturalness and artificiality. Currently, new biotechnology is constantly being produced and with this, boundaries between naturalness and artificiality, between normal and abnormal, human and hybrid are constantly shifting . “Human enhancement” is a fascinating prism that reflects contemporary questions of participation, justice, equality and the autonomy of the subject in all social fields. The area of elite sports is particularly affected by “human enhancement”, according to the principle of exceeding what has come before, of aiming higher, faster and further. This paper analyses the postulated “naturalness” in the regulative and normalising function in the area of elite sports, in connection with Foucault’s theory of governmentality. The example of the South African sprinter Oscar Pistorius appears to be particularly suited to illustrate current definition difficulties in the area of disabled and non-disabled people in differentiated competitive sports. His is a vivid example of a multifaceted body-sociological analysis of current sport culture and the construction of reality or naturalness in the framework of the discourse of drafting and negotiating the accreditation for sprint competitions of non-disabled athletes, most recently in the London Olympics 2012. Using the case study of Oscar Pistorius, the negotiating processes in relation to the argumentation logic, dynamics and resistance in shifting distinctions are presented in detail using the fundamental documents of the IOC, IPC, CAS and IAAF. Represented through the inclusion and exclusion processes are hierarchies of the body that are (re)consolidated and transformed. The central question emerges as to how the worth of equal opportunity and fairness in regard to “naturalness” can be reconsolidated or transformed.

Troublesome Issues: Current Debates on Tensions between Gender Equality and Cultural Diversity in Austria

This paper will first deal with the legal and social situation of Islam and Muslims in Austria and then turn to particular “troublesome issues” at the intersection of gender equality and ethnic/religious diversity. The public debate on Muslims particularly focuses on the notion “not willing to integrate” and in the assumption of “parallel societies”. Hierarchical gender relations and “harmful traditions” such as veiling, female genital cutting, forced marriage and honour based violence recently became the centre of attention. We will show that the Austrian debate on these issues is shaped by the idea of “dangerous cultural difference” as something coming from outside and being concentrated in segregated Muslim enclaves. Despite the public authorities’ rejection of the idea that Islam was responsible for “harmful traditions”, legal as well as political measures in Austria not only combat violence against women but also fuel “cultural anxieties” between different ethnic and religious groups.

Gender-fair language use in online job advertisements - relations to job status and gender equality

Purpose Gender fair language use in job advertisements has been shown to impact the outcome of personnel selections. It is thus important to assess, to what extent gender fair language is used in job advertisements and with which factors it is associated, e.g., language, culture, status, and gender typicality of profession. Design/Methodology In the present research we investigated gender fair language use in job advertisements published online in four European countries with different socio-economic rankings of gender equality (World Economic Forum, 2011), namely Austria (rank 34), Czech Republic (75), Poland (42), and Switzerland (10). From four lines of business with different percentages of female employees – steels/metals, science, restaurants/food services, and health care –we randomly selected 100 job advertisements, summing up to 1600 job advertisements in total. Results A first analysis of the Swiss data indicates that the phrasing of job advertisements is closely related to a profession’s gender typicality (e.g., merely masculine forms are used in steels and metals, gender-fair forms in healthcare). Feminine forms however are almost never used. Cross-cultural comparisons will be presented. Limitations We analyzed job advertisements of four specific lines of business in four European countries. To what extend results can be generalized remains an open question. Research/Practical Implications The present data provide a sound basis for future studies on gender fair language use in job advertisements. Furthermore it sheds a light on how companies comply with national guidelines of gender equality. Originality/Value This is the first time that gender fair language use in job advertisements is investigated (a) across different countries and languages and (b) considering status and gender typicality of professions.

Gender references in job advertisements – relations to job status and gender equality

Research has shown that gender references in job advertisements play an important role for gender (in)equality in personnel selection. The use of pair forms (masculine and feminine form) in German-language job advertisements, for example, was found to reduce the lack of fit between women and leadership roles (Horvath & Sczesny, 2013). Therefore the present study addresses the question which forms of gender reference are used in job advertisements, how these forms are distributed in different countries and how language use is related to gender typicality and status of the job. We collected job advertisements published online in four countries with different rankings of gender equality (i.e., Switzerland, Austria, Poland, and Czech Republic; World Economic Forum, 2011). We randomly selected 100 advertisements per country from four branches that are characterized by different proportions of female and male employees: steels/metals, science, restaurants/food services, and health care. The advertisements were analyzed with regard to gender references as well as different indicators of job status. The results show that, in general, men and women are addressed more equally in Swiss and Austrian job advertisements compared to Polish and Czech job advertisements. The results also show that women and men are addressed more equally in branches where the proportion of women is high than where the proportion of women is low. We thus can conclude that the use of gender references is associated with the degree of gender equality achieved in a country and with the gender typicality of a profession.
