Customers' perspectives on the impact of the Pathways to Work Condition Management Programme on their health, wellbeing and vocational activity
Aims: Pathways to Work is a UK initiative aimed at supporting customers on incapacity benefits to return to work. This qualitative study complements previous evaluations of Pathways to Work by exploring customers’ perceptions of the impact of the Condition Management Programme (CMP) offered to claimants with long-term health conditions.
Methods: 39 customers took part in focus groups held at the seven sites where Pathways was originally piloted. The main focus of the discussions was on perceptions of the ways in which participation had impacted on health, well-being and return to work. The discussions were audio-recorded and fully transcribed for analysis using a text analysis framework to enable the development and refinement of categories and overarching patterns in the data.
Results: Perceived impacts on health and wellbeing included a more positive outlook, social contact, changed perceptions of conditions and improvements in health. Some customers also reported an increase in their vocational activity and others felt ready to embark on new activities. Factors associated with positive outcomes included the extent and quality of contact with CMP staff and practical advice about condition management. Factors impeding positive employment outcomes related mainly to obstacles to returning to work.
Conclusions: The results indicated that CMP can assist customers to learn about and manage their health conditions and increase their vocational activity, and that CMP therefore provides a promising means of enabling people with long-term health conditions to regain a fulfilling, productive life
Transformational leadership : inspiration or domination : a critical organisational theory perspective.
Thesis (M.A.)-University of KwaZulu-Natal, Durban, 2010.Within academic literature and contemporary organisations, it has become widely accepted
that transformational leaders are required to harness the potential of their human resources in
the direction of accomplishing organisational objectives and achieving organisational
success. Transformational leaders are typically portrayed as charismatic, visionary
individuals who are primarily concerned with the needs of their followers and who project a
passionate and inspirational attitude within the organisational context. Little research
however, has been directed toward a critical analysis of the power dynamics inherent in the
leader-follower relationship and the discursive practices which influence and are influenced
by this relationship. The current study sought to determine the extent to which a textual
analysis of electronic journal articles pertaining to transformational leadership accurately
reflected the presence of discursive effects. The findings revealed that both the knowledge
products associated with transformational leadership as well as the practice of
transformational leaders were informed by and embedded within a human resources
management (HRM) discourse. As this discourse seeks to advance the interests of
management and the organisation, transformational leadership functions as a mechanism
through which the control and domination of workers is enacted within the workplace.
Transformational leaders, through their alliance with a managerialist ideology, aspire to
motivate employees to transcend their own self-interests and align their values with those of
the organisation thereby engendering compliance, docility and self-domination. Discursive
formations persuade employees to invest their subjectivities in the organisation, producing a
hegemonic situation in which employees become instrumental in their own subordination

Pendent Usnea (Lichens; Ascomycetes; Parmeliaceae) in Western Oregon : taxonomy; morphological characters; and geographical distribution
Pendent Usnea species were collected in western Oregon and examined.
Character states, such as cortex-medulla-axis ratio; fibril length; papilla diameter;
branching patterns; and presence or absence of fibrils, papillae, soredia, isidia; plus
chemistry, were recorded and analyzed by inspection for differences. Historical
names were researched in the literature. A comparison was made between species
concepts used in these accounts, with many conflicting concepts encountered.
Selected morphological characters were examined by scanning electron microscope,
or dissecting microscope, described, and illustrated. The characters reviewed
included articulate fissures; isidia and soredia; cortex-medulla-axis ratio; papillae; and
foveate pits. Species determinations were made for field collections. Names were
found for all specimens inspected without introducing new names at this time. Eight
pendent species were found in western Oregon; they are Usnea cavernosa, Usnea
ceratina, Usnea fillpendula, Usnea hesperina subsp. liturata, Usnea inflata, Usnea
leucosticta, Usnea longissima, and Usnea merrillii. A practical key to taxa with
descriptions is provided and geographic distributions are recorded in tables and maps
Further observations on mechanisms of bone destruction by squamous carcinomas of the head and neck: the role of host stroma.
Mechanisms of bone invasion by squamous carcinomas of the head and neck have been investigated using fresh tumours and established tumour cell lines in an in vitro bone resorption assay with 45Ca-labelled mouse calvaria. Fresh tumours regularly resorb bone in vitro. Activity is consistently reduced by indomethacin. The tumours release E2 prostaglandins (PGE2) in amounts sufficient to account for approximately 50% of the bone resorption observed. Small amounts of non-prostaglandin (indomethacin-resistant) osteolytic factors are also produced. Control non-neoplastic tissues show a variable capacity to resorb bone in vitro; PGE2 levels in these tissues may be related to their content of inflammatory cells. Tumour cell lines also resorb bone in vitro but, for most lines, activity is not significantly blocked by indomethacin and PGE2 levels are generally insufficient to account for the osteolysis observed. Non-prostaglandin bone resorbing factors thus predominate. It is concluded that most squamous cancers of the head and neck are osteolytic in vitro and release a mixture of prostaglandin and non-prostaglandin factors which stimulate osteoclastic bone resorption. These factors are derived from both neoplastic and stromal elements, and are "tumour-associated" rather than "tumour-specific". In vitro bone resorption and prostaglandin release does not correlate with pathological features of the tumour or with post-operative survival
Extension of the composite CBS-QB3 method to singlet diradical calculations
The composite CBS-QB3 method is widely used to obtain accurate energies of
molecules and radicals although its use in the case of singlet diradicals gives
rise to some difficulties. The problem is related to the parameterized
correction this method introduces to account for spin-contamination. We report
a new term specifically designed to describe singlet diradicals separated by at
least one CH2 unit. As a test case, we have computed the formation enthalpy of
a series of diradicals that includes hydrocarbons as well as systems involving
heteroatoms (nitrogen, oxygen). The resulting CBS-QB3 energies are very close
to experiment
Möglichkeiten der Intensivierung des Anbauus von Zwischenfruchtleguminosen mit besonderer Berücksichtigung der Fruchtfolgekrankheiten
In a two-year model crop rotation consisting of overwintering legumes as cover crops followed by maize in the first year and grain peas in the second year, the phytopathological risks and the potential of expanding the cultivation of legume cover crops in minimum tillage systems were examined
