Interwar Britain witnessed the rapid rise of road transport as a serious competitor to the railways. This article examines road–rail competition for freight traffic. It demonstrates that, contrary to previous accounts—which have been highly critical of the railway companies—their failure to prevent rapid loss of traffic to the roads was the inevitable consequence of the regulatory framework under which the railways had been returned to private control in 1921. Given the constraints imposed by this framework, price competition with road hauliers would have further depressed railway company profits. Railway policy thus concentrated on pressing for a revision of the legislative framework governing road–rail competition.

The problem of spurious excitation of gravity waves in the context of four-dimensional data assimilation is investigated using a simple model of balanced dynamics. The model admits a chaotic vortical mode coupled to a comparatively fast gravity wave mode, and can be initialized such that the model evolves on a so-called slow manifold, where the fast motion is suppressed. Identical twin assimilation experiments are performed, comparing the extended and ensemble Kalman filters (EKF and EnKF, respectively). The EKF uses a tangent linear model (TLM) to estimate the evolution of forecast error statistics in time, whereas the EnKF uses the statistics of an ensemble of nonlinear model integrations. Specifically, the case is examined where the true state is balanced, but observation errors project onto all degrees of freedom, including the fast modes. It is shown that the EKF and EnKF will assimilate observations in a balanced way only if certain assumptions hold, and that, outside of ideal cases (i.e., with very frequent observations), dynamical balance can easily be lost in the assimilation. For the EKF, the repeated adjustment of the covariances by the assimilation of observations can easily unbalance the TLM, and destroy the assumptions on which balanced assimilation rests. It is shown that an important factor is the choice of initial forecast error covariance matrix. A balance-constrained EKF is described and compared to the standard EKF, and shown to offer significant improvement for observation frequencies where balance in the standard EKF is lost. The EnKF is advantageous in that balance in the error covariances relies only on a balanced forecast ensemble, and that the analysis step is an ensemble-mean operation. Numerical experiments show that the EnKF may be preferable to the EKF in terms of balance, though its validity is limited by ensemble size. It is also found that overobserving can lead to a more unbalanced forecast ensemble and thus to an unbalanced analysis.

Denna uppsats har till syfte att få en överblick av hälsoläget inom Nås provinsialläkaredistrikt under hösten 1918 och våren 1919, då spanska sjukan grasserade. Uppsatsen undersöker vilken belastning spanska sjukan blev för epidemisjukvården och hur kommunen sörjde för den under epidemin. Mortaliteten under spanska sjukan visade ett liknande mönster som i andra delar av världen där ett stort antal unga människor avled. I undersökningen belyses även könstillhörigheten samt yrkeskategorisering av de döda. Under epidemins inledning var männen i majoritet men senare under epidemin blir det flest kvinnor, som avled i sviterna av spanskan. Mortalitetens yrkeskategorisering visar en klar majoritet för kroppsarbetare av olika slag samt hustrur till hemmansägare eller skogsarbetare och industriarbetare. Dödligheten var störst inom Vansbro municipalsamhälle under epidemin, beroende på att järnvägen och många resande passerade där. Pressens rapportering visar att Vansbro / Dala – Järna drabbades hårt av spanska sjukan.Som källmaterial användes provincialläkarrapporter från medicinalstyrelsens arkiv, kommunalnämndens och hälsovårdsnämndens protokoll, dödböcker och tidningartiklar ur tre lokala dagstidningar.

Syftet med detta arbete är att utforska hur Svenska Turistföreningen, i sina årsböcker mellan 1915-1919, förhåller sig i sina utsagor om människorna och landskapen till det regionala och det nationella. De frågeställningar som använts har varit: Vilka rumsligt anknutna utsagor finns om befolkningen i de olika landskapen och om landskapen som sådana? I vilken ut-sträckning bär dessa utsagor en regional eller nationell prägel? Sätts det regionala i kontrast till det nationella, eller ses det regionala som en del av det nationella? Hur talrika är dessa utsagor? Finns det en tendens att vissa landskapsskildringar innehåller fler eller färre av dessa utsagor? Finns det en förändring i dessa utsagor under den tid som undersökts? Källmaterialet har utgjorts av Svenska Turistföreningens årsskrifter mellan 1915-1919. Dessa behandlar Uppland, Småland, Bohuslän, Västmanland samt Skåne i den ordningen. För att uppnå syftet har en kvalitativ textanalys använts. Resultatet pekar på att det finns rumsligt anknutna utsa-gor i alla böcker men mängden och arten varierar kraftigt. Det finns alltså landskap som ges en starkare regionalitet, men i dessa fall knyter man detta landskap till nationen genom att t.ex. hävda att det regionala i landskapet är något utmärkande för hela landet.

Vilhelm Ekelund och den fransk-italienska kultursfären: Några nedslag i de tidiga prosaverken – från Antikt ideal (1909) till Attiskt i fågelperspektiv (1919). (Vilhelm Ekelund and the French and Italian cultural heritage: A study of his early prose – from Antikt ideal (1909) to Attiskt i fågelperspektiv (1919)). The Swedish poet, essayist and aphorist Vilhelm Ekelund was not only influenced by German literature and philosophy, he also wrote extensive literary criticism on the subject of Romance language authors. This article discusses Ekelund’s relationship to some of the most influential French and Italian writers – as it can be seen in his work during the period 1909-1919. This relationship was ambiguous: he paid homage to French authors such as Montaigne, Montesquieu, Stendhal and Comte – as well as to the Italian poet and philosopher Leopardi – but he also severely criticized such distinguished writers as Baudelaire, Rousseau and Maupassant. One conclusion of this article is that the authors praised by Ekelund all venerate the Greek and Roman cultural heritage, whereas the despised novelists and poets were, in his opinion, either too “modern” or too “feminine” – both highly pejorative adjectives in the author’s terminology. It is also noted that Ekelund’s most ferocious attacks date from the first part of the decade, before he entered a more harmonic period with the works Metron (1918) and Attiskt i fågelperspektiv (1919).

Despite the recent flourishing of ecopsychology research, risks may be involved if ecopsychology remains a loosely defined paradigm. We suggest that drawing from some of the central themes of Theodore Roszak’s The Voice of the Earth (1992), a seminal text of ecopsychology, may help to elucidate the unique contribution of ecopsychology and its sustained relevance for environmentally focused psychologies. To provide a comprehensive review, we consider The Voice of the Earth by placing this text in the context of Roszak’s broader body of literature, discussing his earlier and more recent works. We particularly focus on the theme of spiritual experience throughout Roszak’s literature, as we believe that this is one of the more unique and important aspects of his work that has implications for the future development of ecopsychology as a paradigm and social movement. In conclusion, we suggest that Roszak’s emphasis on the value of a spiritual or animistic experience of nature, as a means of fostering empathy toward the natural world, may assist in providing meaningful focus to contemporary ecopsychology.
