Turismo, un futuro possibile
No full textDi viaggi e di turismo si discute moltissimo e da parecchio tempo, ma il dibattito fatica ad uscire da una situazione di impasse in cui si scontrano le posizioni antitetiche di chi vorrebbe lo sviluppo turistico ad ogni costo e di chi invece lo condanna in ogni suo aspetto. La tesi che qui si sostiene è che sia invece possibile pensare uno sviluppo turistico alternativo, a patto che si ragioni anche dell’organizzazione dei sistemi produttivi e soprattutto del tempo che siamo costretti a dedicare al lavoro nella nostra società

No full textFerdiyanto Tarakolo. Perkembangan Populasi Dan Sistim Pemeliharaan Kerbau Rakyat Di Lembah Napu Kabupaten Poso (dibimbing oleh Kaharudin Kasim dan Padang Hamid). Penelitian ini bertujuan untuk : (1) mengetahui perkembangan populasi kerbau di Lembah Napu Kabupaten Poso, (2) mengetahui sistem pemeliharaan kerbau oleh peternak di Lembah Napu Kabupaten Poso. Penelitian ini dilakukan dengan menggunakan metode survey yang dilengkapi dengan daftar pertanyaan untuk melukiskan kondisi sebelumnya dan faktor yang ada sekarang berdasarkan fakta-fakta yang ada di lapangan. 1). Hasil penelitian menunjukkan bahwa rata-rata umur pejantan kawin pertama 32,31± 3,69 bulan (n=12), dan betina 42,30 ± 3,12 bulan (n=35), dengan lama bunting 11,45 ± 0,11 bulan (n=35), jarak kelahiran 16,55 ± 0,21 bulan (n=35), dan rata-rata frekuensi kawin perkebuntingan 1,75 ± 0,10 kali (n=35), 2) akibat pola pemeliharaan tradisional, maka populasi sangat rendah ditandai persentase kelahiran 28,57%/tahun (n=35) dengan tingkat kematian 13,51% atau bertambah sebanyak 32 ekor selama 3 tahun dengan rata-rata 10,67 ekor/tahun walaupun persentase penyapihan 80,00% (n=8). Peningkatan populasi kerbau hanya mampu bertambah sebanyak 0,34 ekor/tahun yang disebabkan oleh tingkat penjualan 10,33 ekor/tahun (n=24), 3) ternak kerbau di daerah penelitian masih tergolong usaha ternak tradisional dimana, teknik beternaknya masih bersifat sampingan. Cirinya penggembalaan kerbau dilepaskan dan diikat di lapangan/padang pengembalaan untuk memperoleh rumput dan hijauan lapangan. Kerbau tidak diberi makanan tambahan (konsentrat). Pemeliharaan kerbau dengan sistim ikat/pindah dilakukan oleh peternak dengan interval 1-3 kali/hari (n=24), dan 4) penyakit yang sering menyerang adalah ngorok, Cacing, Bloat dan Leher bengkak dengan pengobatan tradisional menggunakan ramuan-ramuan yang terdiri dari Acalypha indica L. (Akar kucing) untuk mengobati penyakit ngorok, Bischofia javanica Blume (Pepolo) untuk mengobati penyakit cacing, Breynia coronata Hook. F. (Teturu) untuk mengobati penyakit bloat, Euphorbia hirta L. (Katuli) untuk mengobati penyakit leher bengkak, Glochidion insigne Muell.(M.A.) J.J.S (Tambone/timbu) untuk mengobati penyakit cacing, dan Jatropha curcas L. (Tatanga) untuk mengobati penyakit leher bengkak dan bloat. Kata Kunci: Kerbau, Produktivitas, dan Manajemen
Easy automated OMA with open source software
No full textIn this paper, we introduce a newly developed clustering tool integrated into pyOMA2, an open-source
Python module designed for conducting Operational Modal Analysis (OMA). pyOMA2 provides easy
access to the most popular algorithms developed over the past two decades, such as Stochastic Subspace
Identification (SSI) and Frequency Domain Decomposition (FDD). It supports the analysis of both single
and multi-setup data measurements and offers interactive plots and geometry definitions to facilitate the
visualization of mode shapes after obtaining modal results. Since version 1.0.1, the software also includes
the ability to estimate uncertainty bounds of modal properties for SSI algorithms.
One of the main advantages of pyOMA2 is its modularity, which facilitates the development of additional functionalities. A prime example is the newly developed clustering handler, a specialized class
that enables users to define and execute various clustering strategies to automate the selection of modal
parameters from SSI results. This tool enables users to implement and compare a large number of the
most popular algorithms introduced over the last 15 years, all within the same analysis framework. Furthermore, users have the flexibility to mix specific strategies from different algorithms to customise the
clustering process accordingly to their needs. Additionally, the integration with the popular machine
learning module scikit-learn has expanded the range of available clustering algorithms, providing users
with even more options for their analyses. All these capabilities are illustrated in the paper through applications to both a numerical example and real-world datasets
Multi-Criterial Model for Weighting Biological Risk Factors in Multiple Sclerosis: Clinical and Health Insurance Implications
No full textThe etiology of Multiple Sclerosis (MS) remains undetermined. Its pathogenic risk factors are thought to play a negligible role individually in the development of the disease, instead assuming a pathogenic role when they interact with each other. Unfortunately, the statistical weighting of this pathogenic role in predicting MS risk is currently elusive, preventing clinical and health insurance applications. Here, we aim to develop a population-based multi-criterial model for weighting biological risk factors in MS; also, to calculate the individual MS risk value useful for health insurance application. Accordingly, among 596 MS patients retrospectively assessed at the time of diagnosis, the value of vitamin D 30 Kg/m2, female sex, degree of family kinship, and the range of age at onset of 20-45 years were considered as biological risk factors for MS. As a result, in a 30-year-old representative patient having a BMI of 15 and second degree of family kinship for MS, the major developmental contributor for disease is the low vitamin D serum level of 10 nm/L, resulting in an MS risk of 0.110 and 0.106 for female and male, respectively. Furthermore, the Choquet integral applied to uncertain variables, such as biological risk factors, evidenced the family kinship as the main contributor, especially if coincident with the others, to the MS risk. This model allows, for the first time, for the risk stratification of getting sick and the application of the health insurance in people at risk for MS

The Deployment of Corporate Social Responsibility in Multinational Corporations’ Subsidiaries: Evidence from Africa
No full textThis study examines how multinational corporations’ (MNCs) subsidiaries manage institutional complexity when deploying their corporate social responsibility (CSR) activities in Africa. Building on insights from international business studies of CSR and recent development in comparative institutionalism, we explore how distinct institutional forces combine to shape subsidiary’s CSR behaviour across five African countries. Relying on 33 interviews with managers at 26 subsidiaries operating in Angola, Egypt, Ghana, Kenya and South Africa, we identified patterns of variations in CSR deployment across these countries. Our findings reveal that MNCs’ subsidiaries mobilize the CSR strategy of their parent firm to demonstrate their compliance with their headquarters’ expectations, but also complement this minimum level of requirement with elements that reflect the needs from the local business system. As a whole, our findings reveal the complex bricolage undertaken by subsidiary’s managers to tailor their CSR strategy in ways that meet the contradictory institutional forces they fac
Acute Symptomatic Sinus Bradycardia in High-Dose Methylprednisolone Therapy in a Woman With Inflammatory Myelitis: A Case Report and Review of the Literature
No full textHigh dose corticosteroid therapy is widely used as attack therapy of inflammatory central nervous system disorders and can induce several adverse reactions. Bradycardia is an infrequent event after corticosteroids administration and is often asymptomatic. We report a case of a woman admitted to the neurological department of our hospital for paraesthesias of the lower limbs. She received adiagnosis of inflammatory myelitis and high dose corticosteroid therapy was prescribed. During the therapy she complained of chest tightness, dyspnoea, weakness and malaise. An electrocardiogram revealed sinus bradycardia. A significant increase in body weight, probably due to plasma volume expansion, was detected. Bradycardia and high blood pressure spontaneously resolved in few days. We provide a collection and a statistical analysis of literature data about steroid induced bradycardia. We found that higher total doses are associated with lower pulse rate and symptomatic bradycardia. Bradycardia is more frequent in older patients and those with underlying cardiac disease or with autonomic disturbance. However clinicians must be aware about the occurrence of symptomatic bradycardia in all patients who undergo high dose corticosteroid therapy, not only in those at risk, to early detect and treat this potentially dangerous condition
